Autism

Autism is a neurodevelopmental difference — the NHS describes it as a difference in how the brain develops compared with people who are not autistic. It is lifelong, it is not an illness, and it is not something that is acquired or caused by parenting. Autistic people are described as differing in social communication and interaction, and in having patterns of behaviour, interests or activities that may be more focused, more repeated or more strongly attached to predictability.

That clinical description is accurate but thin. Autistic people describe it more usefully as a different way of processing information, sensation, language and social expectation — one that fits some environments very well and others very badly. A great deal of what looks like difficulty is the mismatch between a child and a setting, not a fixed property of the child.

These are things some autistic children experience. Many children who are not autistic do some of these too, and many autistic children do none of the more familiar ones.

• Communication that works differently: taking things literally, or finding small talk effortful, or preferring to communicate in writing or through a shared activity.
• Speech that developed differently — earlier, later, unusually formally, or not at all in the expected way.
• Strong preference for knowing what is happening, and real distress when plans change unexpectedly.
• Deep, sustained interests, sometimes with impressive expertise.
• Sensory experience that is more intense or less intense than expected — sound, light, texture, smell, clothing labels, food.
• Movement that helps regulate: rocking, pacing, hand movements, humming.
• Playing alongside rather than with, or preferring one friend, or preferring adults.
• Being fine all day at school and falling apart at home.
• Anxiety, especially around uncertainty, transitions and social demand.

Autism is often written about as a set of deficits, and that is both inaccurate and corrosive to read as a parent. Many autistic children bring precision, honesty, loyalty, deep knowledge, pattern-spotting, a low tolerance for unfairness, and the ability to concentrate on something that matters to them for far longer than most people can.

Interests are not a distraction from learning; they are frequently the most reliable route into it, and into friendship. A school that treats a child's interest as something to be rationed has usually misunderstood what it is for.

Some autistic children work extremely hard to appear to be coping — copying others, suppressing movement that helps them regulate, saying what seems expected. This is often called masking or camouflaging. It is well described by autistic people and increasingly discussed in research, and it has two consequences worth knowing.

• The child may be missed entirely, because school sees nothing of concern.
• The effort is expensive, and the cost is usually paid at home, in the evening or at weekends.

If school describes a child you do not recognise, that is information rather than a contradiction. Say so plainly and describe what you see.

Only a qualified clinical team can diagnose autism, usually through a multidisciplinary assessment following NICE CG128. Referral routes vary locally and often start with the GP, health visitor or school. Waits are long in many areas.

• A diagnosis can give a family and a child a way of understanding themselves, and can open some services.
• A diagnosis does not describe your child, their strengths, or what should happen in their classroom.
• Schools cannot diagnose autism, and should not tell you that they can.
• Support at school should not wait for the outcome of an assessment.
• Different autistic people and families prefer different language. "Autistic child" is widely preferred in the UK, but ask, and use what the child and family use.

• Anxiety that is persistent, or that is starting to shrink what your child will do.
• Reluctance to attend school, or attendance beginning to slip.
• Distress that is escalating in frequency or intensity.
• Changes in eating, sleeping or mood.
• Any concern about your child's safety or their own words about themselves.

Start with the class teacher and the SENDCO for school-based support. Your GP is the route for health concerns and for referral. NICE CG170 covers what NHS support and management should look like, and is a reasonable thing to reference if you feel a service is not responding.

   How recognition, referral and diagnostic assessment should work in England. Diagnosis is a multidisciplinary clinical process, not a school judgement.

   Plain-English NHS information, and clear that many autistic people will not show all the signs and that autism looks different in different people.

   Identifying and supporting the needs of autistic children and young people: a rapid evidence review (September 2025)

   DfE-commissioned review by UCL. Carries an explicit disclaimer that it is not an endorsement of the approaches described and does not reflect government policy.

   Neurodivergence Task and Finish Group: report — recommendations for mainstream education (February 2026)

   Independent report to DfE. Recommendations rather than statutory duties, organised around identification of strengths and needs, workforce, learning environments and accountability.

   SEND Code of Practice: 0 to 25 years (2015)

   Current statutory guidance: the graduated approach, the duty to involve children and families, and provision that follows identified need rather than diagnosis.

   Special Educational Needs in Mainstream Schools — guidance report (2020, updated 2021)

   High-quality teaching first, careful use of teaching assistants, and a warning against arrangements that separate pupils with SEND from their peers by default.

   Working together to improve school attendance (2022, statutory from 2024)

   Relevant where attendance is affected — expects barriers to be understood and support offered rather than attendance treated purely as compliance.

   Whole-school approach to wellbeing. Relevant because anxiety commonly sits alongside autism in school settings.
