Functional Capacity Assessments for NDIS Participants with Intellectual Disability

Participants with intellectual disability present a uniquely intricate functional profile. Adaptive functioning impairment — across conceptual, social and practical domains — is often masked by familiar routines, family scaffolding and decades of learned coping strategies. A generic FCA, conducted as a single point-in-time interview, regularly under-documents the true supervision intensity required when those familiar scaffolds are removed.

Our intellectual disability FCA is built around capturing the *real* level of support required across novel situations, decision-making under risk, and self-management of health, finances and safety — not just within the comfort of an established routine.

Adolescents (15+) and adults with diagnosed intellectual disability — mild, moderate, severe or profound — who require evidence for an NDIS plan reassessment, access request, SIL/ILO application, change of circumstances or a transition to adult services. Participants with co-occurring intellectual disability and autism, Down syndrome, foetal alcohol spectrum disorder (FASD), Fragile X, Williams syndrome, Prader-Willi syndrome or unspecified developmental disability are routinely assessed.

We also support participants with borderline intellectual functioning where significant adaptive functioning impairment is present despite IQ scores above the formal threshold for intellectual disability.

Step 1 — Secure intake. Submit our online referral form with NDIS plan, prior cognitive assessments, behaviour support plans and any current allied health reports. We confirm referral acceptance within one business day.

Step 2 — Document review. Our Occupational Therapist reviews diagnostic reports, school/post-school documentation, support worker observations and any prior FCAs to build a baseline understanding of adaptive function before interview.

Step 3 — Clinical interview. Telehealth assessment delivered across multiple shorter sessions (30–60 minutes each) to accommodate fatigue, working memory and communication style. Family members, Support Coordinators and support workers participate where relevant.

Step 4 — Collateral observation. We seek structured observation from support workers, parents and educators who see the participant across multiple environments — including unfamiliar settings where scaffolds are absent.

Step 5 — Report drafting. Comprehensive 30–60 page FCA report mapped against the eight NDIS functional domains, quantifying supervision intensity, safeguarding requirements and recommended support hours.

Step 6 — Report issue. Delivered within 5 business days of the final interview, with a 14-day clarification window at no extra cost.

Capacity building supports — daily living skill development, social skills, money handling, public transport and safety training. These supports are typically recommended for long-term, repeated delivery because skill acquisition in intellectual disability cohorts is slower and benefits from sustained repetition.

Core supports — 1:1 community access, in-home support during high-risk activities (cooking, medication, bathing), and supervision during unstructured time. The level of support recommended is justified against the participant's adaptive functioning profile and safeguarding risk profile.

Allied health — Occupational Therapy, Speech Pathology, Psychology and Positive Behaviour Support hours where indicated by the assessment.

Home and living evidence — for participants approaching adulthood or transitioning out of the family home, our FCA provides the foundation evidence for ILO Stage 1, SIL or SDA applications. See our SIL assessment and Home & Living assessment pages for more detail.

Many participants with intellectual disability communicate in ways that benefit from accommodation — slower speech, plain language, visual supports, or augmentative and alternative communication (AAC). Our clinicians use these strategies as standard, allow extra processing time, and never rely on yes/no questioning for substantive information.

Consent is gathered in a supported decision-making framework — with family, guardian or nominee participation where appropriate. Cultural safety considerations (interpreter, Aboriginal Liaison Officer, religious or community supports) are arranged at no additional cost.
