Where most people start

Most people first hear this term
when they are already under pressure

A parent may be trying to explain why their child needs more help at school than the current supports provide — and has been told an FCA would help make the case. An adult may be preparing for an NDIS plan review and trying to show why their current funding no longer matches what they actually need. A carer may be exhausted from providing invisible support every day and is only beginning to realise that the situation cannot continue as it is.

At that point, being told you need a "Functional Capacity Assessment" can feel like one more complicated step in an already complicated process. The term sounds formal. The process sounds uncertain. And the cost can feel like another barrier.

This article tries to explain clearly what a Functional Capacity Assessment actually is, what it looks at, how it is used in the NDIS context, and what a good one should do. It also explains how Seeds OT approaches the process — including what we do and what we are honest about not being the right fit for.

The key concept

Functional capacity is not about
what a person can do once

Functional capacity is about what a person can do safely, consistently and sustainably — across ordinary life, not just on a good day or in ideal conditions.

This distinction matters more than it might first appear. Many people can do something once, with the right conditions, when they are rested, calm, and have support around them. The question an FCA is really asking is whether they can do it reliably across a normal week — without undue fatigue, distress, risk, or another person quietly filling the gaps behind the scenes.

Safe, consistent and sustainable — what this means in practice
Can do — once
In ideal conditions, on a good day
Showers independently when prompted — but does not maintain hygiene without daily reminders
Cooks a meal when supported — but cannot plan, shop, prepare and clean up safely across a week
Follows instructions in a calm one-to-one setting — but cannot manage classroom transitions or playground demands
Travels once with a support person — but cannot navigate independently or manage unexpected changes
Can do — consistently
Across an ordinary week, not just best days
Manages personal care most days without prompting — though fatigue days require support
Prepares simple meals reliably — but complex cooking or planning is not manageable
Participates in classroom learning with adjustments — though transitions and unstructured time remain difficult
Uses familiar public transport on known routes — but new routes or disruptions cause significant difficulty
Can do — sustainably
Without unreasonable cost, risk or carer burden
Manages independently without another person filling gaps behind the scenes every day
Completes tasks without significant fatigue, shutdown, pain or emotional dysregulation as a result
Participates in daily life without a carer carrying a hidden support load that is not formally recognised
Maintains routines safely — without risk to self, others, or the sustainability of informal support
A good FCA asks all three questions — not just whether something is possible, but whether it is safe, consistent and sustainable in real everyday life.

A person may appear capable because a parent, partner, sibling or carer is quietly doing many tasks behind the scenes. They may present well in an appointment but be unable to manage appointments, paperwork, transport, budgeting or daily routines in the rest of their life. An FCA is trying to understand real-life function — not just isolated ability at its best.

A common misconception

Diagnosis is important —
but it does not show how someone functions

Diagnoses matter. They explain underlying conditions. They open doors to services. They can validate what families have known for years. But a diagnosis alone does not show how a person manages day to day — and two people with exactly the same diagnosis may have very different support needs.

One may manage many daily tasks with minimal support. Another may need high levels of prompting, supervision, physical assistance, emotional regulation support, or help to access the community safely. The diagnosis is the same. The functional picture is entirely different.

Same diagnosis — very different daily lives
An illustration of why functional evidence matters alongside diagnosis
Same diagnosis
Person A
Manages personal care independently most days
Can prepare simple meals with some planning support
Uses public transport on familiar routes
Attends appointments with reminders from family
Works part-time with adjustments
Same diagnosis
Person B
Requires daily prompting for hygiene and dressing
Cannot safely manage cooking, shopping or meal planning
Cannot use transport independently — relies on carer
Cannot manage appointments, forms or phone calls without support
Cannot maintain employment — significant executive function and regulation difficulties
The diagnosis tells us about the condition. The FCA tells us about what is actually happening in daily life — and what support is reasonably needed.

The FCA helps explain the practical impact of disability: what is hard, why it is hard, what support is currently being provided, what happens when support is not available, what risks arise, and what supports may be reasonable and necessary.

The NDIS context

The NDIS needs more
than a diagnosis

The NDIS often needs functional evidence — information that shows how a person's impairment affects daily life, participation, safety, independence and support needs. A diagnosis names a condition. An FCA explains what that condition means in practice, in this person's life, right now.

A strong Functional Capacity Assessment can support a range of NDIS situations:

When an FCA can help in the NDIS context
→NDIS access requests — providing functional evidence alongside diagnostic information
→Plan reviews — showing that current funding no longer matches real needs
→Change of circumstances — documenting functional decline or changed support arrangements
→Requests for increased support — providing clinical justification for additional hours or services
→Carer burden — making visible the informal support that is not formally recognised or funded
→Identifying risks — showing what happens when support is not in place
→Assistive technology or home modification needs — providing functional evidence for equipment or environmental changes

An FCA does not guarantee NDIS funding. The NDIA makes its own decisions. The role of the FCA is to provide clear, honest, clinically reasoned functional evidence — and to help planners and reviewers understand what daily life is actually like.

The breadth of assessment

What a Functional Capacity Assessment
actually looks at

The domains covered in an FCA depend on the person's age, disability, life situation and the reason for referral. Not every FCA covers every area in the same depth — the assessment should be tailored, not generic. Below is a guide to the kinds of areas commonly considered for children and for teenagers and adults.

Common functional domains — children and adults
Children
Self-care — dressing, hygiene, toileting, grooming
Mealtimes — eating, food management, feeding independence
Sleep — settling, night waking, sleep routines
Play — independent, imaginative, social play
School participation — learning, attention, task completion
Transitions — moving between activities, settings, people
Sensory processing — sensitivity, seeking, tolerance
Emotional regulation — managing big feelings, recovery time
Communication — understanding, expression, social interaction
Safety awareness — risk recognition and management
Community access — outings, public spaces, transport
Parent supervision needs — level and type of support required
Teenagers & Adults
Personal care — hygiene, dressing, grooming, medication
Domestic tasks — cooking, cleaning, laundry, shopping
Transport — driving, public transport, community navigation
Appointments — attending, managing, communication with services
Money management — budgeting, bills, financial decision-making
Executive functioning — planning, organising, initiating, following through
Work or study — participation, capacity, adjustments needed
Social participation — relationships, community, isolation
Emotional regulation — fatigue, pain, stress, shutdown, overwhelm
Mobility — movement, physical capacity, pain
Safety — risk at home, in the community, when support is absent
Informal carer support — who is providing support and whether it is sustainable
Every FCA is tailored to the individual — not every area is assessed in the same depth for every person.
What is often invisible

The hidden role of
informal carers

One of the most important things an FCA can do is make invisible care visible. Parents, partners, adult children, siblings or other family members may be providing daily support that has become so normal inside the family that nobody has stopped to name it — even though the level of support involved is far beyond what would usually be expected of a family member.

This support might include prompting hygiene every morning, managing all appointments and paperwork, supervising safety at all times, preventing or managing meltdowns or risky behaviour, regulating emotional distress, preparing every meal, driving everywhere, completing all forms and communications with services, and carrying the mental load of anticipating every difficulty before it happens.

When a carer has been doing this for years, they often do not realise how much they are providing — or what would happen if they were no longer able to. The FCA should ask those questions.

— Nisha Bal, Seeds OT

A good FCA considers whether informal support is sustainable, whether carers are becoming exhausted, and what might happen if those supports reduced or broke down. For many families, this section of the assessment reflects a reality they have never been asked to articulate before — and it can be one of the most important parts of the report.

How we work

The Seeds OT process —
structured, thorough, telehealth-based

Seeds OT provides Functional Capacity Assessments Australia-wide via telehealth. Our process does not involve in-person observation in different settings — where that kind of observation is clinically necessary, we will say so and suggest a more appropriate provider or model.

Our standard FCA process works like this:

Structured questionnaires — completed before the appointment. The participant, parent, carer, or someone who knows the person well completes detailed forms in their own time. These are not a formality. They are a clinically important part of how we understand the person before we meet.
Document review. Relevant documents can be uploaded before the appointment — NDIS plans, medical letters, therapy reports, school information, previous assessments, behaviour support plans, hospital discharge summaries, or anything else that helps explain the person's situation. We review these before the interview.
Clinical interview — focused on what matters most. Because background information is gathered beforehand, the interview can focus on clinical interpretation rather than starting from scratch. We ask about daily routines, safety, risks, functional variability, what happens on harder days, what support is in place, and what would happen if that support were not there. Approximately 60 minutes via telehealth.
Clinical reasoning and report writing. The report is written and clinically reasoned by Nisha Bal, an occupational therapist with over 15 years of experience. It draws on the questionnaires, documents, interview and clinical interpretation — and aims to explain functional impact, support needs, risks and recommendations in clear, practical, NDIS-aware language. Delivered within two weeks.

Why questionnaires are not just admin: many people forget details in appointments. Parents and carers often do not realise how much support they provide until specific questions are asked. Adults may mask, minimise, or present better during an interview than they function across the week. Questionnaires give people time to think — and help us use the interview for deeper clarification rather than basic information gathering.

Quality matters

What makes a good
Functional Capacity Assessment report

The value of an FCA report is not its length. It is whether the report explains the person's daily life clearly enough to be useful — for planners, families, support coordinators, therapists, and anyone else who needs to understand what support is reasonably required and why.

A good report should explain the link between impairment, daily function, and support need. It should include real-life examples rather than generic statements. It should identify risks — including what happens when support is not in place. It should consider informal supports and whether they are sustainable. It should make clinically justified recommendations without overstating what the assessment can determine. And it should avoid simply repeating what the family or participant has said without clinical interpretation.

What a good FCA report does
→Explains impairment → daily function → support need in clear, plain language
→Uses real examples from the person's actual life — not generic descriptions
→Identifies risks, including what happens when support is absent
→Considers informal carer support and whether it is sustainable
→Makes recommendations that are proportionate, realistic and clinically justified
→Is written in language that planners, families and support coordinators can actually use
→Is honest — does not exaggerate, and does not understate
Knowing when to seek one

When an FCA may help —
and when something else may be better

An FCA may be worth considering at a range of points — not only when things are in crisis. Some of the most useful assessments happen early, before a plan review, or when something is changing in the person's life or support arrangements.

When an FCA helps — and when another approach may be better
An FCA with Seeds OT may help
Applying for the NDIS and needing functional evidence
Preparing for a plan review — current plan no longer matches needs
Change in function, living situation or support arrangements
Carer exhaustion or concern the support arrangement is not sustainable
Need to explain why current supports are not enough
Key life transitions — leaving school, moving toward adulthood, changes in work or living
Increased safety risks that need to be documented
Another assessment may be more appropriate
Face-to-face functional observation is clinically necessary
Home safety assessment or home modifications are the primary need
Complex assistive technology requiring in-person trial
School or workplace observation is required
Neuropsychological, psychological or speech pathology assessment is the priority
Behaviour support assessment is needed
A multidisciplinary review is more appropriate than a single-discipline FCA
Seeds OT will be honest if we are not the right fit. It is better to say so early than to provide an assessment that does not properly meet the person's needs.

A Functional Capacity Assessment should help others understand what daily life is really like — not just what appears possible from the outside. Done well, it makes a person's everyday support needs visible, explains why support is needed, and helps those needs be heard.
