We offer diagnostic assessments for autism spectrum disorder for both children and adults.

What does an autism assessment for an adult involve? 

An autism assessment with an adult generally takes place over an 8-10 week period, and includes:

Pre-diagnostic Assessment Interview

50 minutes

If you are referring yourself for an autism assessment (ie: you don't have a GP or psychiatrist referral), a pre-diagnostic assessment interview is recommended in order to discuss:

  • Reasons for and potential benefits of pursuing an assessment

  • What will be included in the assessment process if deemed beneficial

  • Completion of screening questionnaires


If you wish to proceed with the assessment, two assessment sessions will be scheduled.

Assessment Session #1

3 hours


Clinical interview with the adult who may have ASD to review relevant developmental, psychosocial and medical history, address the DSMV criteria for an autism spectrum disorder, and identify personal strengths and talents. Formal testing of cognitive skills will be completed if required or requested.

Assessment Session #2

3 hours

Clinical interview with a spouse, partner, parent or another family member for collateral information. Ideally, this is someone who knows the person well and can provide information about their developmental history and current functioning. Formal testing of adaptive skills may also be conducted if required (e.g., for access to funding or services).

Feedback Session

50 minutes

Comprehensive feedback regarding the assessment results, including clarification of whether the diagnostic criteria for Autism Spectrum Disorder have been met and suggestions regarding support and resources that may be helpful.


How much does it cost? 

The full fee for an Adult Autism Assessment is $2300 which includes a detailed diagnostic report.


Payment for autism assessments can be made in instalments by prior agreement with our reception staff. However, full payment of the assessment and any report fees must be made before a detailed diagnostic assessment report is compiled.


Do Medicare rebates apply for adult autism assessments? 

No. Medicare rebates do not apply for adult autism assessment sessions but you may be able to claim a rebate from your private health insurer for assessment sessions. Please contact your insurer to clarify your eligibility.
