Intellectual Disability Assessment
An intellectual disability assessment explains why learning, memory, or everyday tasks work differently for you or your child, and what actually helps
Under the NDIS, intellectual disability assessed as moderate, severe, or profound against current DSM criteria appears on List A, which covers the conditions considered likely to meet the disability requirements. A milder presentation can still be considered, though it needs evidence of permanent functional impact.
Scope provides strengths-based intellectual disability assessment for people of all abilities, including those who are blind or deaf and those with limited speech or motor control. We hold a library of assessment tools built for exactly those situations. A psychological assessment for intellectual disability looks at cognitive ability alongside adaptive functioning, then turns what it finds into practical changes at home, at school, or at work. Schools and the NDIS are the two most common reasons people ask for one.

What is intellectual disability?
Intellectual disability is a lifelong difference in how the brain processes information. It shows up in two places: reasoning ability and the everyday skills a person uses to look after themselves, communicate, and get through a day. The DSM-5-TR, which calls it intellectual developmental disorder, requires differences in both, with onset before adulthood. An IQ score on its own is not a diagnosis.
That second measure is where the useful information sits. Two people with identical IQ scores can live completely differently, which is why assessment for intellectual disability also looks at adaptive functioning: managing money, getting around, cooking, staying safe, reading a social situation, holding down work or school.
That first measure produces a cognitive profile, meaning the specific peaks and dips across verbal comprehension, reasoning, and memory. That's the part families and adults actually use, because it points to what helps rather than only naming what's hard. Support needs also shift with the environment someone is in, and they can change over a lifetime.

Assessment at any age
We assess from early childhood through to later life. The diagnostic criteria don't shift with age, so an intellectual disability assessment for adults is held to the same standard as one for a nine-year-old, with the pacing and the choice of tools adapting instead.
This matters most at the transition points: a young person moving from paediatric to adult services, or a lifelong pattern that gets harder to manage after a change in work, health, or living situation.
