Thank you for clarifying how the school are supporting your daughter, this is fantastic to hear that she is already receiving some very helpful support. It is reassuring and shows that they are responding to her needs rather than waiting for an assessment to take place, which as you are aware can take a very long time.
In terms of whether a formal diagnosis might bring additional support, this can vary quite a lot depending on your local service provision. For some families, post-diagnostic support is relatively limited; for others, it can open doors that are harder to access without a diagnosis.
From health services perspective, a diagnosis may lead to:
- Access to post-diagnostic psychoeducation (sometimes group-based, sometimes individual), helping both parents and young people understand autism/ ADHD and how it affects them and how to meet a persons needs with a diagnosis.
- Clearer pathways into neurodevelopmentally informed mental health support (e.g. autism-adapted therapy, CAMHS input where mental health needs are present).
However, it’s important to be honest that in many areas, NHS post-diagnostic support is quite variable and sometimes minimal. Some families receive only a diagnostic report and signposting. This doesn’t mean a diagnosis lacks value, but it does mean expectations need to be realistic and shaped by what your local area offers.
Within education, a diagnosis can:
- Strengthen the case for ongoing and consistent reasonable adjustments, particularly as demands increase over time
- Support applications for exam access arrangements and any transition planning (e.g. progression through school years, different teachers, move to sixth form/ college etc.)
- Help if an EHCP is being considered in the future (though a diagnosis alone doesn’t guarantee one)
That said, as Olivia mentioned in her previous reply, schools are legally required to meet needs under SEN Support without a diagnosis, and it sounds like your daughter’s school is already doing this well.
Additionally, as you noted, having a diagnosis can also help your daughter make sense of her experiences, reduce any self-blame experienced, and support her mental health. This can be especially important when coping with overwhelming feelings or self-harm, giving her a framework for understanding her emotional and sensory responses.
You’ve raised a really important point about your daughter’s mental health and self-harm. For many young people, particularly autistic young people, self-harm can function as a way of coping with overwhelming emotional, sensory, or cognitive states. Therapy can help her to understand why her experiences feel so intense, and building alternative ways to regulate and express distress. A diagnosis can sometimes support that self-understanding, but this therapeutic work is important and can begin regardless of diagnosis and in line with when she feels ready.
In terms of advocacy and navigating education, if you haven't already I would strongly recommend contacting SENDIASS (Special Educational Needs and Disability Information, Advice and Support Service). SENDIASS services are independent, free, and available in every local authority. Many parents find SENDIASS invaluable. They can:
- Help you understand your daughter’s rights around SEN support
- Support you in meetings with school
- Advise on EHCP processes if that ever becomes relevant
- Provide guidance and reassurance around advocating without needing a diagnosis
Ultimately, it’s absolutely ok to hold both positions at once: to be grateful for the support your daughter is receiving now and still consider a formal diagnosis for longer-term clarity, protection, and self-understanding. You’re clearly advocating thoughtfully and compassionately for your daughter, and that in itself is a major protective factor for her.
Please do continue to ask questions here. You’re not alone in this, we recognise it can feel very isolating at times.
With best wishes,
Dr Imogen Thynne
