What is worth preparing for an adult autism assessment?

Preparation can help you remember examples and explain what support you need. It is not about learning the “right” answers. An adult autism assessment looks at your developmental history, experiences now and the ways they affect daily life. The service should tell you what information it needs and how the appointment will work.

You do not need a perfect timeline or a folder of evidence before seeking an assessment. Start with a few notes in your own words. If writing is difficult, ask the service whether you can share information another way.

Make a one-page note of real examples

Choose examples that show what happened, when it happened, how often it happens, and how it affects your daily life or the effort it takes. Include experiences that go well with support as well as situations that are hard. You can bring your note to the appointment or ask whether it can be sent beforehand.

  • Why you are seeking an assessment now, and what you hope to understand or get help with.
  • Early memories, if you have them, and current examples involving communication, relationships, routines, change, focused interests or sensory experiences.
  • Examples from more than one setting, such as home, education, work or social situations. Note any strategies you use and how much effort they take.
  • Strengths, helpful adjustments, other health or mental health concerns, and questions you want the clinician to answer.

Which records or people might help?

NICE recommends drawing on someone who knew you earlier in life or on documents about development where possible. That may add detail, but it does not mean you must contact a parent or produce school records. Tell the service what is available and what is not safe or possible to obtain.

  • School reports, earlier assessments or other records that describe your development, if you already have them.
  • A parent, relative or another person who knew you in childhood, if you are comfortable involving them.
  • A partner, friend or support person who can describe current experiences, if their perspective would be useful to you.

Questions to ask before the appointment

Services vary in format and referral rules. Contact yours in advance so you know what to expect and can request changes that make it easier to participate.

  • How many appointments are expected, how long are they, and will they be in person, by video or by phone?
  • Can I send notes in advance, bring a support person, take breaks or receive questions and information in a different format?
  • Which records, if any, would be useful? Is speaking with someone who knew me in childhood expected?
  • When and how will I receive feedback and a written report? What costs, referral rules or coverage apply?

What should you do during the assessment?

Describe your usual experience as honestly as you can, including things you have learned to manage or hide. It is fine to look at your notes, pause, ask for a question to be rephrased or say that you do not remember. If an example feels hard to explain, tell the clinician what part is uncertain.

An assessment can also consider ADHD, anxiety and other conditions that may overlap or coexist. You do not need to decide in advance which experience belongs to which condition; give the clinician the full picture and ask how they are interpreting it.

What should you ask after the assessment?

Ask for the conclusion in language you understand and a copy of the report. Check which strengths and support needs it describes, what follow-up is available, and who can use or receive the report. If the conclusion is uncertain or does not fit your experience, ask how it was reached and what options exist for further discussion.

This checklist helps you prepare for a conversation; it cannot tell you whether you are autistic. An online questionnaire can help you identify experiences to mention, but diagnosis depends on a full clinical assessment.
