An adaptive physical education program was implemented for two special classes of educable mentally retarded children, grades K-3 in California. Children from a regular kindergarten class also participated in the program. The program operated for 5 months, with children receiving motor skills training 40 minutes per day, 4 days per week. Analysis of pre- and post-test scores on the Bruininks-Oseretsky Test of Motor Proficiency revealed that Ss increased skills in seven of the eight subtests with a statistically significant increase in strength. Normal kindergarteners who participated in the program increased skills in six subtests with statistically significant increases in running speed and agility and in strength. Student interest and participation in the program were high. (CL)
