Intellectual Disability Assessment

Diagnostic "DSM-5" ID Assessment for children, adolescents, and adults


Diagnostic assessment for private clients, or self-managed or plan-managed NDIS participants. Determine if an individual meets DSM-5 criteria for an intellectual disability (ID) and accompanying severity level. This assessment is recommended when an intellectual impairment is suspected or requires review or severity level confirmation.

NDIS Support
& Review

Obtain NDIS funding and NDIS review. Evidence of meeting criteria for an intellectual disability and accompanying severity level can be used to apply for a range of supports, including NDIS.

Support Recommendations

Be provided with a comprehensive overview of an individuals cognitive profile, strengths, and limitations. Receive tailored and informed support recommendations to assist with the right care and management.

What is an intellectual Disability?

An intellectual Disability is a lifelong condition, causing an individual to have significant difficulties in both intellectual functioning (reasoning, learning, and problem-solving) and adaptive behaviour (social and practical skills necessary for day to day functioning). The onset of these difficulties is evident before the individual is 18 years old. 

What does Intellectual Disability Assessment involve?

Intellectual Ability (IQ) And Functioning Assessment (WAIS-IV)

This assessment is used to assess an individual’s level of general intellectual functioning. 

Adaptive Behaviour Assessment System 3rd Edition (ABAS-3)

These measures assess an individual’s adaptive behaviour. This measures every day functioning across practical, social, and conceptual domains. 

Additional Tools

Ratings scales to measure mental health also provide useful information. Depending on the referral question and case complexity, additional screening tools may be recommended.

How many appointments are required?

Session One

Adult Clients: Intake session with individual and parent/guardian/support worker if required (1 hour)
