The present paper describes the results of a two-year project aimed at developing a motor performance test instrument for a motor performance award scheme for kindergarten children to be organized by the Hong Kong Childhealth Foundation. The subjects were 1404 K1 to K3 children, aged three years, three months to six years, ten months. A set of tests developed for Hong Kong kindergarten children was administered to measure their gross motor proficiency. Boys were superior to girls on agility and throwing. Girls performed better than boys on static balance. It was found that a marked improvement in agility was found at the age of 5.5 years. After four years of age, children's static balance also improved. As expected, young children's overall gross motor performance improved, and this was seen as being age-related. The modified set of tests for motor performance was found suitable for use in measuring gross motor performance of children participating in the award scheme for Hong Kong kindergarten children.
