This study was part of a longitudinal study of factors related to pers
istence in a science-related career. Participants (N = 173; 97 women a
nd 76 men) were a subsample of matched participants from the 1980 and
1990 phases of data collection in the midwestern United States who in
1980, while in high school, aspired to a science, math, or technology
career. By 1990, 36% of women and 46% of men had persisted in a scienc
e-related career. Structural equation model testing indicated that for
women persistence was related to the number of elective high school s
cience courses taken and that women who had higher career commitment w
ere more likely to have switched aspirations to another career field.
For men, persistence was related to their 1980 and 1990 career aspirat
ion level and needing and obtaining financial support for college. For
men these relationships also incorporated the largely indirect effect
s of high school science grade point average. implications for counsel
ing include encouraging interested adolescent girls to take elective s
cience courses and nurturing aspiration level in adolescent boys who h
ave science ability and are interested in a science career.
