An autism assessment can seem daunting - but it's designed to give you answers.

Its purpose is to help you understand whether you or your child is autistic, and what support might make life feel less overwhelming.

During an assessment, a team of specialists gathers information about how you communicate, behave, and experience the world. They compare this with the core criteria for autism and build a picture of your strengths, challenges, and support needs. The process may take place over several sessions, sometimes in different settings, such as home, school, or work.

Here are some of the things clinicians may explore:

Communication and social interaction - How you communicate, understand others, and navigate social situations.

Repetitive behaviours and interests - Any routines, repetitive actions, or deep, focused interests that help you feel calm.

Sensory differences - How you respond to lights, sounds, textures, smells, or taste, and whether these affect daily life.

Daily functioning - Any struggles at school, work, or home, including relationships, organisation, or overwhelm.

Early development - Insights from someone who knew you well as a child, which help clinicians understand lifelong patterns.

Health and neurodivergence - Any physical or mental health conditions, learning differences, or other neurodivergences, such as ADHD.

Clinicians may also use structured activities or observations to understand how you respond to social situations or solve problems. Skills assessments may explore social communication, motor skills, sensory processing, and thinking styles.

Receiving your results 

You’ll receive a written report explaining the assessment findings and a support plan. A copy is usually sent to your GP, and you can ask for it to be shared with your child’s school if helpful.
