If you're navigating the NDIS, you've likely come across the term Functional Capacity Assessment (FCA), usually right around the time you're preparing for a new plan, a plan review, or after the NDIS has asked for more information. It can feel like just another piece of paperwork, but it can play an important role in shaping the support you receive.

In this post, we'll unpack what an FCA actually involves, and why the NDIS might ask for one!

What Is a Functional Capacity Assessment

(FCA)?

A Functional Capacity Assessment looks at how you go about daily life, at home, at work, and in your community. It's designed to highlight what you do well and where you might need a bit more support, across areas like mobility, self-care, communication, social interaction, learning, self-management, and decision-making.

Rather than just listing difficulties, a good FCA looks at the full picture, your strengths as well as your challenges, to build an accurate, genuinely useful understanding of your everyday life (just written in the more formal language the NDIS expects).

Why Does the NDIS Ask for a Functional Capacity Assessment?

The NDIA (the organisation that runs the NDIS) uses your FCA as evidence to work out what supports are right for you. This might include things like assistive technology, specific therapies, or modifications to your home. Essentially, it gives the NDIA objective, professional evidence to guide their funding decisions, including, under more recent NDIS changes, how your funding is structured across your 12-month plan period.

You'll often be asked for an FCA when:

You're putting together a new NDIS plan
You're going through a plan review
Your needs have changed significantly, for example, if your disability-related support needs have increased or become more complex
The NDIS has requested more information to assess your eligibility or ongoing supports

Think of it as a big picture report, one that captures what your everyday life actually looks like, what's genuinely hard to manage independently, and what kind of support would help you work toward your goals.

Who Completes a Functional Capacity Assessment?

FCAs are most commonly completed by Occupational Therapists. OTs are specifically trained to understand how physical, emotional, and cognitive factors all interact to shape a person's ability to function in everyday life, which is exactly what an FCA is trying to capture. In some cases, another allied health professional or medical specialist might complete the assessment instead, if they're better suited to your particular needs.

A thorough FCA usually isn't a single conversation or checklist, it often involves a mix of discussion and more formal assessment tools.

More Than Just an Assessment, It's Advocacy

One of the most important parts of an OT's role in this process is advocating for you. Your FCA report doesn't just list findings, it connects those findings to your goals, and explains how each recommended support aligns with NDIS criteria for what's considered "reasonable and necessary." This report is what you'll bring to your planning meeting or review as evidence, and the NDIA will ultimately decide whether each recommended support is approved.

A well-written, thoughtful FCA report can make a real difference here. It's the difference between the NDIA simply seeing a list of difficulties, and genuinely understanding the level and type of support you need to live safely, work toward your goals, and lead a fulfilling life.
