What Happens After an Autism Diagnosis?

People respond to an autism diagnosis in very different ways. Some feel relief, or a sense that things finally make sense. Some feel validated after years of wondering. Others feel uncertain, sad, unsettled, or all of these things at once — and feelings often change over the following weeks and months.

There is no correct way to respond, and no timetable to keep to. It can take a while to work out what a diagnosis means for you personally, or for your child and your family, and that is entirely normal.

Autism Support Wales is an independent information and directory service. We do not carry out assessments, provide diagnoses or give clinical advice. This page is general information to help you think about what might come next.

The professional or provider who carried out the assessment should discuss the outcome with you and explain how they reached it. In most cases you will also receive a written report setting out what was assessed and what was concluded.

Once you have the report, it can help to:

• Read the report in your own time, in whatever way suits you
• Write down questions as they occur to you
• Check that factual information about you or your child is accurate
• Ask for any unfamiliar language or terminology to be explained
• Ask for clarification of any recommendations you are unsure about
• Keep the report somewhere secure, along with any related correspondence
• Ask who to contact if you have follow-up questions later

If you are still at an earlier stage, or want to understand how the process works, see our guide to getting an autism assessment in Wales.

For many people, a diagnosis is a useful framework rather than a change. It can help make sense of experiences that were previously confusing, and give language for strengths, sensory needs, communication preferences and the situations where support or reasonable adjustments would help.

A diagnosis does not change who you are. You are the same person you were before the appointment — with more information about how you experience the world.

Autistic people are not all alike. Two people with the same diagnosis can have very different strengths, sensory experiences, communication styles and support needs, so it is worth focusing on what is true for you or your child rather than on general descriptions.

Not receiving a diagnosis can feel deflating, particularly after a long wait. It does not mean that the experiences or difficulties you described are not real, or that you were wrong to seek an assessment. It means that, on the information considered, the professionals did not conclude that the diagnostic criteria were met.

It is reasonable to ask:

• Why were the diagnostic criteria not considered to be met?
• Was another explanation identified for the experiences discussed?
• Might further assessment be appropriate at some point?
• What support or adjustments could still help?
• Can I receive a copy of the report?
• What options are available if I disagree with the outcome?

We cannot say whether a different assessment would reach a different conclusion, and nobody can promise a particular outcome. What often matters most in practice is identifying the support and adjustments that would help you day to day, whether or not a diagnosis is given.

Deciding whether to share a diagnosis is personal, and you do not have to tell anyone simply because you have a report. The main exception is practical: parents and carers often need to share relevant information in order to arrange support for a child.

Before sharing, it can help to think about two things — what information you are comfortable sharing, and what support or adjustment you are actually asking for. Often you need far less detail than you might expect.

Parents and carers can usually arrange a conversation with the school or college to talk through the assessment report, the learner's needs and what support would help. Ask the setting who is best placed to have that discussion.

Support should be based on the individual learner's needs rather than on a diagnosis alone, so it helps to describe what your child finds difficult and what already works well for them. Topics families often discuss include:

• Communication preferences
• Sensory needs
• Predictable routines and preparation for change
• Emotional regulation
• Breaks or access to a quieter space
• Classroom arrangements, such as seating
• Support during unstructured times, like breaks and lunchtimes
• Transition planning between classes, years or settings

Processes and terminology differ between settings, so ask the school or college to explain how they plan and review support locally. For more on this area, see education and school support.

Many autistic employees find that a small number of practical adjustments make a significant difference. What helps depends on the individual and on the role. Examples that people commonly ask about include:

• Clear written instructions
• More predictable communication
• Advance notice of changes
• Adjustments to lighting or noise
• A quieter workspace
• Structured meetings with agendas
• Flexible working arrangements where appropriate
• Additional processing time

Adjustments are individual and need to be discussed with your employer, who will consider what is workable in your role and organisation. We cannot guarantee that a particular adjustment will be agreed. It often helps to be specific about the difficulty and the change that would address it, rather than asking in general terms.

Where it feels relevant, it can be worth discussing your needs with your GP or another healthcare professional involved in your care, so that appointments and care can be adapted. Topics people sometimes raise include:

• Communication preferences
• Sensory needs during appointments
• Anxiety or mental health
• Sleep
• Eating or nutrition concerns
• Other physical or mental health needs

Autism itself is not a mental illness and is not something to be treated or cured. Autistic people can, however, also experience mental health difficulties — and those difficulties deserve support in their own right.

Support after diagnosis varies across Wales. What is available may depend on age, where you live, eligibility criteria and which local services exist, so we cannot tell you what will be offered to you specifically.

Support that exists in some form includes:

• Information and education about autism
• Peer-support groups
• Family or parent support
• Autism-informed counselling or therapy
• Help with communication or sensory needs
• Education or employment support
• Independent living support
• Benefits or financial guidance where eligible
• Support from local or national charities

Nobody needs all of this. Many people need very little, or only at particular points in life. You might also find our pages on family support, post-diagnostic support and therapists and professionals useful.

Some people find it helpful to write a short personal summary they can draw on when explaining their needs at school, at work or in healthcare settings. This is an optional practical tool — not a medical treatment plan, and not something anyone requires you to produce.

You might note:

Children and young people take their cue from the adults around them, so how a diagnosis is talked about matters as much as what is said. Practical things that help:

• Explain autism in an age-appropriate and positive way
• Focus on your child's individual strengths and needs
• Give your child time to ask questions, now and later
• Avoid presenting the diagnosis as something shameful or secret
• Share relevant information with school where it helps them provide support
• Review the recommendations in the assessment report together
• Listen to your child's preferences about what is shared and with whom
• Seek support for siblings or other family members where that would help

How and when to tell a child depends on their age, understanding and preferences — there is no single right approach, and it is usually a series of conversations rather than one. It is worth thinking with your child, where they are able to take part, about what is shared and with whom.
