How long does the Miller MFPS take to administer?

• A. 15-30 minutes
• B. 30-45 minutes
• C. 45-60 minutes
• D. 60-90 minutes

Answer: (C)

The time to administer the Miller Function & Participation Scales is a moderate-length session because it includes both the performance tasks and the participation ratings, plus the time for instructions, demonstrations, and scoring. The standard administration duration is about 45 to 60 minutes. This window allows you to smoothly guide the child through the tasks, observe motor performance, and complete the participation rating and scoring without rushing. Some flexibility is reasonable if a child needs a short break or if you take a bit more time for scoring, but 45–60 minutes is the typical, recommended range. Shorter time frames (15–30 minutes or 30–45 minutes) wouldn’t usually allow full administration and reliable scoring, while a window of 60–90 minutes is longer than the standard and typically unnecessary unless special circumstances arise.
