Students' proficiency in three object control and three locomotor skills were assessed in 2000 (M age = 10.06 years, SD = 0.63) in New South Wales, Australia and in 2006-07 (M age = 16.44 years, SD = 0.64). In 2006-07, 266 students, 138 girls (51.9%) and 128 boys (48.1%), had at least one skill reassessed. Boys were more object control proficient than girls. Childhood object control proficiency significantly predicted (p = 0.001) adolescent object control proficiency (r[squared] = 0.39), and, while gender was significant (p = 0.001), it did not affect the relationship between these variables (p = 0.53). Because childhood object control proficiency is predictive of subsequent object control proficiency, developing skills in childhood is important. (Contains 2 tables and 1 figure.)
