Numerous studies have been conducted on the relationship between health-related physical fitness and other physical or psychological variables. However, there is very little research literature concerning the relationship among different components of health-related physical fitness. The present study attempts to develop a Rasch scale to measure primary students' overall health-related physical fitness. With this unidimentional Rasch scale, students' physical fitness levels could be calibrated and traced simply by reference to one overall indicator rather than five separate indicators. The scale is composed of 7 physical fitness tests including 6-min Run, 9-min Run, 1-min Sit-up, Push-up, Sit and Reach, Right Hand Grip, and Left Hand Grip which are designed to assess five components of health-related physical fitness. The data used in this study were collected from pupils of grade 1 to 6 in a Hong Kong primary school. The results showed that the attempt to use a Rasch composite indicator of physical fitness instead of traditional separate indicators was rather promising. Current constraint and further refinement to this scale are discussed in the paper and suggestions to further research are provided.
