What Is SEND? A Clear Guide for Parents and Teachers
Understanding special educational needs and disability, from classroom identification to formal plans
SEND stands for special educational needs and disability. It describes a wide range of ways a child might need extra help to learn, from difficulties with reading or number work to speech and language needs, autism, ADHD, or physical and sensory needs. About 1.7 million pupils in England (around 18.4% of pupils) were recorded as having special educational needs in 2024/25, according to the Department for Education, so it is a normal and common part of school life rather than an unusual exception.
What does SEND actually cover?
SEND is not one single category. In 2024/25, 14.2% of pupils were on SEN support and 5.3% had an education, health and care (EHC) plan, according to DfE figures. SEN support is the level most children receive, arranged and reviewed within school. An EHC plan is a legal document for children with more complex needs, setting out the specific provision a local authority must make.
Looked at over a whole school career rather than a single year, the picture is broader still. Almost four in ten children are recorded with SEND at some point between ages 5 and 16, based on longitudinal analysis from the Education Policy Institute. That reframes SEND as something many families encounter at some stage, not a fixed label that applies to a small, static group. For a fuller picture of how common this is, see record numbers of UK children with special educational needs.
How do schools identify a need?
Parents sometimes assume a diagnosis has to come first. It does not. Schools must not assume a diagnosis is required before identifying SEN or putting support in place, as set out in the SEND Code of Practice. In practice, identifying needs depends on teachers' observation and professional judgement working alongside data, not data alone, according to Education Endowment Foundation (EEF) guidance. A teacher noticing a child avoiding reading aloud, or struggling to keep up with instructions, is often where things start.
Identification is not always consistent, however. Research analysing records of around 540,000 primary-age children in England found that whether a child is identified with a learning difficulty can depend on school context, gender, family income and first language, as well as attainment, according to Durham University. The same research points out that fewer than 2% of pupils in England are identified as having a specific learning difficulty, against international estimates that 5 to 10% may be affected. This gap is one reason some children go unnoticed for longer than families would like. Our guide on undiagnosed SEN students in UK schools looks at this in more depth, alongside a practical guide to how schools identify learning difficulties.
What does support look like in the classroom?
Once a need is recognised, schools follow a structured cycle known as assess, plan, do and review, led by the class teacher and SENCo, normally reviewed with families at least three times a year, under the SEND Code of Practice. This is meant to be a genuine conversation with parents, not a one-off form.
The starting point for that support, according to EEF guidance, is high-quality inclusive teaching, placed at the heart of effective SEN provision in mainstream schools. That might mean clearer instructions, more visual support, structured routines, or extra time to process a task, delivered as part of everyday lessons rather than as a separate add-on. The stakes for getting this right early are real. By the end of primary school, the gap between pupils with identified SEND and their peers has, on average, been more than twice as wide as the gap linked to disadvantage, according to EEF analysis.
Why teacher-parent communication matters
Because reviews happen several times a year and rely on shared observation, keeping a simple, dated record of how a child is coping at home and school can make those conversations more productive. This is where tools like Milo can help parents note patterns between meetings, so that concerns are backed by specific examples rather than general worry, which supports the assess-plan-do-review cycle rather than replacing it.
When needs are more complex
Some children need more than classroom adjustments alone can provide. This is where an EHC needs assessment and, potentially, an EHC plan comes in, reserved for the most complex SEND cases, as explained in education care plans reserved for the most complex SEND cases. Many children, however, have their needs met through SEN support without ever needing an EHC plan; see SEN support without an EHCP for what that looks like in practice.
Schools also carry a legal duty here. They must take reasonable steps to avoid substantial disadvantage to disabled pupils caused by a provision, criterion or practice, or by the absence of an auxiliary aid, according to the Equality and Human Rights Commission. Read more in our guide to reasonable adjustments in UK schools. If parents disagree with a decision about an EHC plan, they can appeal to the First-tier Tribunal (SEND), with mediation available first, according to gov.uk.
Where to get independent advice
Every local authority funds a SEND information, advice and support service (SENDIASS), which families can contact for free, impartial guidance, according to the IASS Network. This can be particularly useful before a meeting, or if a parent is unsure what to ask for. Our practical piece on how to advocate for school support works through this step by step, and the glossary is a useful reference for the acronyms that tend to come up along the way.
SEND is best understood as a spectrum of support, built around a legal framework, professional judgement, and ongoing conversation between school and home. Whether a child is on SEN support, working towards an EHC plan, or somewhere in between, the same principle holds: identification is a starting point for support, not a label to be feared.

Notice patterns while you wait for answers
Milo is a Chrome extension that works inside Google Docs. It learns from how your child writes (typing patterns, pauses, corrections) and surfaces early indicators that may be worth exploring further. It provides adaptive writing support from the first session. No referral. No waiting list. No assessment fee.
