In a criterion-referenced measurement of motor ability, criterions and standards corresponding to individual motor development in children were required to evaluate absolutely motor ability improving in PE program. Item response theory (IRT) was applied to motor achievement pattern data measured individual motor skill improvement attained in elementary PE program.
