What Happens in an Autism Assessment
Deciding to seek an autism assessment is a significant step, and most parents arrive with a mix of hope, worry, and a very long list of questions. An assessment is not a test your child can fail. It is a careful, structured way of understanding how your child thinks, communicates, and experiences the world, so that the people around them can support them better. This guide walks you through the process, from referral through to report.
Around 1 in 70 Australians are autistic (Australian Institute of Health and Welfare), and identification is becoming more accurate, particularly for girls and gender-diverse young people.
Assessment in Australia follows the National Guideline for the Assessment and Diagnosis of Autism, developed by Autism CRC and approved by the NHMRC.
A good assessment produces far more than a yes or a no. It produces a picture of your child’s strengths, their needs, and the supports that will genuinely help.
Before You Begin: The Referral
You do not always need a referral to book an assessment privately, but it helps to have your GP or paediatrician involved from the start.
Your GP can talk through your concerns, rule out other explanations such as hearing difficulties, and refer on where needed.
Your paediatrician, if your child has one, can refer for assessment and coordinate the medical side of things.
School observations are gold. Teachers and wellbeing staff see your child in the setting where social and sensory demands are highest.
Before you book, it is worth asking who will be involved, how long the process takes, and what the final report will include.
What the Assessment Involves
A comprehensive assessment gathers information from several sources, because no single appointment or questionnaire can capture a whole child. The process usually includes the following.
Developmental history
A long, detailed conversation with you about your child’s early development, milestones, communication, play, sensory preferences, and relationships.
This interview is often the richest single source of information in the entire assessment, so your memories genuinely matter.
Direct assessment with your child
Standardised observation, often using the ADOS-2 or MIGDAS-2, which are structured but deliberately play-based and conversational.
Cognitive assessment, such as the WISC-V, where it adds clarity about learning, thinking, and where support is needed.
Sensory, adaptive, and behavioural measures that describe everyday functioning rather than diagnosis alone.
Information from the people who know your child
Questionnaires completed by you and, with your consent, by your child’s teacher.
Reports from any other professionals involved, such as speech pathology, occupational therapy, or paediatrics.
Assessment sessions are designed to be manageable. We break them into shorter blocks, build in breaks, and let your child bring whatever helps them feel comfortable. If your child is having a hard day, we adjust, because we want to see them at their best rather than at their most stretched.
How Long It Takes
Most assessments involve two to four appointments, spread across a few weeks.
Each appointment usually runs between one and two hours, depending on your child’s age and stamina.
Written reports take a few weeks to complete after the final session, because they are written carefully rather than quickly.
You will be given a clear timeframe at the start, and we will tell you promptly if anything changes.
The Feedback Session
Once all the information is gathered, we bring it together and sit down with you to talk it through. This is one of the most important parts of the whole process, and it is never rushed.
We explain what we found, in plain language, and what it means for your child day to day.
We talk about strengths as well as challenges, because both belong in an accurate picture.
We answer your questions, including the hard ones and the ones you may feel silly asking.
We discuss how and when to talk with your child about the outcome, and we can help you plan that conversation.
The Report and What Comes Next
At Newport Counselling & Psychology Service our reports are written to be useful for families, schools, the NDIS, and other clinicians, not to sit in a drawer. Each one includes a clear formulation and practical, specific recommendations.
For school, the report supports classroom adjustments, NCCD evidence, and conversations with wellbeing staff.
For the NDIS, a diagnostic report with functional information supports an access request, though a diagnosis on its own does not guarantee funding.
For therapy, the recommendations point to what is likely to help, whether that is psychology, occupational therapy, speech pathology, or parent support.
For your family, the report offers language and understanding that make daily life make a great deal more sense.
Whatever the outcome, your child is the same child they were the day before the assessment. What changes is the understanding around them, and that is usually what makes life easier. Take your time with the results, and know that we are here for the questions that surface weeks later, not just on the day.
If you haven't been to that first session yet, you might also want to read our guide on what to expect from your child's first psychology appointment.
