Welcome to the Challenge

The Challenge is a dynamic assessment of advanced motor skills. It was designed to extend upon the foundation skills of the Gross Motor Function Measure (GMFM-66) and be used with children with cerebral palsy who are aged 6 years and up, ambulatory without devices (i.e., in GMFCS Level I or II). 

Accessing Challenge Forms and Videos

To access Challenge forms, manuals and training videos, you must complete a training course. If you have taken the Challenge training course, you will have access to the materials on our Challenge Manual and Training Videos page page.

The Challenge comprises skills that:

  • Are considered important for children and youth to be able to perform in school and recreation
  • Focus on impairments of speed, balance and coordination that are typical in children with cerebral palsy in GMFCS Level I
  • Integrate upper/lower limb movements and dual task performance.  

Each of its 25 skills is scored on a 5-point response scale (0 to 4) using item-specific response options described on  the Challenge score form. Test administration takes 45 to 60 minutes and is done on and around the Challenge 10 metre 'track'. Individual item scores enable the physical therapist to discern the areas of strength and challenge for purposes of goal setting and intervention planning. The Challenge should be scored by a pediatric physical therapist who has experience with administering the GMFM-66, and who has taken the Challenge training course and passed the Challenge criterion test.
