RESULTS 



At the completion of each training period, a written test (see Appendix 1 for 

 sample test) was given and the results of these tests were discussed by the 

 class members. The score on this test was one factor used to judge a candi- 

 dates ability to use the unit during their dive . The rebreather training 

 program resulted in a team of aquanauts who individually had a minimum of ten 

 hours supervised water time using the Mark X and a sufficient working know- 

 ledge and understanding of the maintenance and functioning of the rebreather 

 to carry them safely through their mission.
