This guide covers England. It is information, not medical advice. Every autistic child is different, so treat this as a starting point rather than a description of any one child.
What autism is, in plain terms
Autism is a difference in how a person communicates, behaves and experiences the world. Autistic people may find it harder to read what others mean, may prefer routine and find changes difficult, and may experience sights, sounds and other senses more intensely. Every autistic person is different, and many will not show all the common signs.
One point matters more than any other. Autism is not an illness, and it does not need to be fixed or cured. Autistic children thrive when they are understood and supported, not when they are pushed to behave more like everyone else. Autism is lifelong and present from birth, and it can be recognised in some children from a very young age.
Support in school is based on a child's needs, not on a diagnostic label. Your child does not need a confirmed diagnosis before the school can start putting help in place.
Assessment routes can be long, so this really matters. A waiting list is not a reason to wait for support.
Getting an assessment, if you want one
If you think your child may be autistic, the first step is to talk to someone. You can speak to your GP, a health visitor for a child under five, or the SENCO at your child's school, and they can refer for an autism assessment. If a referral is accepted, it can take a few months or longer to get seen. That is precisely why school support should run alongside, not behind, any assessment.
What your child is entitled to
Two duties sit behind support at school. First, schools must make reasonable adjustments for disabled pupils and must not discriminate against them, and autism can count as a disability. Second, where a child has special educational needs, they should receive SEN support, the extra help a school arranges from its own resources. If needs are more complex, an EHC plan can set out provision that the local authority has a legal duty to deliver.
In practice, support for an autistic child often includes:
- Predictable routines, and warning before changes or transitions
- Visual supports, timetables and clear, literal instructions
- A quiet space to go to when things become overwhelming
- Adjustments for sensory needs, such as noise or busy corridors
- Support at unstructured times like break and lunch
- Help with social situations, communicated in a way that suits the child
Bring what you see at home
You see a side of your child that school does not. Bringing that to a meeting makes the support far better matched. It helps to note:
- What triggers distress, and what helps your child settle
- How your child communicates, and what they find hard to express
- Sensory likes and dislikes
- Examples from school days, with dates, and what happened afterwards at home
If school support is not enough
If your child needs more than SEN support can provide, you can ask your local authority to carry out an EHC needs assessment, which can lead to an EHC plan. You do not need a diagnosis to make that request. If the authority refuses to assess, you can appeal to the SEND Tribunal. We cover the plan and a refusal in separate guides.
Parents of autistic children often become expert translators, between home and school, between their child and a system that was not built around them. The school and the local authority know the processes. You are learning them while holding a great deal else together.
AI can help with the information side of that load: understanding terms, getting your observations into a clear form, and preparing for meetings. It does not assess your child, and it is not a replacement for your GP, a specialist assessment team or the SENCO.
What AI could help with
- Explain SEND terms and what a SENCO and an EHC plan do
- Turn your observations into a clear profile of how your child experiences school
- Draft questions for the SENCO or the assessment team
- Organise examples and correspondence into a simple record
- Help you write a calm request for an EHC needs assessment
- Summarise a report into plain English so you can follow it
Do not use AI to diagnose your child or to decide whether they are autistic, and do not treat online checklists as an assessment. AI can also invent facts, figures and studies while sounding certain. Use it to organise your own information and understand the process. Use your GP and the assessment team for anything clinical, and official guidance for the position on support.
A better way to prompt it
That keeps AI where it earns its place, helping you prepare and explain, while the assessment and the teaching stay with the people qualified to provide them.
Where to get proper help
- Your child's SENCO, for SEN support in school
- Your GP or health visitor, towards an assessment
- Your local SEND Information, Advice and Support Service (SENDIASS)
- IPSEA (Independent Provider of Special Education Advice), for free legally-based advice
- EHCP Expert, to help guide you through an EHC needs assessment if you go that route

Common questions
Does my child need an autism diagnosis to get support at school?
No. Support in school is based on need, not on a diagnosis. You can talk to the SENCO and ask for SEN support at any time, including while you are waiting for an assessment.
Is autism an illness that needs curing?
No. Autism is not an illness and does not need to be cured. It is a lifelong difference in how a person communicates and experiences the world, and children do best when they are understood and supported.
Who can refer my child for an autism assessment?
You can speak to your GP, a health visitor for a child under 5, or the SENCO at your child's school, and they can refer for an assessment. It can take a few months or longer.
What is my child entitled to at school?
Schools must make reasonable adjustments for disabled pupils and should provide SEN support where a child needs it. If needs are more complex, an EHC plan sets out support that the local authority has a duty to deliver.
