What a Functional Capacity Assessment Covers
If your NDIS planner, GP, or support coordinator has mentioned a functional capacity assessment, you may be wondering what it actually involves and why it matters. An FCA can feel like a lot of paperwork and appointments, but it is one of the most useful documents you can have when it comes to making sure your NDIS plan reflects your real needs. This article explains what an FCA is, what it looks at, how the assessment works, and how the NDIA uses the report.
TLDR
- A functional capacity assessment (FCA) is an official evaluation of how your disability affects your ability to manage daily life at home, at work, and in the community.
- The NDIS evaluates functional capacity across six domains: communication, learning, mobility, self-care, self-management, and social interaction.
- FCAs are most commonly completed by occupational therapists, who are trained to assess how health conditions affect participation across all areas of daily life.
- The assessment involves a clinical interview, standardised tools, and real-world observation, typically taking two to four hours.
- The written FCA report gives the NDIA structured evidence to determine what supports are reasonable and necessary for your plan.
- An FCA is not mandatory for NDIS eligibility, but it provides strong evidence for access requests, plan reviews, and new support applications.
- A report written specifically to align with NDIS guidelines is more effective than a general clinical summary.
What Is a Functional Capacity Assessment?
A functional capacity assessment is an official assessment that looks at how your disability or health condition affects your ability to manage daily tasks at home, at work, and in the community. It is most commonly completed by an occupational therapist, who is specifically trained to assess how health conditions affect participation in everyday life across all life areas.
The result is a written report used by the NDIA to understand your support needs and guide the decisions made in your plan. While an FCA is not mandatory for NDIS access, it provides structured, evidence-based information that is difficult to convey through a GP letter alone.

The Six NDIS Functional Domains
The NDIS defines functional capacity across six domains. Your FCA will assess how your disability affects you in each of these areas.
| Domain | What it covers |
| Communication | Your ability to understand and be understood through speech, writing, or other methods |
| Learning | Your ability to take in new information, develop skills, and apply knowledge to daily situations |
| Mobility | Your ability to move around independently, use mobility aids, and manage transfers safely |
| Self-care | Dressing, bathing, grooming, toileting, and managing personal hygiene |
| Self-management | Managing daily routines, finances, medication, decisions, and organising your life |
| Social interaction | Engaging with others, maintaining relationships, and participating in community activities |
The FCA does not simply note whether you can perform a task. It documents the impact of your disability on how you perform it, how long it takes, whether you need prompting or assistance, and whether the effort involved affects your safety or wellbeing.
What the Assessment Process Involves
The assessment follows a structured process. Knowing what to expect at each stage helps make the experience more manageable.
Clinical interview and history taking
The OT begins with a detailed clinical interview to understand your history, diagnosis, daily routines, current supports, and goals. This conversation is the foundation of the assessment. It helps the OT build a picture of your situation before introducing any tools or observational tasks. You are encouraged to describe a typical day, the things you find difficult, and what you would like to be able to do with better support in place.
Standardised tools and real-world observation
Following the interview, the OT uses validated, standardised assessment tools to measure specific areas of function. Where practical, they also observe you completing real tasks in your home or community environment. Observing tasks in context, rather than relying on self-report alone, produces a much more accurate picture of everyday capacity and the support that would make a difference. The full assessment typically takes two to four hours of direct contact time. If you are ready to get started, you can submit a referral online.
What the FCA Report Contains
The written FCA report is the key deliverable. A well-written report includes:
- A summary of your diagnosis, medical history, and current situation
- Findings across each of the six functional domains
- Results from standardised assessment tools, with scores interpreted in plain language
- Observations from real-task assessment, where conducted
- A clear summary of your current support needs
- Specific recommendations for NDIS supports, with the functional reasoning behind each
Recommendations may cover support workers for personal care or domestic tasks, community access supports, therapy, assistive technology, and modifications to the home or vehicle. Where equipment and home environment assessments are also recommended, the FCA may flag these for a follow-up assessment. Reports prepared for NDIS purposes are written to align with NDIA terminology and guidelines, which makes them more effective as evidence than a general clinical letter.
Who Needs an FCA Under the NDIS?
An FCA is commonly needed in the following situations:
- You are applying for NDIS access and your diagnosis alone does not clearly demonstrate the functional impact of your disability
- You are approaching a plan review and your current funding does not reflect your real support needs
- You are requesting a new type of support, such as assistive technology, home modifications, a support worker, or specialised therapy
- Your condition has changed or progressed since your last plan
- Your support coordinator or planner has requested stronger functional evidence
In many cases, support coordinators, GPs, or allied health teams will initiate the referral on your behalf. It is worth noting that having a diagnosis is not the same as having functional evidence. The NDIA needs to understand how the diagnosis affects your daily life, and that is exactly what the FCA provides. If you are also exploring driving as a goal, an OT driving assessment is a separate process that can run alongside or following an FCA.
How the NDIS Uses Your FCA
The NDIA uses your FCA report to determine what supports are reasonable and necessary to include in your NDIS plan. A strong, clearly evidenced report gives the agency a structured basis for making those decisions and reduces the likelihood of supports being declined, underfunded, or poorly matched to your needs.
The report does not guarantee any particular outcome. The NDIA considers the FCA alongside other information in your plan and applies its own guidelines. However, a report written by a qualified occupational therapist, using validated tools, real-world observations, and NDIS-aligned language, is a significantly stronger piece of evidence than an unstructured letter or self-report alone. It is the clearest way to translate what you live with every day into the language the system understands.
