Product Details

STAY IN THE KNOW! Request to 'stay in the know' and we'll provide valuable updates on this new assessment throughout 2020!

The PEDI-CAT measures abilities in four domains:

  • Daily Activities
  • Mobility
  • Social/Cognitive
  • Responsibility - measures the extent to which the caregiver or child takes responsibility for managing complex, multi-step life tasks.

Response Scales

  • For the three Functional Skills domains of Daily Activities, Mobility, and Social/Cognitive, children's ability is rated on a 4 point Difficulty Scale with responses ranging from "Unable" to "Easy."
  • The Responsibility domain has its own 5 point Responsibility Scale with responses ranging from 'Adult/caregiver has full responsibility; the child does not take any responsibility' to 'Child takes full responsibility without any direction, supervision or guidance from an adult/caregiver'.
  • Unique Item Maps represent a reasonable, sequential pattern of functional skills consistent with children's development and recovery of function and transfer of responsibility from adult to child throughout childhood and young adulthood.


  • Identification of functional delay
  • Examination of improvement for an individual child after intervention
  • Evaluation and monitoring of group progress in program evaluation and research
  • Can be used on multiple occasions for the same child (e.g. initial, interim, discharge and follow-up) and there is no minimum time that must pass between assessments
  • Scaled scores can be used for out-of-age (criterion referenced) assessment
