Onpsych provide all types of assessments for any age. Each assessment is individualised to suit the individual's needs and enable informed decision-making, ensuring the best outcomes.

We specialise in psychological assessments, bringing decades of experience.Assessments and testing can be used for a range of purposes, including diagnosis and treatment, and are often used to inform intervention practices.

Our reports are generally used by medical professionals (i.e., GPs, psychiatrists, paediatricians), and other Allied Health professionals such as Occupational Therapists and Speech Therapists to inform their treatment. Our reports and treatment plans are regarded by other professionals as exceptionally comprehensive.

Our assessments are as comprehensive as possible, involving significant others where possible (i.e., including parents,teachers, partners and any other professional/s involved).

Most assessments fall under the following categories:


Diagnostic assessment reports are used for NDIS applications as well as ongoing funding. The NDIS is a complex system and we know how to get the best outcome for the client.


Functional behavioural assessments identify where, when and the likely reasons why behaviour/s issues occur (note: in education these is referred toas a ‘function’ of behaviour).

These assessments inform Behaviour Support and can be assist in Education/ Behaviour Plans. The plans include strategies to assist with behaviours of concern.


We are skilled in selecting the best tests for assessing and treating children, adolescents and adults.

Psychometric Assessments are used to diagnose learning disabilities or difficulties (e.g., Dyslexia), identify strengths weaknesses and make evidence-based recommendations to improve learning outcomes.

Psychometric assessments are also used to screen for other clinical issues including Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD) 1 , with further assessment and/or testing required for a diagnosis.

Psychologists use a range of tools for assessment including standardisedtests, direct observation, and the gathering of background information.

IQ/Cognitive Testing: This testing measures a student’s thinking and reasoning abilities. Areas of investigation include verbal comprehension, visual-spatial reasoning, fluid reasoning, working memory and processing speed. This testing will provide a snapshot of their intellectual ability across these domains.

Achievement Testing: This testing measures a student’s achievement in reading, writing, spelling and maths. These scores are compared to same- aged students to determine if they are performing at, behind or ahead of the expected level.
