Our Functional Capacity Assessments take a developmentally informed, neuroaffirming approach to understanding functional capacity over time. Unlike standard FCAs that focus on task performance or static skill levels, our assessments examine how an individual’s neurodevelopmental profile shapes their everyday functioning across environments. Assessments are completed by a Specialist in Autism and Neurodivergence and consider autism as a neurodevelopmental disability, recognising that developmental progress may be uneven across areas. We assess fine motor, gross motor, and fundamental movement skills against developmental age expectations rather than chronological age alone. This ensures capacity is understood within a realistic developmental framework, not compared against neurotypical norms that do not reflect the person’s neurology. Our FCA integrates neuroscience-informed understanding of motor planning, coordination, sensory processing, and nervous system regulation. Differences in motor coordination, balance, proprioception, vestibular processing, and sensory integration are explored in detail, recognising their significant impact on daily living, independence, learning, and participation. Capacity is therefore understood not only in terms of what a person can do, but how much effort, regulation, and support is required to do it. We assess across all six NDIS life domains, clearly linking neurological differences inherent to autistic and neurodivergent cognition with functional impact. Supports are recommended based on developmental stage, sensory–motor profile, and the level of scaffolding required to build motor performance, coordination, and functional independence over time. This approach aligns directly with the NDIS “reasonable and necessary” criteria while remaining grounded in developmental science rather than deficit-based comparison.
