If you've been asked to organise a Functional Capacity Assessment (FCA) for your child or young person, you may be wondering what it actually involves — and how it differs from other assessments they may have had in the past.
A Functional Capacity Assessment looks at how a child or young person manages and participates in everyday life.
Rather than focusing only on a diagnosis or a score on a standardised assessment, an FCA considers the person's strengths, challenges and support needs across everyday activities and environments.
At Kids World, we want an FCA to help tell the story of the whole child or young person — what they can do, what they find difficult, what support they need and why.
What Does “Functional Capacity” Mean?
Functional capacity refers to a person's ability to carry out the activities that are part of their everyday life.
For a child or young person, this may include things such as:
Getting dressed and managing personal care
Eating and mealtimes
Toileting and hygiene
Moving around safely
Communicating needs and preferences
Managing emotions and regulation
Planning, organising and completing everyday tasks
Participating at school
Playing and participating in leisure activities
Developing and maintaining relationships
Participating in family and community life
Developing independence as they get older
Importantly, an FCA isn't simply about asking “Can they do it?”
We also want to understand how they do it.
Do they need prompting? Does an adult need to initiate the task? Can they complete it independently but only with considerable effort? Can they manage it in one environment but not another? What happens when they're tired, overwhelmed or under pressure?
These details can make a significant difference to our understanding of a person's functional capacity.
Why Might a Functional Capacity Assessment Be Needed?
An FCA may be requested when a detailed understanding of a child or young person's everyday functioning and support needs is required.
For families accessing the NDIS, an FCA may provide evidence about the person's functional strengths, the areas in which they require assistance and the supports that may help them participate more independently and meaningfully in everyday life.
It may also help identify areas where further intervention, equipment, environmental modifications or support may need to be considered.
An FCA should not simply be a document describing everything a child cannot do. A good assessment should provide a balanced picture of strengths as well as support needs and explain the context in which difficulties occur.
How Is a Paediatric FCA Different?
Children are still developing.
This makes assessing functional capacity in childhood different from assessing an adult whose skills and responsibilities are relatively established.
We need to consider what would reasonably be expected for the child's developmental stage while also recognising that chronological age doesn't tell us everything about an individual child's capacities.
We also need to understand the role parents and carers ordinarily play at that age.
For example, all young children require significant assistance from adults. The relevant question may therefore be whether a child requires substantially more support, supervision or prompting than another child of a similar age, and why.
As children move into adolescence, the focus may increasingly include developing independence, managing personal care, organising daily routines, accessing the community, preparing for work or further education and planning for adulthood.
Looking Beyond What We See
One of the most important parts of an FCA is understanding why a person may need support.
Consider a young person who needs repeated reminders to get ready in the morning.
Simply writing:
“Requires prompting for morning routine”
doesn't tell us very much.
We may need to understand whether the difficulty relates to working memory, planning and organisation, sensory processing, motor skills, regulation, interoception, understanding the sequence of the task or another factor.
Similarly, a child may technically be capable of dressing themselves but need an adult present throughout the process to keep them engaged and moving through each step.
Understanding the underlying factors gives a much clearer picture of the person's actual support needs.
What Areas May Be Considered?
Every FCA is different, but an occupational therapist may explore areas such as:
Self-Care and Daily Living
This may include dressing, bathing, grooming, toileting, eating, sleep routines, managing belongings and other everyday activities.
Sensory Processing and Regulation
We may consider how a person responds to sensory information and how regulation influences their ability to participate in everyday activities and environments.
Executive Functioning
Planning, organisation, working memory, task initiation, attention, time management and flexibility can have a significant effect on independence.
Motor Skills and Mobility
This may include coordination, motor planning, fine motor skills, gross motor skills, physical access and the person's ability to move safely within their environments.
Communication and Social Participation
We consider how the child or young person communicates their needs, participates with others, develops relationships and navigates social environments.
Learning and Participation
An FCA may explore how the person participates at school or in other learning environments and the support they require to access activities and routines.
Community Participation and Independence
For older children and adolescents, this may include using transport, accessing shops and services, managing money, preparing food, staying safe in the community and developing skills for increasing independence.
How Does Kids World Approach an FCA?
Kids World primarily provides Functional Capacity Assessments for children and young people aged 0–18 years. Assessments for older adolescents or young adults may be considered in exceptional circumstances.
Our approach is strengths-based, neuro-affirming and relationship-focused.
We don't want to assess a child simply by comparing them with a list of things they “should” be doing.
We want to understand how they think, feel, communicate, learn and participate — including what they do well, what requires additional effort and where support makes a meaningful difference.
Our occupational therapists also use the DIR® model (Developmental, Individual-differences, Relationship-based) to inform our understanding of the child.
This includes considering their Functional Emotional Developmental Capacities (FEDCs), individual sensory and motor processing differences, regulation, relationships and how these factors may influence participation in everyday life.
What Does the Assessment Involve?
An FCA is much more than completing a questionnaire or administering a standardised assessment.
Depending on the child or young person and the purpose of the assessment, the process may include:
Reviewing relevant background information and reports
Detailed discussion with parents or carers
Meeting with and observing the child or young person
Exploring everyday routines, strengths and areas of difficulty
Standardised assessments or questionnaires where appropriate
Considering sensory processing, regulation and executive functioning
Reviewing the level of prompting, supervision or physical assistance required
Liaising with other professionals where appropriate and with consent
Considering how support needs vary between environments
Clinical analysis and preparation of a comprehensive written report
The assessment process is tailored to the individual rather than using exactly the same combination of assessments for every person.
Why Aren't Standardised Assessment Scores Enough?
Standardised assessments can provide valuable information, and we use them when clinically appropriate.
However, a score doesn't always capture the complexity of everyday life.
A questionnaire might tell us that a young person has difficulty with daily living skills. The occupational therapist's role is to interpret that information alongside interviews, observations, developmental information and clinical reasoning to understand what that difficulty actually looks like in the person's life.
We are particularly interested in the difference between what someone can do under ideal circumstances and what they can reliably and independently manage in everyday life.
The Importance of Parents and Carers
Parents and carers often hold an enormous amount of information about their child's functioning.
They see what happens before school, after a demanding day, during family activities, when routines change and when a child is tired or overwhelmed.
This information is important.
During an FCA, we want to understand not only what parents do for their child, but also the level of support, prompting, planning and supervision happening behind the scenes.
Sometimes families provide so much support as part of everyday life that it becomes difficult to recognise just how much assistance is actually required.
An FCA can help make that support visible.
A Functional Capacity Assessment Should Tell a Story
A good FCA shouldn't read like a collection of test scores.
It should bring together information from the child or young person, their family, assessment tools, observations and the occupational therapist's clinical reasoning to provide a clear picture of everyday functioning.
It should help the reader understand:
Who is this person?
What are their strengths?
What do they want and need to participate in?
What makes participation difficult?
What support do they currently require?
What could help them develop greater participation and independence?
Ultimately, the purpose is to provide a meaningful picture of the child or young person's real life, not simply their performance during an assessment.
Functional Capacity Assessments at Kids World
Kids World provides paediatric Functional Capacity Assessments from our clinics in Lane Cove, Sydney.
Because understanding a child over time can provide valuable context for an FCA, our assessment process considers the information available about the child, their history and their everyday environments.
If you're considering a Functional Capacity Assessment for your child or young person, our team can discuss the purpose of the assessment, the information required and whether Kids World is an appropriate service for their needs.
