Abstract. This research examined past, present, and future factors that might be related to persistence in engineering for women and men. Students currently or formerly enrolled in an undergraduate engineering program completed the Engineering Career Survey which assessed factors included in general models of college student change (e.g., background characteristics, interactions with socializing agents). Results indicated that: (1) present factors were more important than past or future factors in distinguishing between engineering persisters and nonpersisters, (2) few factors distinguished between women and men who persisted, or between women and men who did not, and (3) the best predictor of engineering persistence for both sexes was grade point average, although subsequent predictors depended on gender. Limitations and implications for future research are discussed.Vocational educators and society in general are concerned about the anticipated shortage of engineers in the next century (National Science Foundation 1989, 1990 Office of Technology Assessment 1985Poole 1990). ~ Partly in response to this concern, researchers have begun to identify factors that influence the choice of engineering as a career, and persistence in engineering once the choice has been made. Most of the research has focused on academic factors in the individual's past (e.g., high school grade point average) that influence the choice of engineering as a career (e.g., Lemkau 1979;Shell et al. 1983). Our research focused on both academic and nonacademic factors in the individual's past, present and future that might influence persistence in engineering. Of particular interest was whether different factors were important to engineering persistence for women and men.General models of college student change were used to identify factors that might be important to engineering persistence. Tinto (1975; theorized that students enter college with varying patterns of personal, family and academic characteristics and skills, including dispositions and intentions with respect to persistence. Through interaction with the structures and members of the academic and social systems, these dispositions and intentions are continually modified and reformulated. Satisfying and rewarding interactions lead to integration and persistence. Other models have similarly emphasized the importance of student's integration into the college community in predicting persistence (Astin 1985(Astin , 1985Pace 1984;Theophilides et al. 1984; see Pascarella and Terenzini 1991, for a review). Pascarella (1985) has offered a general model of college student change that is applicable to multi-institution studies: because it considers institutional structural characteristics as well as factors considered by Tinto (1985). Pascarella's model
