Postsecondary educational credit recommendations for formal courses offered by the Coast Guard, the Marine Corps, the Navy, and the Department of Defense are provided in this third of a three-volume set. (Other volumes cover courses offered by the Army and by the Air Force. See note.) Also included are credit recommendations for Navy general rates and ratings (occupational categories in the Navy Enlisted Rating Structure). Following sections on the use of the guide, formal course and Navy rating exhibits are listed. Each course exhibit contains such information as present and former course titles, course number, location, length, objectives, description of instruction and subject areas covered. Each Navy rating exhibit includes such information as official Navy title of the general rating, description of skills, knowledge and competencies for that rating, and recommendation for educational credit. Credit recommendations expressed in semester hours are given in four categories: vocational certificate, lower division baccalaureate/associate degree, upper division baccalaureate and graduate degree. The appendixes contain the following information: historical development of the Guide, which courses can be found in the Guide; description of the evaluation system for credit recommendations; and definitions and guidelines on the categories of education credit, the semester hour standard; background on Navy enlisted occupational fields and ratings, Naval occupational standards, and Naval standards; and Navy occupational title index.
