What is a functional capacity assessment (FCA)?

Last reviewed 1 July 2026 · 6 min read · By Sarah M., Support Coordinator
In short

A functional capacity assessment is a structured evaluation — usually by an occupational therapist — of how your disability affects everyday functioning across areas like mobility, self-care, communication and community participation. The written report becomes evidence that informs an NDIS access request, plan review, or a request for supports like SIL or SDA.

What an FCA measures

An FCA looks at function, not diagnosis — what you can and can’t do day to day, and how much support you need. Assessors use standardised tools and observation to build an objective picture.

It typically covers several domains so the NDIA can see the whole impact of disability on daily life.

Self-care & mobility

Showering, dressing, moving safely around home and community.

Communication

Understanding and being understood in everyday situations.

Social & community

Participating, managing relationships and daily routines.

Who carries out an FCA and when you need one

FCAs are usually completed by occupational therapists, sometimes alongside physiotherapists, speech pathologists or psychologists for specific domains.

People commonly seek one when making an access request, preparing for a plan review, or building evidence for higher-cost supports such as Supported Independent Living or assistive technology.

What to expect and how the report is used

An assessment may involve an interview, hands-on tasks and sometimes a home visit, then a written report describing your capacity and recommended supports.

The report is evidence that informs the NDIA’s decision — it doesn’t decide the outcome itself, but a clear, current FCA helps the planner understand what reasonable and necessary support looks like for you.

Our support coordinators can help you understand assessments and organise the right evidence for your plan.

Common questions

Questions, answered.

Who can do a functional capacity assessment? +
Most often an occupational therapist; other allied-health professionals may assess specific areas like communication or mobility.
Does the NDIS pay for an FCA? +
Assessment costs can often be funded from Capacity Building (Improved Daily Living) where reasonable and necessary; check your plan or ask your support coordinator.
Is an FCA the same as an OT assessment? +
An FCA is a type of OT assessment focused specifically on everyday functional capacity and the supports it justifies.
How long does an FCA take? +
It varies — from a single session to a few hours across visits, plus time for the assessor to write the report.
Do I need an FCA to apply for the NDIS? +
Not always, but functional evidence strengthens an access request. The NDIA looks at how disability affects daily life, which an FCA documents well.
