on the basis of their sonar ability, and entrance standards 

 were set for all courses given by C omSub Train Pa c Q Thanks to 

 the work of this group, the waste of training facilities on 

 unouslified men was largely eliminated , 



In the training of submarine personnels profiting by the 

 mistakes made during the antisubmarine warfare experience, 

 the Division S training groups were able to follow a more 

 orderly procedure, The development of each new training pro- 

 gram included (1) analysis of training requirements, (2) a 

 survey of existing facilities, (5) the planning of curricula, 

 (4) the training of instructors, (5) the development of 

 achievement tests, (6) the preparation of training aids, (7) 

 the construction of synthetic trainers, and (8) field service 

 to introduce the new program , Programs developed in accord- 

 ance with this pattern were successfully carried out for 

 sonar, voice communicat ions and radar training. 



During 1944 nnd early 1945, Division 6 training groups 

 assisted in the planning and establishment of new basic 

 courses for sonar operators at Pearl Harbor, New London and 

 San Diego o They set up a basic maintenance course at New 

 London and refresher courses for operators and maintenance 

 men at Pearl Harbor, Perth and New London „ Special courses 

 were established at a number cf other submarine bases „ 



Division 6 laboratory representatives prepared training 

 materials and introduced courses at submarine bases in both 

 the Atlantic and Pacific for instruction in the use of JP 

 sonar equipment which had been developed by the CUDWR lab- 

 oratory. At a later date, courses were developed for train- 

 ing in the use of other sonar equipment which had been de- 

 veloped by the Division 6 laboratories, Training material 

 was distributed to the Naval personnel prior to the instal- 

 lation of equipment on the submarines, so that when the 

 equipment finally was installed, the men, who would use it, 

 would already have a background of information, 



ComSubsLant asked Division S for aid in developing a 

 training program in voice communications, To meet the re- 

 quest, Division 6 enlisted the aid of two ether NDRC groups, 

 the Psycho-acoustics Laboratory at Harvard University and 

 Project N-109, the Applied Psychology Panel, The three 

 groups collaborated in a program which involved the standard- 

 ization of phraseology and procedures used in voice communica- 

 tions and the establishment of training courses for officers 

 and men. The program started in April, 1944, and continued
