Autism Assessment

ADOS-based autism diagnostic assessments led by our psychology team, with practical reports to guide next steps and support planning.

GRS psychologists conduct comprehensive autism diagnostic assessments using the Autism Diagnostic Observation Schedule (ADOS-2) alongside developmental history, standardised questionnaires, and clinical observation. A formal diagnosis can be an important step toward accessing the right supports, whether that's NDIS funding, school-based accommodations, or a clearer understanding of a person's needs within their family. We work with children, adolescents, and adults, tailoring the assessment process to the person's age and presentation.

What to Expect

The process usually begins with an intake conversation to gather developmental and family history, followed by one or more assessment sessions involving structured observation and, where relevant, input from parents, carers, teachers, or other people who know the person well. Once complete, our psychologists prepare a detailed report outlining the assessment findings, a diagnostic outcome where appropriate, and practical, individualised recommendations for support — whether that's therapy, educational adjustments, or referrals to other specialists. We take the time to talk through the results with families rather than simply handing over a report.

Frequently Asked Questions

What age groups do you assess for autism?

Our psychology team assesses children, adolescents, and adults. The assessment approach and tools used are adapted to suit the person's age, communication style, and presenting concerns.

How many appointments does the assessment involve?

Most assessments involve an initial intake session plus one or two further sessions for structured observation and any additional questionnaires, followed by a feedback session once the report is complete.

Will I receive a written report?

Yes. Every assessment concludes with a comprehensive written report covering assessment findings, diagnostic outcome (where applicable), and clear recommendations for next steps and support.

Can this assessment support an NDIS application?

A formal diagnostic report from a qualified psychologist can support an NDIS access request or plan review. We can talk you through how the report fits into the broader application process.
