Power-Mobility Community Driving Assessment (PCDA)

Power-Mobility Community Driving Assessment (PCDA)


This interview and performance-based assessment evaluates a person’s ability to safely operate a power-mobility device (scooter or powered wheelchair) in his/her community. This assessment is not to be used for evaluation of safe driving of an automobile. However, I decided to include this assessment due to the current need for safe driving not only in automobiles but also while individuals maneuver through their community pursuing their IADLs.

This assessment was developed by Occupational Therapists for Occupational Therapists to evaluate their clients’ driving performance in their communities and to enable the assessor and driver to determine which areas of driving are problematic so that these can be addressed through a training program, environmental modification, and/or device modification.7
