Complete glossary of SEND acronyms for UK teachers. Covers EHCP, APDR, CAMHS, EP, SALT, SENCO, and 80+ abbreviations with plain English explanations...
SEND documentation is saturated with acronyms. A newly qualified teacher reading their first EHCP will encounter SALT, OT, EP, CAMHS, SEMH, and dozens more, often with no glossary attached. Annual review paperwork assumes you already know what APDR means. Referral forms reference TAC, TAF, and MASH without explanation. This guide explains every abbreviation you will meet in UK special educational needs provision. They are grouped by category and explained in plain English with classroom context.


These twenty acronyms appear in virtually every SEND document, meeting, and conversation in UK schools. If you learn nothing else from this guide, learn these.
A Year 3 class teacher receiving their first EHCP transfer file will see most of these within the first two pages. Knowing them before your first annual review meeting means you can focus on the child rather than decoding the paperwork.

For example, a typical sentence in an EHCP might read: "Following APDR, the SENCO consulted with the EP and SALT, who recommended QFT adjustments alongside a targeted SEMH intervention delivered by the LSA." That single sentence contains seven acronyms. With the table above, you can now read it fluently.
These acronyms describe specific conditions, diagnoses, or categories of need. You will see them on SEN registers, in EP reports, on CAMHS referral forms, and throughout EHCPs.
When a parent tells you their child has a diagnosis of DCD, or an EP report arrives referencing SpLD, knowing what these mean (and what they look like in your classroom) is essential for planning effective differentiation.

For example, a Year 5 pupil's SEN register entry might list "ASC, SpLD (dyslexia), SEMH." This tells you the child is autistic, has a specific literacy difficulty, and experiences social or emotional challenges. Each acronym points you towards a different set of classroom strategies.
These acronyms relate to how schools identify needs, plan support, and track progress. You will encounter them during provision mapping, SENCO meetings, and when writing or reviewing support plans.
A practical example: when your SENCO asks you to "update the APDR cycle on the IEP using SMART targets before the TAC meeting," they are asking you to review the assess, plan, do, review cycle, update the individual education plan with specific and measurable targets, and have it ready for the multi-agency team meeting.
Acronym
Full Term
Explanation and Context
APDR
Assess, Plan, Do, Review
The graduated approach required by the COP. You assess the pupil's needs, plan the intervention, deliver it, then review its impact. The cycle repeats termly or more frequently.
IEP
Individual Education Plan
A short document with 3 or 4 SMART targets. Some schools now use "SEN Support Plans" or "Pupil Profiles" instead, but IEP remains widely understood.
IBP
Individual Behaviour Plan
Similar to an IEP but focused specifically on behaviour targets and strategies. Common for pupils with SEMH needs.
PSP
Pastoral Support Programme
A structured 16-week programme for pupils at risk of permanent exclusion. Involves multi-agency review meetings.
PEP
Personal Education Plan
A statutory plan for looked after children (CiC/LAC), reviewed termly. Covers educational targets and how Pupil Premium Plus funding is used.
CAF/EHA
Common Assessment Framework / Early Help Assessment
A multi-agency assessment for families needing support from more than one service. EHA has replaced CAF in most areas, but both terms are still used.
TAC/TAF
Team Around the Child / Team Around the Family
A multi-agency meeting bringing together all professionals involved with a child or family. You may be asked to attend and provide classroom evidence.
EHCA
Education, Health and Care Needs Assessment
The formal assessment process that may lead to an EHCP. The LA has 6 weeks to decide whether to assess, then 20 weeks to complete the process.
SEN Support
SEN Support (K code)
The category for pupils with identified SEND who receive support through the graduated approach but do not have an EHCP. Recorded as "K" on the school census.
SA / SA+
School Action / School Action Plus
Legacy terms (pre-2014) for levels of SEN support. SA meant school-led intervention; SA+ meant external specialists were involved. Now replaced by "SEN Support."
P Levels/P Scales
Performance Levels
Assessment criteria (P1 to P8) used for pupils working below the level of the national curriculum. Largely replaced by the Pre-Key Stage Standards but still referenced in some settings.
When a multi-agency meeting is called, the invite list reads like an alphabet soup. Knowing who each professional is and when they typically get involved helps you prepare the right evidence and ask the right questions.
For example, if a Year 2 pupil struggles with pencil grip and letter formation, the right professional is an OT, not a SALT. If a Year 6 pupil won't speak in class but speaks freely at home, refer them to a SALT with selective mutism expertise, not an EP.

NHS services providing diagnosis and treatment for mental health conditions. Involved for anxiety, depression, self-harm, eating disorders, and neurodevelopmental assessments (ADHD, autism).
CYPMHS
Children and Young People's Mental Health Services
The updated name for CAMHS in many areas. Same service, different branding. Check your local area's terminology.
Portage
Portage Home Visiting Service
An early intervention service for pre-school children with SEND. Portage workers visit families at home to teach developmental skills through play. Involved from birth to school entry.
SENDIASS
SEND Information, Advice and Support Service

HI Teacher
Hearing Impairment Teacher
A qualified teacher of the deaf. Advises on hearing technology, acoustic environments, and communication strategies. Mandatory involvement for pupils with HI.

These acronyms reference the legal framework underpinning SEND provision. When a parent quotes "the COP" or a solicitor references "the CFA 2014," they are pointing to specific legal duties. Understanding the shorthand helps you respond with confidence.
For example, if a parent mentions their child's rights under the Equality Act, they mean schools must make reasonable adjustments under EA 2010. Knowing this means you can immediately check whether your school has documented the adjustments in place and evidenced the decision-making process.

APDR stands for Assess, Plan, Do, Review. It is the graduated approach cycle used in UK schools to identify and support pupils with special educational needs. Teachers use this framework to set specific targets, use strategies, and measure the impact of those interventions over time.
Quality First Teaching involves providing high quality inclusive classroom instruction that meets the needs of all learners before additional interventions are applied. Teachers use this by using clear visual aids, scaffolding tasks, checking for understanding frequently, and adapting resources. This approach ensures that many potential barriers to learning are removed during regular lessons.
SEN refers specifically to Special Educational Needs and focuses solely on the educational requirements of a child. SEND encompasses Special Educational Needs and Disabilities to include the medical or physical disability element. Older documents often use SEN. Modern guidance and local authority paperwork now use SEND to ensure all areas of need are recognised.
A frequent mistake is focusing entirely on the funding allocation rather than the specific provision recommendations. Teachers sometimes miss the subtle distinctions between different professional recommendations from external specialists. Reading past the acronyms without understanding the specific strategies required can lead to ineffective classroom support and unmet legal obligations.
Special educational needs documentation is filled with specific terminology that carries legal and practical weight. Understanding these abbreviations allows teachers to interpret reports accurately and use the correct support strategies immediately. This clear comprehension improves communication with external agencies and ensures classroom provision is precise and effective.
Research indicates that clear communication between teachers, parents, and specialists significantly improves pupil outcomes. When teachers understand and correctly apply the strategies outlined in professional reports, interventions are more likely to succeed. Accurate documentation ensures that statutory obligations are met and that resources are targeted exactly where the child needs them most.
Print the quick reference wall chart above and pin it next to your desk this week. The next time you receive an EHCP, an EP report, or an invite to a TAC meeting, you will have every acronym at your fingertips. Start with the essential 20, then use the categorised tables to build your knowledge as each acronym appears in your work. The fastest way to learn them is not memorisation; it is encountering them in real documents with this guide open beside you.
These five resources provide the official definitions and frameworks behind the acronyms in this guide.
SEND Code of Practice: 0 to 25 Years (DfE, 2015)
The statutory guidance underpinning all SEND provision in England. Every acronym in the assessment and legislation sections traces back to this document. Essential reading for any teacher working with pupils on the SEN register.
Nasen SEND Glossary
A searchable glossary maintained by the National Association for Special Educational Needs. Useful as a quick-check companion to this guide when you encounter an unfamiliar term in a meeting or document.
Council for Disabled Children: Resources for Practitioners
Practical guides on EHCPs, the graduated approach, and working with families. Particularly strong on translating legislation into classroom action.
The Communication Trust: Resources for Schools
Focused on speech, language, and communication needs. Covers SALT referral pathways, AAC systems, and classroom strategies for pupils with communication difficulties.
DfE Teachers' Standards (2011, updated 2021)
Standard 5 requires teachers to "adapt teaching to respond to the strengths and needs of all pupils," including those with SEND. Understanding the acronyms in this guide is a prerequisite for meeting that standard in practice.
External References: EEF: Special Educational Needs and Disabilities Toolkit | SEND Code of Practice: 0 to 25 Years (DfE)
SEND documentation is saturated with acronyms. A newly qualified teacher reading their first EHCP will encounter SALT, OT, EP, CAMHS, SEMH, and dozens more, often with no glossary attached. Annual review paperwork assumes you already know what APDR means. Referral forms reference TAC, TAF, and MASH without explanation. This guide explains every abbreviation you will meet in UK special educational needs provision. They are grouped by category and explained in plain English with classroom context.


These twenty acronyms appear in virtually every SEND document, meeting, and conversation in UK schools. If you learn nothing else from this guide, learn these.
A Year 3 class teacher receiving their first EHCP transfer file will see most of these within the first two pages. Knowing them before your first annual review meeting means you can focus on the child rather than decoding the paperwork.

For example, a Year 5 pupil's SEN register entry might list "ASC, SpLD (dyslexia), SEMH." This tells you the child is autistic, has a specific literacy difficulty, and experiences social or emotional challenges. Each acronym points you towards a different set of classroom strategies.
These acronyms relate to how schools identify needs, plan support, and track progress. You will encounter them during provision mapping, SENCO meetings, and when writing or reviewing support plans.
A practical example: when your SENCO asks you to "update the APDR cycle on the IEP using SMART targets before the TAC meeting," they are asking you to review the assess, plan, do, review cycle, update the individual education plan with specific and measurable targets, and have it ready for the multi-agency team meeting.
Acronym
Full Term
Explanation and Context
APDR
Assess, Plan, Do, Review
The graduated approach required by the COP. You assess the pupil's needs, plan the intervention, deliver it, then review its impact. The cycle repeats termly or more frequently.
IEP
Individual Education Plan
A short document with 3 or 4 SMART targets. Some schools now use "SEN Support Plans" or "Pupil Profiles" instead, but IEP remains widely understood.
IBP
Individual Behaviour Plan
Similar to an IEP but focused specifically on behaviour targets and strategies. Common for pupils with SEMH needs.
PSP
Pastoral Support Programme
A structured 16-week programme for pupils at risk of permanent exclusion. Involves multi-agency review meetings.
PEP
Personal Education Plan
A statutory plan for looked after children (CiC/LAC), reviewed termly. Covers educational targets and how Pupil Premium Plus funding is used.
CAF/EHA
Common Assessment Framework / Early Help Assessment
A multi-agency assessment for families needing support from more than one service. EHA has replaced CAF in most areas, but both terms are still used.
TAC/TAF
Team Around the Child / Team Around the Family
A multi-agency meeting bringing together all professionals involved with a child or family. You may be asked to attend and provide classroom evidence.
EHCA
Education, Health and Care Needs Assessment
The formal assessment process that may lead to an EHCP. The LA has 6 weeks to decide whether to assess, then 20 weeks to complete the process.
SEN Support
SEN Support (K code)
The category for pupils with identified SEND who receive support through the graduated approach but do not have an EHCP. Recorded as "K" on the school census.
SA / SA+
School Action / School Action Plus
Legacy terms (pre-2014) for levels of SEN support. SA meant school-led intervention; SA+ meant external specialists were involved. Now replaced by "SEN Support."
P Levels/P Scales
Performance Levels
Assessment criteria (P1 to P8) used for pupils working below the level of the national curriculum. Largely replaced by the Pre-Key Stage Standards but still referenced in some settings.
When a multi-agency meeting is called, the invite list reads like an alphabet soup. Knowing who each professional is and when they typically get involved helps you prepare the right evidence and ask the right questions.
For example, if a Year 2 pupil struggles with pencil grip and letter formation, the right professional is an OT, not a SALT. If a Year 6 pupil won't speak in class but speaks freely at home, refer them to a SALT with selective mutism expertise, not an EP.
Acronym

Role and When They Get Involved
EP
Educational Psychologist
Assesses cognitive ability, learning barriers, and emotional needs. Involved during EHCA, complex cases, and when school-level interventions have not produced sufficient progress.
SALT/SLT

OT
Occupational Therapist
Supports fine and gross motor skills, sensory processing, and daily living skills. Involved for handwriting difficulties, sensory needs, and physical access to the curriculum.
CAMHS
Child and Adolescent Mental Health Services
NHS services providing diagnosis and treatment for mental health conditions. Involved for anxiety, depression, self-harm, eating disorders, and neurodevelopmental assessments (ADHD, autism).
CYPMHS
Children and Young People's Mental Health Services
The updated name for CAMHS in many areas. Same service, different branding. Check your local area's terminology.
Portage
Portage Home Visiting Service
An early intervention service for pre-school children with SEND. Portage workers visit families at home to teach developmental skills through play. Involved from birth to school entry.
SENDIASS
SEND Information, Advice and Support Service

The senior staff member responsible for safeguarding in your school. Your first point of contact for any child protection concern. Often overlaps with the SENCO role in smaller schools.
MASH
Multi-Agency Safeguarding Hub
A single point of contact where police, social care, health, and education share information on safeguarding referrals. You contact MASH when making a safeguarding referral.
AIO
Attendance Improvement Officer

HI Teacher
Hearing Impairment Teacher
A qualified teacher of the deaf. Advises on hearing technology, acoustic environments, and communication strategies. Mandatory involvement for pupils with HI.

These acronyms reference the legal framework underpinning SEND provision. When a parent quotes "the COP" or a solicitor references "the CFA 2014," they are pointing to specific legal duties. Understanding the shorthand helps you respond with confidence.
For example, if a parent mentions their child's rights under the Equality Act, they mean schools must make reasonable adjustments under EA 2010. Knowing this means you can immediately check whether your school has documented the adjustments in place and evidenced the decision-making process.

APDR stands for Assess, Plan, Do, Review. It is the graduated approach cycle used in UK schools to identify and support pupils with special educational needs. Teachers use this framework to set specific targets, use strategies, and measure the impact of those interventions over time.
Quality First Teaching involves providing high quality inclusive classroom instruction that meets the needs of all learners before additional interventions are applied. Teachers use this by using clear visual aids, scaffolding tasks, checking for understanding frequently, and adapting resources. This approach ensures that many potential barriers to learning are removed during regular lessons.
SEN refers specifically to Special Educational Needs and focuses solely on the educational requirements of a child. SEND encompasses Special Educational Needs and Disabilities to include the medical or physical disability element. Older documents often use SEN. Modern guidance and local authority paperwork now use SEND to ensure all areas of need are recognised.
A frequent mistake is focusing entirely on the funding allocation rather than the specific provision recommendations. Teachers sometimes miss the subtle distinctions between different professional recommendations from external specialists. Reading past the acronyms without understanding the specific strategies required can lead to ineffective classroom support and unmet legal obligations.
Special educational needs documentation is filled with specific terminology that carries legal and practical weight. Understanding these abbreviations allows teachers to interpret reports accurately and use the correct support strategies immediately. This clear comprehension improves communication with external agencies and ensures classroom provision is precise and effective.
Research indicates that clear communication between teachers, parents, and specialists significantly improves pupil outcomes. When teachers understand and correctly apply the strategies outlined in professional reports, interventions are more likely to succeed. Accurate documentation ensures that statutory obligations are met and that resources are targeted exactly where the child needs them most.
Print the quick reference wall chart above and pin it next to your desk this week. The next time you receive an EHCP, an EP report, or an invite to a TAC meeting, you will have every acronym at your fingertips. Start with the essential 20, then use the categorised tables to build your knowledge as each acronym appears in your work. The fastest way to learn them is not memorisation; it is encountering them in real documents with this guide open beside you.
These five resources provide the official definitions and frameworks behind the acronyms in this guide.
SEND Code of Practice: 0 to 25 Years (DfE, 2015)
The statutory guidance underpinning all SEND provision in England. Every acronym in the assessment and legislation sections traces back to this document. Essential reading for any teacher working with pupils on the SEN register.
