This study was undertaken as a quantitative description of graduate degree holders within the Air Force line officer force; specifically, those on active duty between 1961 and 1968. Basic data sources were the Uniform Officer Record (UOR) and the UOR reformat, a historical research file maintained by the Personnel Research Division. Records of officers on active duty as of June 1968 were examined to determine how and when they obtained their degrees, and the academic specialties and degree levels involved. The population was also examined at different times during 1961-67 to determine distributions and growth rates among the various duty occupational groups. Retention rates for line officers with graduate degrees were obtained and compared with retention rates for all line officers during that period. Information reflecting the distribution by rank of the graduate degree holders for 1961 and 1968 was also given. (Included are 22 tables and charts, group designations from UOR files, and additional information on graduate degree holders within the line officer hierarchy.) (Author/LY)
