Functional Capacity Assessments (FCAs) evaluate an individual’s ability to perform daily activities and function within their environment, often used in clinical, educational, and rehabilitation settings. Two common tools for measuring functional capacity are the Vineland-3 Adaptive Behavior Scales and the PEDI-CAT (Pediatric Evaluation of Disability Inventory – Computer Adaptive Test).

**Vineland-3** is a standardized tool for assessing adaptive behavior, including communication, socialization, daily living skills, and motor skills. It is particularly useful for individuals with intellectual and developmental disabilities and autism. The assessment can be administered via interviews, teacher ratings, or self-reports, and it is suitable for individuals from birth to adulthood. The Vineland-3 helps diagnose disabilities and create individualized education plans (IEPs).

**PEDI-CAT** is a computer-adaptive test designed to measure functional performance in children and adolescents with disabilities. It evaluates daily activities, mobility, social/cognitive skills, and responsibility. The PEDI-CAT uses a computer algorithm for adaptive testing, making it efficient and precise. It is appropriate for children and youth (birth to 21 years) and is often used in hospitals, schools, and early intervention programs.

Choosing between the two depends on the individual’s needs: Vineland-3 is broader and spans all ages, while PEDI-CAT focuses specifically on children and adolescents, offering a more targeted approach for assessing developmental progress. Both tools guide interventions to enhance independence and quality of life.
