Miller Function and Participation Scales (M-FUN)

The M-FUN asks a different question from most motor tests: not just what a child's body can do, but whether their motor skills are getting in the way of taking part at school and at home.

Two halves make up the assessment. The performance component uses game-like activities — Amazing Mazes, Race Car Game, Clay Play, Make a Fish, Bouncing Ball Game — to produce scores in three areas: visual motor, fine motor, and gross motor. Each child works through an individual workbook simulating early school tasks like writing, drawing, tracing, and cutting. The participation component adds three observation checklists completed for the test session, the home, and the classroom, so the same child is described from three vantage points.

Licensing Notes: Workbooks, record forms, and observation checklists are consumables sold in packs of 25, in two age bands (2:6–3:11 and 4:0–7:11). Reproduction requires publisher permission.

Learn More: The M-FUN was built on the ICF framework and AOTA's Practice Framework. Standard scores are only available when every game in a domain has been completed, so partial administration limits what you can report.
