Inclusion: providing effective learning opportunities for all pupils

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

[Schools have a responsibility to provide a broad and balanced curriculum for all pupils. The National Curriculum is the starting point for planning a school curriculum that meets the specific needs of individuals and groups of pupils.

This statutory inclusion statement on providing effective learning opportunities for all pupils outlines how teachers can modify, as necessary, the National Curriculum programmes of study to provide all pupils with relevant and appropriately challenging work at each key stage. It sets out three principles that are essential to developing a more inclusive curriculum:
a) Setting suitable learning challenges
b) Responding to pupils' diverse learning needs
c) Overcoming potential barriers to learning and assessment for individuals and groups of pupils.

Applying these principles should keep to a minimum the need for aspects of the National Curriculum to be disapplied for a pupil.

Schools are able to provide other curricular opportunities outside the National Curriculum to meet the needs of individuals or groups of pupils such as speech and language therapy and mobility training.]

Three principles for inclusion

In planning and teaching the National Curriculum, teachers are required to have due regard to the following principles.

A Setting suitable learning challenges

1. Teachers should aim to give every pupil the opportunity to experience success in learning and to achieve as high a standard as possible. The National Curriculum programmes of study set out what most pupils should be taught at each key stage - but teachers should teach the knowledge, skills and understanding in ways that suit their pupils' abilities. This may mean choosing knowledge, skills and understanding from earlier or later key stages so that individual pupils can make progress and show what they can achieve. Where it is appropriate for pupils to make extensive use of content from an earlier key stage, there may not be time to teach all aspects of the age-related programmes of study. A similarly flexible approach will be needed to take account of any gaps in pupils' learning resulting from missed or interrupted schooling [for example, that may be experienced by travellers, refugees, those in care or those with long-term medical conditions, including pupils with neurological problems, such as head injuries, and those with degenerative conditions].

2. For pupils whose attainments fall significantly below the expected levels at a particular key stage, a much greater degree of differentiation will be necessary. In these circumstances, teachers may need to use the content of the programmes of study as a resource or to provide a context, in planning learning appropriate to the age and requirements of their pupils. (Teachers may find QCA's guidance on planning work for pupils with learning difficulties a helpful companion to the programmes of study.)

3. For pupils whose attainments significantly exceed the expected level of attainment within one or more subjects during a particular key stage, teachers will need to plan suitably challenging work. As well as drawing on materials from later key stages or higher levels of study, teachers may plan further differentiation by extending the breadth and depth of study within individual subjects or by planning work which draws on the content of different subjects.(Teachers may find QCA's guidance on meeting the requirements of gifted and talented pupils a helpful companion to the programmes of study.)
B Responding to pupils' diverse learning needs

1. When planning, teachers should set high expectations and provide opportunities for all pupils to achieve, including boys and girls, pupils with special educational needs, pupils with disabilities, pupils from all social and cultural backgrounds, pupils of different ethnic groups including travellers, refugees and asylum seekers, and those from diverse linguistic backgrounds. Teachers need to be aware that pupils bring to school different experiences, interests and strengths which will influence the way in which they learn. Teachers should plan their approaches to teaching and learning so that all pupils can take part in lessons fully and effectively.

2. To ensure that they meet the full range of pupils' needs, teachers should be aware of the requirements of the equal opportunities legislation that covers race, gender and disability (the Sex Discrimination Act 1975, the Race Relations Act 1976, the Disability Discrimination Act 1995).

3. Teachers should take specific action to respond to pupils' diverse needs by:
a) creating effective learning environments
b) securing their motivation and concentration
c) providing equality of opportunity through teaching approaches
d) using appropriate assessment approaches
e) setting targets for learning.

[Examples for B/3a - creating effective learning environments

Teachers create effective learning environments in which:
* the contribution of all pupils is valued
* all pupils can feel secure and are able to contribute appropriately
* stereotypical views are challenged and pupils learn to appreciate and view positively differences in others, whether arising from race, gender, ability or disability
* pupils learn to take responsibility for their actions and behaviours both in school and in the wider community
* all forms of bullying and harassment, including racial harassment, are challenged
* pupils are enabled to participate safely in clothing appropriate to their religious beliefs, particularly in subjects such as science, design and technology and physical education.

Examples for B/3b - securing motivation and concentration

Teachers secure pupils' motivation and concentration by:
* using teaching approaches appropriate to different learning styles
* using, where appropriate, a range of organisational approaches, such as setting, grouping or individual work, to ensure that learning needs are properly addressed
* varying subject content and presentation so that this matches their learning needs
* planning work which builds on their interests and cultural experiences
* planning appropriately challenging work for those whose ability and understanding are in advance of their language skills
* using materials which reflect social and cultural diversity and provide positive images of race, gender and disability
* planning and monitoring the pace of work so that they all have a chance to learn effectively and achieve success
* taking action to maintain interest and continuity of learning for pupils who may be absent for extended periods of time.

Examples for B/3c - providing equality of opportunity

Teaching approaches that provide equality of opportunity include:
* ensuring that boys and girls are able to participate in the same curriculum, particularly in science, design and technology and physical education
* taking account of the interests and concerns of boys and girls by using a range of activities and contexts for work and allowing a variety of interpretations and outcomes, particularly in English, science, design and technology, ICT, art and design, music and physical education
* avoiding gender stereotyping when organising pupils into groups, assigning them to activities or arranging access to equipment, particularly in science, design and technology, ICT, music and physical education
* taking account of pupils' specific religious or cultural beliefs relating to the representation of ideas or experiences or to the use of particular types of equipment, particularly in science, design and technology, ICT and art and design
* enabling the fullest possible participation of pupils with disabilities or particular medical needs in all subjects, offering positive role models and making provision, where necessary, to facilitate access to activities with appropriate support, aids or adaptations. (See Overcoming potential barriers to learning and assessment for individuals and groups of pupils.)

Examples for B/3d - using appropriate assessment approaches

Teachers use appropriate assessment approaches that:
* allow for different learning styles and ensure that pupils are given the chance and encouragement to demonstrate their competence and attainment through appropriate means
* are familiar to the pupils and for which they have been adequately prepared
* use materials which are free from discrimination and stereotyping in any form
* provide clear and unambiguous feedback to pupils to aid further learning.

Examples for B/3e - setting targets for learning

Teachers set targets for learning that:
* build on pupils' knowledge, experiences, interests and strengths to improve areas of weakness and demonstrate progression over time
* are attainable and yet challenging and help pupils to develop their self-esteem and confidence in their ability to learn.]

C Overcoming potential barriers to learning and assessment for individuals and groups of pupils

[A minority of pupils will have particular learning and assessment requirements which go beyond the provisions described in sections A and B and, if not addressed, could create barriers to learning. These requirements are likely to arise as a consequence of a pupil having a special educational need or disability or may be linked to a pupil's progress in learning English as an additional language.]

1. Teachers must take account of these requirements and make provision, where necessary, to support individuals or groups of pupils to enable them to participate effectively in the curriculum and assessment activities. During end of key stage assessments, teachers should bear in mind that special arrangements are available to support individual pupils.

Pupils with special educational needs

2. Curriculum planning and assessment for pupils with special educational needs must take account of the type and extent of the difficulty experienced by the pupil. Teachers will encounter a wide range of pupils with special educational needs, some of whom will also have disabilities (see paragraphs C/4 and C/5). In many cases, the action necessary to respond to an individual's requirements for curriculum access will be met through greater differentiation of tasks and materials, consistent with school-based intervention as set out in the SEN Code of Practice. A smaller number of pupils may need access to specialist equipment and approaches or to alternative or adapted activities, consistent with school-based intervention augmented by advice and support from external specialists as described in the SEN Code of Practice, or, in exceptional circumstances, with a statement of special educational need.

Teachers should, where appropriate, work closely with representatives of other agencies who may be supporting the pupil.

3. Teachers should take specific action to provide access to learning for pupils with special educational needs by:
a) providing for pupils who need help with communication, language and literacy
b) planning, where necessary, to develop pupils' understanding through the use of all available senses and experiences
c) planning for pupils' full participation in learning and in physical and practical activities
d) helping pupils to manage their behaviour, to take part in learning effectively and safely, and, at key stage 4, to prepare for work
e) helping individuals to manage their emotions, particularly trauma or stress, and to take part in learning.

[Examples for C/3a - helping with communication, language and literacy

Teachers provide for pupils who need help with communication,
language and literacy through:
* using texts that pupils can read and understand
* using visual and written materials in different formats, including large print, symbol text and Braille
* using ICT, other technological aids and taped materials
* using alternative and augmentative communication, including signs and symbols
* using translators, communicators and amanuenses.

Examples for C/3b - developing understanding

Teachers develop pupils' understanding through the use of all available senses and experiences, by:
* using materials and resources that pupils can access through sight, touch, sound, taste or smell
* using word descriptions and other stimuli to make up for a lack of first-hand experiences
* using ICT, visual and other materials to increase pupils' knowledge of the wider world
* encouraging pupils to take part in everyday activities such as play, drama, class visits and exploring the environment.

Examples for C/3c - planning for full participation

Teachers plan for pupils' full participation in learning and in physical and practical activities through:
* using specialist aids and equipment
* providing support from adults or peers when needed
* adapting tasks or environments
* providing alternative activities, where necessary.

Examples for C/3d - managing behaviour

Teachers help pupils to manage their behaviour, take part in learning effectively and safely, and, at key stage 4, prepare for work by:
* setting realistic demands and stating them explicitly
* using positive behaviour management, including a clear structure of rewards and sanctions
* giving pupils every chance and encouragement to develop the skills they need to work well with a partner or a group
* teaching pupils to value and respect the contribution of others
* encouraging and teaching independent working skills
* teaching essential safety rules.

Examples for C/3e - managing emotions

Teachers help individuals manage their emotions and take part in learning through:
* identifying aspects of learning in which the pupil will engage and plan short-term, easily achievable goals in selected activities
* providing positive feedback to reinforce and encourage learning and build self-esteem
* selecting tasks and materials sensitively to avoid unnecessary stress for the pupil
* creating a supportive learning environment in which the pupil feels safe and is able to engage with learning
* allowing time for the pupil to engage with learning and gradually increasing the range of activities and demands.]

Pupils with disabilities

4. Not all pupils with disabilities will necessarily have special educational needs. Many pupils with disabilities learn alongside their peers with little need for additional resources beyond the aids which they use as part of their daily life, such as a wheelchair, a hearing aid or equipment to aid vision. Teachers must take action, however, in their planning to ensure that these pupils are enabled to participate as fully and effectively as possible within the National Curriculum and the statutory assessment arrangements. Potential areas of difficulty should be identified and addressed at the outset of work, without recourse to the formal provisions for disapplication.

5. Teachers should take specific action to enable the effective participation of pupils with disabilities by:
a) planning appropriate amounts of time to allow for the satisfactory completion of tasks
b) planning opportunities, where necessary, for the development of skills in practical aspects of the curriculum
c) identifying aspects of programmes of study and attainment targets that may present specific difficulties for individuals.

[Examples for C/5a - planning to complete tasks

Teachers plan appropriate amounts of time to allow pupils to complete tasks satisfactorily through:
* taking account of the very slow pace at which some pupils will be able to record work, either manually or with specialist equipment, and of the physical effort required
* being aware of the high levels of concentration necessary for some pupils when following or interpreting text or graphics, particularly when using vision aids or tactile methods, and of the tiredness which may result
* allocating sufficient time, opportunity and access to equipment for pupils to gain information through experimental work and detailed observation, including the use of microscopes
* being aware of the effort required by some pupils to follow oral work, whether through use of residual hearing, lip reading or a signer, and of the tiredness or loss of concentration which may occur.

Examples for C/5b - developing skills in practical aspects

Teachers create opportunities for the development of skills in practical aspects of the curriculum through:
* providing adapted, modified or alternative activities or approaches to learning in physical education and ensuring that these have integrity and equivalence to the National Curriculum and enable pupils to make appropriate progress
* providing alternative or adapted activities in science, art and design and design and technology for pupils who are unable to manipulate tools, equipment or materials or who may be allergic to certain types of materials
* ensuring that all pupils can be included and participate safely in geography fieldwork, local studies and visits to museums, historic buildings and sites.

Examples for C/5c - overcoming specific difficulties

Teachers overcome specific difficulties for individuals presented by aspects of the programmes of study and attainment targets through:
* using approaches to enable hearing impaired pupils to learn about sound in science and music
* helping visually impaired pupils to learn about light in science, to access maps and visual resources in geography and to evaluate different products in design and technology and images in art and design
* providing opportunities for pupils to develop strength in depth where they cannot meet the particular requirements of a subject, such as the visual requirements in art and design and the singing requirements in music
* discounting these aspects in appropriate individual cases when required to make a judgement against level descriptions.]

Pupils who are learning English as an additional language

6. Pupils for whom English is an additional language have diverse needs in terms of support necessary in English language learning. Planning should take account of such factors as the pupil's age, length of time in this country, previous educational experience and skills in other languages. Careful monitoring of each pupil's progress in the acquisition of English language skills and of subject knowledge and understanding will be necessary to confirm that no learning difficulties are present.

7. The ability of pupils for whom English is an additional language to take part in the National Curriculum may be ahead of their communication skills in English. Teachers should plan learning opportunities to help pupils develop their English and should aim to provide the support pupils need to take part in all subject areas.

8. Teachers should take specific action to help pupils who are learning English as an additional language by:
a) developing their spoken and written English
b) ensuring access to the curriculum and to assessment.

[Examples for C/8a - developing spoken and written English

Teachers develop pupils' spoken and written English through:
* ensuring that vocabulary work covers both the technical and everyday meaning of key words, metaphors and idioms
* explaining clearly how speaking and writing in English are structured to achieve different purposes, across a range of subjects
* providing a variety of reading material [for example, pupils' own work, the media, ICT, literature, reference books] that highlight the different ways English is used, especially those that help pupils to understand society and culture
* ensuring that there are effective opportunities for talk and that talk is used to support writing in all subjects
* where appropriate, encouraging pupils to transfer their knowledge, skills and understanding of one language to another, pointing out similarities and differences between languages
* building on pupils' experiences of language at home and in the wider community, so that their developing uses of English and other languages support one another.

Examples for C/8b - ensuring access

Teachers make sure pupils have access to the curriculum and to assessment through:
* using accessible texts and materials that suit pupils' ages and levels of learning
* providing support by using ICT or video or audio materials, dictionaries and translators, readers and amanuenses
* using home or first language, where appropriate.]

Additional information for science

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Teachers may find the following additional information helpful when implementing the statutory inclusion statement: Providing effective learning opportunities for all pupils. Teachers need to consider the full requirements of the inclusion statement when planning for individuals or groups of pupils. There are specific references to science in the examples for B/3a, B/3c, C/5a, C/5b and C/5c.

To overcome any potential barriers to learning in science, some pupils may require:
* support to overcome difficulties with mobility or manipulative skills so that they can participate as fully and as safely as possible in experimental work. Support could be provided [for example, by adapting or using alternative activities, adapting equipment or by using specialist items, including ICT, or providing adult or peer support]
* additional time to compensate for difficulties in managing visual information, particularly when making observations and accessing information in experimental work or through the use of microscopes
* support in lessons about light so that despite their visual impairment pupils are able to gain as much access as possible to the activities [for example, by use of ICT, by using their knowledge that many light sources produce heat]
* support in lessons about sounds so that despite their hearing impairment pupils are able to gain as much access as possible to activities [for example, by the use of oscilloscopes and sound level meters to provide visual demonstrations].

In assessment:
* pupils who are unable to use equipment and materials, including those who are visually or hearing impaired, may be unable to achieve certain aspects of the level descriptions. When a judgement against level descriptions is required, assessment of progress should discount these identified aspects.

Use of language across the curriculum

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

1. Pupils should be taught in all subjects to express themselves correctly and appropriately and to read accurately and with understanding. Since standard English, spoken and written, is the predominant language in which knowledge and skills are taught and learned, pupils should be taught to recognise and use standard English.

Writing

2. In writing, pupils should be taught to use correct spelling and punctuation and follow grammatical conventions. They should also be taught to organise their writing in logical and coherent forms.

Speaking

3. In speaking, pupils should be taught to use language precisely and cogently.

Listening

4. Pupils should be taught to listen to others, and to respond and build on their ideas and views constructively.

Reading

5. In reading, pupils should be taught strategies to help them read with understanding, to locate and use information, to follow a process or argument and summarise, and to synthesise and adapt what they learn from their reading.

6. Pupils should be taught the technical and specialist vocabulary of subjects and how to use and spell these words. They should also be taught to use the patterns of language vital to understanding and expression in different subjects. These include the construction of sentences, paragraphs and texts that are often used in a subject [for example, language to express causality, chronology, logic, exploration, hypothesis, comparison, and how to ask questions and develop arguments].

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Use of information and communication technology across the curriculum

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

1. Pupils should be given opportunities to apply and develop their ICT capability through the use of ICT tools to support their learning in all subjects (with the exception of physical education at key stages 1 and 2) (at key stage 1, there are no statutory requirements to teach the use of ICT in the programmes of study for the non-core foundation subjects. Teachers should use their judgement to decide where it is appropriate to teach the use of ICT across these subjects at key stage 1. At other key stages, there are statutory requirements to use ICT in all subjects, except physical education).

2. Pupils should be given opportunities to support their work by being taught to:
a) find things out from a variety of sources, selecting and synthesising the information to meet their needs and developing an ability to question its accuracy, bias and plausibility
b) develop their ideas using ICT tools to amend and refine their work and enhance its quality and accuracy
c) exchange and share information, both directly and through electronic media
d) review, modify and evaluate their work, reflecting critically on its quality, as it progresses.

Health and safety

1. This statement applies to science, design and technology, information and communication technology, art and design, and physical education.

2. When working with tools, equipment and materials, in practical activities and in different environments, including those that are unfamiliar, pupils should be taught:
a) about hazards, risks and risk control
b) to recognise hazards, assess consequent risks and take steps to control the risks to themselves and others
c) to use information to assess the immediate and cumulative risks
d) to manage their environment to ensure the health and safety of themselves and others
e) to explain the steps they take to control risks.

Attainment target 1: scientific enquiry

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Level 1
Pupils describe or respond appropriately to simple features of objects, living things and events they observe, communicating their findings in simple ways [for example, talking about their work, through drawings, simple charts].

Level 2
Pupils respond to suggestions about how to find things out and, with help, make their own suggestions about how to collect data to answer questions. They use simple texts, with help, to find information. They use simple equipment provided and make observations related to their task. They observe and compare objects, living things and events. They describe their observations using scientific vocabulary and record them, using simple tables when appropriate. They say whether what happened was what they expected.

Level 3
Pupils respond to suggestions and put forward their own ideas about how to find the answer to a question. They recognise why it is important to collect data to answer questions. They use simple texts to find information. They make relevant observations and measure quantities, such as length or mass, using a range of simple equipment. Where appropriate, they carry out a fair test with some help, recognising and explaining why it is fair. They record their observations in a variety of ways. They provide explanations for observations and for simple patterns in recorded measurements. They communicate in a scientific way what they have found out and suggest improvements in their work.

Level 4
Pupils recognise that scientific ideas are based on evidence. In their own investigative work, they decide on an appropriate approach [for example, using a fair test] to answer a question. Where appropriate, they describe, or show in the way they perform their task, how to vary one factor while keeping others the same. Where appropriate, they make predictions. They select information from sources provided for them. They select suitable equipment and make a series of observations and measurements that are adequate for the task. They record their observations, comparisons and measurements using tables and bar charts. They begin to plot points to form simple graphs, and use these graphs to point out and interpret patterns in their data. They begin to relate their conclusions to these patterns and to scientific knowledge and understanding, and to communicate them with appropriate scientific language. They suggest improvements in their work, giving reasons.

Level 5
Pupils describe how experimental evidence and creative thinking have been combined to provide a scientific explanation [for example, Jenner's work on vaccination at key stage 2, Lavoisier's work on burning at key stage 3]. When they try to answer a scientific question, they identify an appropriate approach. They select from a range of sources of information. When the investigation involves a fair test, they identify key factors to be considered. Where appropriate, they make predictions based on their scientific knowledge and understanding. They select apparatus for a range of tasks and plan to use it effectively. They make a series of observations, comparisons or measurements with precision appropriate to the task. They begin to repeat observations and measurements and to offer simple explanations for any differences they encounter. They record observations and measurements systematically and, where appropriate, present data as line graphs. They draw conclusions that are consistent with the evidence and begin to relate these to scientific knowledge and understanding. They make practical suggestions about how their working methods could be improved. They use appropriate scientific language and conventions to communicate quantitative and qualitative data.

Level 6
Pupils describe evidence for some accepted scientific ideas and explain how the interpretation of evidence by scientists leads to the development and acceptance of new ideas. In their own investigative work, they use scientific knowledge and understanding to identify an appropriate approach. They select and use sources of information effectively. They make enough measurements, comparisons and observations for the task. They measure a variety of quantities with precision, using instruments with fine-scale divisions. They choose scales for graphs and diagrams that enable them to show data and features effectively. They identify measurements and observations that do not fit the main pattern shown. They draw conclusions that are consistent with the evidence and use scientific knowledge and understanding to explain them. They make reasoned suggestions about how their working methods could be improved. They select and use appropriate methods for communicating qualitative and quantitative data using scientific language and conventions.

Level 7
Pupils describe some predictions based on scientific theories and give examples of the evidence collected to test these predictions. In their own work, they use scientific knowledge and understanding to decide on appropriate approaches to questions. They identify the key factors in complex contexts and in contexts in which variables cannot readily be controlled, and plan appropriate procedures. They synthesise information from a range of sources, and identify possible limitations in secondary data. They make systematic observations and measurements with precision, using a wide range of apparatus. They identify when they need to repeat measurements, comparisons and observations in order to obtain reliable data. Where appropriate, they represent data in graphs, using lines of best fit. They draw conclusions that are consistent with the evidence and explain these using scientific knowledge and understanding. They begin to consider whether the data they have collected are sufficient for the conclusions they have drawn. They communicate what they have done using a wide range of scientific and technical language and conventions, including symbols and flow diagrams.

Level 8
Pupils give examples of scientific explanations or models that have had to be changed in the light of additional scientific evidence. They evaluate and synthesise data from a range of sources. They recognise that investigating different kinds of scientific questions requires different strategies, and use scientific knowledge and understanding to select an appropriate strategy in their own work. They decide which observations are relevant in qualitative work and include suitable detail in their records. They decide the level of precision needed in comparisons or measurements, and collect data enabling them to test relationships between variables. They identify and begin to explain anomalous observations and measurements and allow for these when they draw graphs. They use scientific knowledge and understanding to draw conclusions from their evidence. They consider graphs and tables of results critically. They communicate findings and arguments using appropriate scientific language and conventions, showing awareness of a range of views.

Exceptional performance
Pupils give examples of scientific explanations and models that have been challenged by subsequent experiments and explain the significance of the evidence in modifying scientific theories. They evaluate and synthesise data from a range of sources. They recognise that investigating different kinds of scientific questions requires different strategies, and use scientific knowledge and understanding to select an appropriate strategy in their own work. They make records of relevant observations and comparisons, clearly identifying points of particular significance. They decide the level of precision needed in measurements and collect data that satisfy these requirements. They use their data to test relationships between variables. They identify and explain anomalous observations and measurements, allowing for these when they draw graphs. They use scientific knowledge and understanding to interpret trends and patterns and to draw conclusions from their evidence. They consider graphs and tables of results critically and give reasoned accounts of how they could collect additional evidence. They communicate findings and arguments using appropriate scientific language and conventions, showing their awareness of the degree of uncertainty and a range of alternative views.

Attainment target 2: life processes and living things

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Level 1
Pupils recognise and name external parts of the body [for example, head, arm] and of plants [for example, leaf, flower]. They communicate observations of a range of animals and plants in terms of features [for example, colour of coat, size of leaf]. They recognise and identify a range of common animals [for example, fly, goldfish, robin].

Level 2
Pupils use their knowledge about living things to describe the basic conditions [for example, a supply of food, water, air, light] that animals and plants need in order to survive. They recognise that living things grow and reproduce. They sort living things into groups, using simple features. They describe the basis for their groupings [for example, number of legs, shape of leaf]. They recognise that different living things are found in different places [for example, ponds, woods].

Level 3
Pupils use their knowledge and understanding of basic life processes [for example, growth, reproduction] when they describe differences between living and non-living things. They provide simple explanations for changes in living things [for example, diet affecting the health of humans or other animals, lack of light or water altering plant growth]. They identify ways in which an animal is suited to its environment [for example, a fish having fins to help it swim].

Level 4
Pupils demonstrate knowledge and understanding of life processes and living things drawn from the key stage 2 or key stage 3 programme of study. They use scientific names for some major organs of body systems [for example, the heart at key stage 2, the stomach at key stage 3] and identify the position of these organs in the human body. They identify organs [for example, stamen at key stage 2, stigma, root hairs at key stage 3] of different plants they observe. They use keys based on observable external features to help them to identify and group living things systematically. They recognise that feeding relationships exist between plants and animals in a habitat, and describe these relationships using food chains and terms [for example, predator and prey].

Level 5
Pupils demonstrate an increasing knowledge and understanding of life processes and living things drawn from the key stage 2 or key stage 3 programme of study. They describe the main functions of organs of the human body [for example, the heart at key stage 2, stomach at key stage 3], and of the plant [for example, the stamen at key stage 2, root hairs at key stage 3]. They explain how these functions are essential to the organism. They describe the main stages of the life cycles of humans and flowering plants and point out similarities. They recognise that there is a great variety of living things and understand the importance of classification. They explain that different organisms are found in different habitats because of differences in environmental factors [for example, the availability of light or water].

Level 6
Pupils use knowledge and understanding drawn from the key stage 3 programme of study to describe and explain life processes and features of living things. They use appropriate scientific terminology when they describe life processes [for example, respiration, photosynthesis] in animals and plants. They distinguish between related processes [for example, pollination, fertilisation]. They describe simple cell structure and identify differences between simple animal and plant cells. They describe some of the causes of variation between living things. They explain that the distribution and abundance of organisms in habitats are affected by environmental factors [for example, the availability of light or water].

Level 7
Pupils use knowledge and understanding of life processes and living things drawn from the key stage 3 programme of study to make links between life processes in animals and plants and the organ systems involved. They explain the processes of respiration and photosynthesis in terms of the main underlying chemical change. They use their knowledge of cell structure to explain how cells [for example, ovum, sperm, root hair] are adapted to their functions. They identify common variations between individuals, including some features [for example, eye colour] that are inherited and others [for example, height] that can also be affected by environmental factors. They construct models [for example, food webs, pyramids of numbers] to show feeding relationships, and explain how these relationships affect population size.

Level 8
Pupils demonstrate an extensive knowledge and understanding of life processes and living things drawn from the key stage 3 programme of study by describing and explaining how biological systems function. They relate the cellular structure of organs to the associated life processes [for example, the absorption of food in the digestive system, gas exchange in the lungs]. They recognise, predict and explain changes in biological systems [for example, the effect of increased carbon dioxide concentration on the growth of greenhouse crops, the consequences of smoking for organ systems]. They explain how characteristics can be inherited by individuals and apply their knowledge [for example, in relation to selective breeding]. They predict the short-term and long-term effects of environmental change on ecosystems and use their understanding of such systems to justify their predictions.

Exceptional performance
Pupils demonstrate both breadth and depth of knowledge and understanding drawn from the key stage 3 programme of study when they describe and explain how biological systems function. They recognise that organisms respond to change, and describe ways in which this is achieved. They relate their understanding of internal and external cellular structures to life processes [for example, the increased surface areas of cells in the digestive system]. They relate their understanding of cellular structure to inheritance and variation and explain how this leads to new varieties [for example, how genetic engineering is a modern form of selective breeding]. They recognise the importance of quantitative data [for example, related to populations in an environment] when they describe and explain patterns of change within an ecosystem.

Attainment target 3: materials and their properties

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Level 1
Pupils know about a range of properties [for example, texture, appearance] and communicate observations of materials in terms of these properties.

Level 2
Pupils identify a range of common materials and know about some of their properties. They describe similarities and differences between materials. They sort materials into groups and describe the basis for their groupings in everyday terms [for example, shininess, hardness, smoothness]. They describe ways in which some materials are changed by heating or cooling or by processes such as bending or stretching.

Level 3
Pupils use their knowledge and understanding of materials when they describe a variety of ways of sorting them into groups according to their properties. They explain simply why some materials are particularly suitable for specific purposes [for example, glass for windows, copper for electrical cables]. They recognise that some changes [for example, the freezing of water] can be reversed and some [for example, the baking of clay] cannot, and they classify changes in this way.

Level 4
Pupils demonstrate knowledge and understanding of materials and their properties drawn from the key stage 2 or key stage 3 programme of study. They describe differences between the properties of different materials and explain how these differences are used to classify substances [for example, as solids, liquids, gases at key stage 2, as acids, alkalis at key stage 3]. They describe some methods [for example, filtration, distillation] that are used to separate simple mixtures. They use scientific terms [for example, evaporation, condensation] to describe changes. They use knowledge about some reversible and irreversible changes to make simple predictions about whether other changes are reversible or not.

Level 5
Pupils demonstrate an increasing knowledge and understanding of materials and their properties drawn from the key stage 2 or key stage 3 programme of study. They describe some metallic properties [for example, good electrical conductivity] and use these properties to distinguish metals from other solids. They identify a range of contexts in which changes [for example, evaporation, condensation] take place. They use knowledge about how a specific mixture [for example, salt and water, sand and water] can be separated to suggest ways in which other similar mixtures might be separated.

Level 6
Pupils use knowledge and understanding of the nature and behaviour of materials drawn from the key stage 3 programme of study to describe chemical and physical changes, and how new materials can be made. They recognise that matter is made up of particles, and describe differences between the arrangement and movement of particles in solids, liquids and gases. They identify and describe similarities between some chemical reactions [for example, the reactions of acids with metals, the reactions of a variety of substances with oxygen]. They use word equations to summarise simple reactions. They relate changes of state to energy transfers in a range of contexts [for example, the formation of igneous rocks].

Level 7
Pupils use knowledge and understanding drawn from the key stage 3 programme of study to make links between the nature and behaviour of materials and the particles of which they are composed. They use the particle model of matter in explanations of phenomena [for example, changes of state]. They explain differences between elements, compounds and mixtures in terms of their constituent particles. They recognise that elements and compounds can be represented by symbols and formulae. They apply their knowledge of physical and chemical processes to explain the behaviour of materials in a variety of contexts [for example, the way in which natural limestone is changed through the action of rainwater, ways in which rocks are weathered]. They use patterns of reactivity [for example, those associated with a reactivity series of metals] to make predictions about other chemical reactions.

Level 8
Pupils demonstrate an extensive knowledge and understanding drawn from the key stage 3 programme of study, which they use to describe and explain the behaviour of, and changes to, materials. They use the particle model in a wide range of contexts. They describe what happens in a range of chemical reactions and classify some [for example, oxidation, neutralisation]. They represent common compounds by chemical formulae and use these formulae to form balanced symbol equations for reactions [for example, those of acids with metals, carbonates or oxides]. They apply their knowledge of patternsin chemical reactions to suggest how substances [for example, salts] could be made.

Exceptional performance
Pupils demonstrate both breadth and depth of knowledge and understanding drawn from the key stage 3 programme of study when they describe and explain the nature and behaviour of materials. They use particle theory in a wider range of contexts, recognising that differences in the properties of materials relate to the nature of the particles within them. They recognise, and give explanations for, examples of chemical behaviour that do not fit expected patterns. They routinely use balanced symbol equations for reactions. They interpret quantitative data about chemical reactions, suggesting explanations for patterns identified.

Attainment target 4: physical processes

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Level 1
Pupils communicate observations of changes in light, sound or movement that result from actions [for example, switching on a simple electrical circuit, pushing and pulling objects]. They recognise that sound and light come from a variety of sources and name some of these.

Level 2
Pupils know about a range of physical phenomena and recognise and describe similarities and differences associated with them. They compare the way in which devices [for example, bulbs] work in different electrical circuits. They compare the brightness or colour of lights, and the loudness or pitch of sounds. They compare the movement of different objects in terms of speed or direction.

Level 3
Pupils use their knowledge and understanding of physical phenomena to link cause and effect in simple explanations [for example, a bulb failing to light because of a break in an electrical circuit, the direction or speed of movement of an object changing because of a push or a pull]. They begin to make simple generalisations about physical phenomena [for example, explaining that sounds they hear become fainter the further they are from the source].

Level 4
Pupils demonstrate knowledge and understanding of physical processes drawn from the key stage 2 or key stage 3 programme of study. They describe and explain physical phenomena [for example, how a particular device may be connected to work in an electrical circuit, how the apparent position of the Sun changes over the course of a day]. They make generalisations about physical phenomena [for example, motion is affected by forces, including gravitational attraction, magnetic attraction and friction]. They use physical ideas to explain simple phenomena [for example, the formation of shadows, sounds being heard through a variety of materials].

Level 5
Pupils demonstrate knowledge and understanding of physical processes drawn from the key stage 2 or key stage 3 programme of study. They use ideas to explain how to make a range of changes [for example, altering the current in a circuit, altering the pitch or loudness of a sound]. They use some abstract ideas in descriptions of familiar phenomena [for example, objects are seen when light from them enters the eye at key stage 2, forces are balanced when an object is stationary at key stage 3]. They use simple models to explain effects that are caused by the movement of the Earth [for example, the length of a day or year].

Level 6
Pupils use and apply knowledge and understanding of physical processes drawn from the key stage 3 programme of study. They use abstract ideas in some descriptions and explanations [for example, electric current as a way of transferring energy, the sum of several forces determining changes in the direction or the speed of movement of an object, wind and waves as energy resources available for use]. They recognise, and can give examples of, the wide application of many physical concepts [for example, the transfer of energy by light, sound or electricity, the refraction and dispersion of light]. They give explanations of phenomena in which a number of factors have to be considered [for example, the relative brightness of planets and stars].

Level 7
Pupils use knowledge and understanding of physical processes drawn from the key stage 3 programme of study to make links between different phenomena. They make connections between electricity and magnetism when explaining phenomena [for example, the strength of electromagnets]. They use some quantitative definitions [for example, speed, pressure] and perform calculations, using the correct units. They apply abstract ideas in explanations of a range of physical phenomena [for example, the appearance of objects in different colours of light, the relationship between the frequency of vibration and the pitch of a sound, the role of gravitational attraction in determining the motion of bodies in the solar system, the dissipation of energy during energy transfers].

Level 8
Pupils demonstrate an extensive knowledge and understanding of the physical processes in the key stage 3 programme of study. They use models to describe and explain phenomena [for example, the magnetic field of an electromagnet, the passage of sound waves through a medium]. They use quantitative relationships between physical quantities in calculations that may involve more than one step. They offer detailed and sometimes quantitative interpretations of graphs [for example, speed-time graphs]. They consider ways of obtaining data [for example, of the solar system] and they use their knowledge of physical processes to explain patterns that they find. They consider physical phenomena from different perspectives [for example, relating the dissipation of energy during energy transfer to the need to conserve limited energy resources].

Exceptional performance
Pupils demonstrate both breadth and depth of knowledge and understanding of the physical processes in the key stage 3 programme of study when they describe and explain physical phenomena. They make effective use of a range of quantitative relationships between physical quantities. They understand how models [for example, the particle model] are useful in explaining physical phenomena [for example, how sweating causes cooling]. They apply their understanding of physical phenomena to a wide range of systems [for example, recognising the role of gravitational attraction in determining the movement of satellites, planets and stars]. They recognise the importance of quantitative data and make effective use of this when they consider questions such as energy efficiency.
