If your child is struggling at school and you have been told there is nothing more the school can do, a professional autism assessment can help change the conversation.

What Can Schools Do Without a Diagnosis?

More than most parents realise, and this is worth knowing before you start.

Schools in England use what the National Autistic Society calls a graduated approach: assess your child’s needs, plan support, put it in place, then review how well it is working. This happens through SEN Support and does not require a diagnosis. Most children with additional needs are supported this way without ever having an EHCP.

A diagnosis is not the gateway to support but it can strengthen the case when the usual support feels like it isn’t enough.

Where Does an Assessment Report Help?

Situation What the report contributes
School says needs are being met Independent clinical evidence that difficulties are neurological, not behavioural
Requesting an EHC needs assessment Professional documentation that current support is insufficient
Disagreement over the cause of difficulties A qualified clinician’s account, rather than parental description alone
Appealing a refused assessment Evidence to support your case at mediation or SEND Tribunal
Transition to secondary school A clear profile of needs for the new setting to work from
Exam access arrangements Supporting evidence for extra time or a separate room
  • School says needs are being met: independent clinical evidence that difficulties are neurological, not behavioural
  • Requesting an EHC needs assessment: professional documentation that current support is insufficient
  • Disagreement over the cause of difficulties: a qualified clinician’s account, rather than parental description alone
  • Appealing a refused assessment: evidence to support your case at mediation or SEND Tribunal
  • Transition to secondary school: a clear profile of needs for the new setting to work from
  • Exam access arrangements: supporting evidence for extra time or a separate room

How Does It Feed Into an EHCP?

An EHCP comes from an EHC needs assessment, and only the local authority can carry that out. A private autism assessment does not replace it. What your report does is form part of the evidence the local authority considers, alongside input from the school, you, and other professionals.

The NAS is clear that in law, the need for support through an EHCP does not have to be proven before an assessment takes place. The assessment exists to establish that. A diagnostic report strengthens your request but is not a prerequisite for making one.

What Are the Statutory Timescales?

Knowing these matters, because local authorities are bound by them:

  • 6 weeks for the local authority to decide whether to assess
  • 6 weeks for the assessment process itself
  • 20 weeks maximum from request to draft plan
  • 15 days for you to comment on a draft plan
  • 2 months to appeal a decision you disagree with
  • 12 months maximum between reviews of an existing plan

Who Can Request an EHC Needs Assessment?

Three groups can: the school, you as a parent or carer, and the young person themselves once they turn 16. You do not need the school’s agreement to make the request, though it can help to talk to them first.

If the local authority refuses, you have the right to appeal. The NAS notes that refusals are often driven by funding pressures rather than the merits of the case, so a refusal is not the end of the process.

What Should You Do First?

  • 1
    Meet the SENCO and ask what is currently in place under SEN Support
  • 2
    Keep notes on specific difficulties, when they occur, and what has been tried
  • 3
    Request an assessment in writing if current support is not working
  • 4
    Consider a private autism assessment if you want independent clinical evidence to strengthen your case

Frequently Asked Questions

No. EHCPs are awarded on the basis of need, not diagnosis, following a local authority needs assessment. A diagnosis provides evidence that strengthens the case considerably but does not guarantee the outcome.

A report from a suitably qualified clinician working to NICE guidelines carries the same clinical weight as an NHS one. Some local authorities scrutinise private reports more closely, which is why the clinician’s qualifications matter.

Yes. Parents and carers can request one directly, as can the school, or the young person once they are 16. You do not need the school’s permission.
