Abstract
Valid and reliable tests were developed for the purpose of measuring selected fundamental skills of children in grades 1 to 6. The skills tested were throwing, catching, kicking, batting, jumping, and running. For each test and each sex an analysis of the difference between mean scores for one grade and the mean scores for the succeeding grade showed an upward trend frmo grade to grade, except between grades 5 and 6. Performance norms were computed on the basis of the obtained results. Percentile ranks were computed for each test according to sex and to grade.
