A journey to understanding how your mind works

Autism, ADHD, and cognitive assessments for children and adults. Every assessment concludes with a detailed report and a feedback session, so you leave understanding what we found and what to do next.

What I assess

AutismChildren & adults

For people whose social communication, sensory experience, or development follows a different pattern. The assessment draws on a detailed developmental interview, structured observation using established clinical frameworks and standardised questionnaires from the people who know you best.

The report describes your (or your child's) profile respectfully and specifically — strengths as well as support needs — with tailored recommendations for home, school, or work, and for funding pathways such as the NDIS.

ADHDChildren & adults

A comprehensive picture of attention, impulsivity, and executive functioning, combining clinical interview, computerised testing, and evidence-based screening tools, with informant reports to capture how things look across settings.

Where results support a diagnosis, the report is written to be useful to GPs and psychiatrists considering treatment options, and includes practical strategies you can start on straight away.

CognitiveChildren & adults

A standardised cognitive testing (IQ) provides a clear profile of cognitive strengths and learning needs — commonly used for educational planning, applications for learning support or extension programmes, and access to disability or support services.

Results are always interpreted in context — carefully, and only as far as the data support.

ADHD coachingFollowing assessment

Common questions

Planning your assessment

Current availability. The assessment process can begin within 4 weeks of your enquiry. Spots are limited — early enquiry is encouraged.

How long does an assessment take?
Most assessments are completed within approximately four weeks. The process usually begins with an intake interview, followed by one or two assessment appointments and a feedback appointment. Timeframes can vary depending on the type and complexity of the assessment.
Do I need a referral?
You don't need a referral - you may contact our practice directly to arrange an assessment. Where appropriate, a referral from your GP, paediatrician, or psychiatrist can provide helpful clinical information and support coordinated care.
Can assessments be completed by telehealth?
Some components may be completed by telehealth, while others require in-person attendance in Port Macquarie. The most appropriate format will be discussed during the initial consultation.
What will I receive following the assessment?
You will receive a comprehensive written report outlining the assessment findings, any applicable diagnostic conclusions, and recommendations tailored to your circumstances. A feedback appointment is also included to explain the results and answer your questions.
Can the report support NDIS, educational, or workplace applications?
Where relevant, the report can provide clinical evidence to support NDIS access requests and educational or workplace adjustments. Decisions regarding eligibility, funding, and support remain with the relevant organisation.
