Many autistic adults walk out of a Functional Capacity Assessment with a report that systematically under-states their support needs. The reason is almost always the same — masking went undetected.
The Problem With Standard FCAs for Autistic Adults
A masked autistic participant in a clinical interview can appear to function adequately. They make eye contact, respond appropriately to questions, summarise their week coherently. The clinician then writes a report that captures this presentation — and systematically under-states the participant's real-world functional needs. This is not the clinician's fault, but it is a systemic problem with assessment frameworks not designed for autistic adults.
What Masking Actually Looks Like
Masking is the conscious or subconscious suppression of autistic behaviours to fit social expectations. In an interview, masking may look like forced eye contact, scripted small talk, suppressed stimming, masked sensory distress and exhaustion that becomes visible only after the session ends. Many autistic adults have been masking since childhood and have limited insight into how much energy it actually costs them.
Capturing the Real Picture
A defensible FCA for an autistic adult uses three explicit techniques: (1) collateral input from people who observe the participant in unmasked contexts (partners, family, close friends, support workers); (2) explicit questioning about post-demand recovery — what happens after high-demand environments like work, school, social events; and (3) longitudinal data — how the participant's capacity changes across a typical week, month and year.
Autistic Burnout
Autistic burnout is the cumulative impact of sustained masking and overload. It can present as months or years of dramatically reduced capacity — loss of speech, withdrawal from social contact, inability to maintain employment, regression of self-care skills. Autistic burnout is not depression (though it can co-occur). It is a distinct phenomenon that the NDIA increasingly recognises as a major driver of functional need in autistic participants.
Sensory Profile as a Funding Driver
Sensory processing differences are a defining feature of autism for many participants. A strong FCA documents sensory profile across all sensory modalities — auditory, visual, tactile, olfactory, gustatory, vestibular, proprioceptive and interoceptive. Specific triggers, recovery requirements and the practical impact on community participation, employment and daily living should all be captured.
Executive Functioning and Self-Management
Executive function difficulties — initiation, planning, organisation, working memory, time management and emotional regulation — are common in autistic adults and frequently dramatic in their functional impact. The FCA should document these in measurable, behaviour-specific terms, with examples that demonstrate the gap between theoretical capacity and consistent real-world performance without external structure.
Common Funding Outcomes
A strong FCA for an autistic adult often supports capacity building in social skills and communication, sensory regulation supports and equipment, executive function coaching, 1:1 community access support, in-home support for daily living and routine maintenance, and allied health (OT, psychology, speech). Where the profile is complex — autism with intellectual disability, autism with significant behaviours, or severe autistic burnout reaching the threshold for full-time support — the FCA can also support ILO Stage 1, SIL or SDA application.
Affirming Practice
Identity-first language (autistic adult) is preferred by the majority of the autistic community, unless the individual indicates otherwise. Stimming, special interests and autistic communication styles should not be pathologised. Masking-promotion interventions should not be recommended. Direct, literal language should be used in interview, with written agendas and pre-shared question lists where helpful.
