Getting a Diagnosis

Aspect Assessments provide both adult autism diagnosis and children autism diagnosis assessments for individuals across their lifespan. Our comprehensive assessment can identify developmental difficulties and determine what strategies and supports will assist a person to achieve their goals and reach their full potential.

Please note: Aspect’s waitlist for an autism assessment is currently a minimum of 12 months. At this stage, we are taking names for the waitlist and notifying people if an earlier appointment becomes available.

What to expect when getting an assessment

Aspect has created animated social stories to help you learn about the assessment process and to know what to expect. We have videos for both face-to-face and Telehealth assessments for children and adults.

These autism assessments – also known as diagnostic assessments – can determine whether someone has autism. They’re also useful for individuals who have previously been diagnosed with autism but are now wanting an updated assessment and additional information. These are also known as review assessments and are useful to help individuals with funding applications or support planning.

Autism assessments are able to be offered face-to-face in one of our clinics (Sydney and Coffs Harbour) or via telehealth.

Cognitive assessments help to determine an individual’s learning capability. They identify cognitive strengths and weaknesses, and can assist with the development of individualised support and learning plans.

Cognitive assessments are conducted face-to-face in one of our clinics (Sydney and Coffs Harbour), and are not available via telehealth.

Assessment FAQs

Diagnosing autism can be a challenge because there is no single medical test – like a blood test – to assist with making a diagnosis. That’s why we prefer the phrase ‘assessment’, which more accurately describes the diagnosis process.

During assessments experts review an individual’s developmental history and behaviours in order to make a diagnosis over time.

ASD is the acronym for autism spectrum disorder. This umbrella term was created in 2013 by the American Psychiatric Association and covers a wider range of disorders than just autism. For clarity, at Aspect we use the term autism rather than ASD, and ‘autism assessments’ rather than ‘ASD assessments’. We also use the term ‘autistic person’ to recognise, affirm and validate that individual’s unique identity, value and worth.
