Getting an Autism Diagnosis as an Adult What to Expect
Author: Caroline Goldsmith, Consulting Psychologist
A growing number of adults are seeking an autism assessment for the first time — often after years of feeling like they were different without quite knowing why, or after a child’s diagnosis prompted them to recognise similar patterns in themselves. If you’re considering this step, here’s an honest look at what the process actually involves.
Why So Many Adults Are Diagnosed Later in Life
Autism awareness and assessment tools have improved enormously over the past few decades, but they were historically built around how autism tends to present in young boys. Many adults — particularly women, and particularly those who developed strong coping or masking strategies — were simply never flagged as children, even though the underlying traits were there all along.
Common reasons adults pursue assessment include:
• Recognising similar traits after a child or family member is diagnosed
• A lifelong sense of not quite fitting social expectations, despite outward success
• Burnout from years of masking traits in work or social settings
• Curiosity and a desire for genuine self-understanding
What the Assessment Process Involves
An adult autism assessment is a structured process, not a single quick conversation. It typically includes:
A detailed clinical interview, covering developmental history (including childhood, where possible, often supported by input from a parent or old school reports if available), current daily functioning, social experiences, and sensory sensitivities.
Direct observation and structured tasks, using the same internationally recognised tools used in assessments for children — the ADOS-2 and ADI-R — adapted appropriately for an adult presentation.
A comprehensive written report, explaining not just whether the criteria for autism are met, but what that means specifically for you — your particular strengths, challenges, and practical recommendations. This is the kind of detailed, individualised report Caroline Goldsmith prepares for every adult client.
What Comes After a Diagnosis
For many adults, a diagnosis brings genuine relief — a framework that finally explains years of lived experience. Others find it brings up complicated emotions about earlier years spent without that understanding. Both reactions are completely normal.
Practically, an adult diagnosis can open the door to workplace accommodations, a clearer sense of which support strategies might actually help, and — for many people — simply the language to explain their own experience to themselves and others.
Quick answer: Is it too late to get diagnosed as an adult?
No. Diagnosis is valuable at any age, and many adults describe significant benefit from finally understanding a lifelong pattern.
Quick answer: Do I need a childhood diagnosis history to be assessed as an adult?
No, though information about childhood development (even informally, from memory or family input) can strengthen the assessment. It is not a requirement.
