Autism Spectrum Disorder Assessments

Evidence-Based Assessments Across the Lifespan

I conduct Autism Spectrum Disorder (ASD) assessments in Sydney to provide clarity, understanding and practical direction for children, adolescents and adults who may be experiencing social, behavioural or sensory differences.

An assessment helps determine whether someone meets diagnostic criteria for ASD and, importantly, identifies their unique strengths, challenges and support needs. Many individuals seek assessment to better understand lifelong differences, to access appropriate school or workplace adjustments, or to obtain evidence for NDIS or other services.

A comprehensive assessment can:

  • Clarify whether behaviours are consistent with autism

  • Differentiate ASD from ADHD, anxiety, trauma or learning difficulties

  • Identify support needs across home, school or work environments

  • Provide documentation for funding, accommodations or services

  • Offer individuals and families greater self-understanding and direction

The goal of assessment is not simply to provide a diagnosis, but to offer meaningful insight and clear recommendations that support wellbeing and long-term functioning.

Who is this assessment for?

Children & Adolescents

An Autism Spectrum Disorder assessment may be helpful if your child:

  • Has difficulty with social communication or understanding social cues

  • Prefers routines and finds change distressing

  • Displays intense or focused interests

  • Experiences sensory sensitivities

  • Finds peer relationships challenging

  • Has a history of developmental differences

We carefully consider developmental history and presentation across settings.

Adults

An Adult Autism Spectrum Disorder assessment may be appropriate if you:

  • Have longstanding social communication differences

  • Experience sensory sensitivities

  • Prefer predictability and structure

  • Feel socially exhausted or misunderstood

  • Have previously been diagnosed with anxiety or depression but feel there may be more underlying

Many adults seek assessment later in life for clarity, self-understanding, or workplace support.

What does the Autism Spectrum Disorder Assessment involve?

Each assessment is tailored to the individual, but typically includes:

1) Initial Clinical Interview

A detailed developmental and psychosocial history, including:

  • Early childhood development

  • Social and communication patterns

  • Sensory experiences

  • Educational or occupational history

  • Emotional wellbeing

  • Strengths and interests

For children, caregiver interviews are an essential part of the process.

2) Standardised Diagnostic Tools

I utilise structured, evidence-based assessment measures, which may include:

  • ADOS-2 (Autism Diagnostic Observation Schedule)

  • ADI-R (Autism Diagnostic Interview – Revised)

  • Autism-specific questionnaires

  • Adaptive functioning testing

  • Cognitive testing (if indicated)

  • Screening for co-occurring conditions such as ADHD or anxiety

The specific tools used depend on age, presentation and referral question.

3) Clinical Formulation

Assessment findings are integrated to determine:

  • Whether DSM-5 diagnostic criteria for Autism Spectrum Disorder are met

  • The individual’s support needs

  • Co-occurring conditions

  • Strengths profile

I take care to consider differential diagnoses and overlapping presentations.

4) Feedback Session

A dedicated session to:

  • Explain findings clearly and respectfully

  • Discuss strengths and differences

  • Explore practical supports

  • Answer questions

I aim to provide clarity without pathologising neurodiversity.

5) Comprehensive Written Report

You will receive a detailed report including:

  • Background history

  • Assessment findings

  • Diagnostic conclusions (if applicable)

  • Strengths and interests profile

  • Support recommendations for home, school or workplace

Reports are written in clear, professional language and are suitable for:

  • GPs

  • Paediatricians

  • Psychiatrists

  • Schools

  • Workplace accommodations

  • Funding or support applications (where applicable)

Why a Comprehensive Autism Spectrum Disorder Assessment Matters

A thorough assessment can:

  • Provide clarity after years of uncertainty

  • Reduce confusion or self-blame

  • Inform appropriate supports

  • Guide educational or workplace adjustments

  • Support access to services where relevant

  • Strengthen self-understanding and identity

Diagnosis is not simply a label — it is a framework for understanding.

My approach

My Autism Spectrum Disorder assessments are:

  • Structured and evidence-based

  • Developmentally informed

  • Strengths-focused

  • Thoughtful and individualised

  • Delivered with professionalism and care

I recognise that each person’s neurodevelopmental profile is unique.
