During the undergraduate years, involvement in research projects and the guidance of experienced mentors are powerful means of retaining students in S&E.2 Mentors can provide advice, encouragement, and information about people and issues in a particular field. An early exposure to research can demonstrate to students the kinds of opportunities they will encounter if they pursue research careers.

TRENDS IN UNDERGRADUATE AND GRADUATE STUDENT INTEREST IN S&E

When one examines the issue, it becomes clear that there is a great deal of domestic student interest in undergraduate S&E programs. About 30% of students entering college in the United States (of whom over 95% are US citizens or permanent residents) intend to major in S&E fields. This proportion has remained fairly constant over the last 20 years. However, a considerable gap exists between freshman intentions and successful degree completion. Undergraduate S&E programs report the lowest retention rate among all academic disciplines. A National Center for Educational Statistics (NCES) longitudinal study of first-year S&E students in 1990 found that fewer than 50% of undergraduate students entering college declaring a S&E major had completed S&E degrees within 5 years.3 Indeed, approximately 50% of such undergraduate students changed their major field within the first 2 years.4 Undergraduates who opt out of S&E programs are among the most highly qualified college entrants.5 They are also disproportionately women and nonwhite students, indicating that many potential entrants are discouraged before they can join the S&E workforce.6
