The purpose of this investigation was to determine the test-retest reliability of the Balke-Ware Treadmill; Modified Physical Working capacity Test (bicycle ergometer); Canadian Step Test; and Cooper Twelve-Minute run-walk, in measuring the cardiovascular efficiency of from a sheltered workshop in Hays, Kansas. The subjects ranged in age from 25 to 55 years and IQ’s ranged from 41 to 72 (mean IQ-54). The group was kept intact and was tested on each test-retest protocol. A retest measure was used to determine the test/retest reliability of the administrative personnel utilized in monitoring heart rates. Data were analyzed by use of Person product-moment correlation. The findings revealed a significant relationship by each of the personnel and an overall intra-tester reliability score of r=.921, df =7. To further strengthen these findings, analysis of variance was used to determine the significance of differences between the means of manual heart rate monitoring and that recorded by the AMF Benchmark Quantum XL Fitness between the two methods (p<.05). Based on the predicted oxygen uptake of each session, a reliability correlation was conducted for each of the four protocols. Pearson product-moment correlation revealed significance for each of the four test-retest protocols (p
