An Autism assessment is a comprehensive evaluation involving multiple sessions, detailed observations, and various standardised tools. Here’s a breakdown of what the process entails, how to prepare, and what the results mean.

What Does an Autism Assessment Involve?

The assessment typically includes several sessions, each lasting around 50-60 minutes. These sessions involve a combination of questions, standardised tests, and behavioural observations designed to evaluate the presenting concerns and traits of the child.

• Parent Interview: One session often focuses on a detailed interview with the child’s parent(s) or caregiver(s), lasting between 1-2 hours. This discussion explores the child's developmental history and any behavioral concerns.
• Observations: Depending on the assessment, a psychologist might observe the child in familiar environments, such as home or school, to gather a more comprehensive picture of their social interactions and behaviors.
• Cognitive Testing: This component may include assessments of the child's intellectual functioning to identify strengths and areas where support may be needed. Commonly referred to as cognitive testing, this helps in formulating effective learning and support strategies.

Commonly Used Assessment Tools

Several tools are commonly used to assess autism. Each professional may vary slightly in approach, but here are some standard tools often included:

• Vineland Adaptive Behavior Scale: Assesses adaptive behaviors, including daily living skills and communication.
• DSM-5 Criteria: Utilizes the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) for a clinical diagnosis of Autism Spectrum Disorder.
• Autism Diagnostic Interview – Revised (ADI-R): A structured interview with caregivers to explore developmental history.
• Childhood Autism Rating Scale (CARS-2): A tool used to evaluate autism severity.
• Social Responsiveness Scale (SRS): Measures social impairments characteristic of autism.

Preparing for the Assessment

To maximise the assessment’s effectiveness, preparation is essential. Here are some steps to consider:

• Gather Previous Documentation: Bring any relevant reports, past assessments, and school reports that may assist the assessment team.
• Observe Your Child: Take notes on specific behaviours, communication patterns, and instances that align with common autism traits (e.g., how often they point, use certain words, etc.).
• Be Realistic: While it may be challenging, it’s crucial to provide a clear, honest picture of your child’s behaviours, without overestimating or downplaying them.

Understanding the Results

Once the assessment is complete, a verbal feedback session is held where the psychologist discusses the findings, including potential diagnoses and recommendations for treatment or further referrals.

• Comprehensive Report: You’ll receive a detailed written report covering the assessment results, any diagnosis, and recommendations for ongoing support or interventions.
• Confidentiality: Assessment details remain private and are only shared with others upon receiving prior consent.

Evidence for NDIS Access

If seeking NDIS funding, specific levels of autism (Levels 1 and 2) have automatic acceptance. For Level 1, additional evidence is typically required. Common forms of acceptable evidence include:

• DSM-5 Assessment Results
• Vineland Adaptive Behaviour Scale (Vineland-II)
• World Health Organisation Disability Assessment Schedule (WHODAS) 2.0 (for those 17+)
• PEDI-CAT (for children under 16)

Only one of these documents is generally necessary for NDIS applications.

By understanding each stage of the autism assessment, preparing thoroughly, and utilizing available resources, you can ensure a supportive and thorough evaluation for your child or loved one.
