In order to compare their physical fitness, the UNIQUE Physical Fitness Test was administered to 203 retarded and nonretarded subjects with cerebral palsy from both segregated and integrated settings throughout the United States. The test was administered to subjects between the ages of 10 and 17 by professional persons prepared as field testers. Subjects were free from multiple handicapping conditions other than mild mental retardation and cerebral palsy. Regardless of intellectual classification, older subjects significantly exceeded the performance of younger subjects on dominant grip strength. Regardless of intellectual classification, older subjects significantly exceeded the scores of younger subjects on the softball throw and flexed arm hang. No significant differences between retarded and nonretarded subjects at the .01 level of significance were found on any of the test items on the UNIQUE test. The factor structures of both retarded and nonretarded groups were identical with regard to the items that loaded on specific physical fitness factors.
