Because the first-term attrition rate for enlisted Marine Corps women is nearly 50 percent, or about twice that for comparable men, a study was undertaken to identify factors that might be related to this high attrition rate. During the study, the following three data sets were analyzed: historical master files and recruit accession management system files, a three-year follow-up on a recruit-training attrition study of 196 women that used expectations to predict attrition, and a job satisfaction survey administered to 1,369 Marine Corps women. While the results of the study indicated that most of the difference in post-recruit training attrition between men and women was due to pregnancy, the data did not support the hypothesis that women are becoming pregnant in order to be discharged. Because factors associated with Marine Corps experience, particularly in the work setting, appeared to be related to attrition, recommendations were made calling for additional investigation of these experience factors. Other recommendations emerging from the study included training in sex education and life-decision making, placement of women in units with at least one other woman, and use of information on women's interests in sports and nontraditional activities when recruiting.
