From “Science, Technology, Engineering, and Mathematics (STEM) Pathways: High School Science and Math Coursework and Postsecondary Degree Attainment,” by Tyson, Lee, Borman and Hanson [Journal of Education for Students Placed at Risk, 12(3), 243–270 (2007)]:
Our findings reveal the importance and value of taking high-level coursework in both mathematics and science during high school. Enrollment and attainment in physics and calculus is particularly important for all students with respect to obtaining a STEM degree down the road. Somewhat surprising and most encouraging, the results of our analyses show that minority students who are prepared for STEM degree attainment by virtue of taking high-level science and mathematics courses, particularly calculus, chemistry, and physics at the highest levels, are more likely to persist through STEM coursework in college than their White counterparts and obtain a STEM degree. Those African American students with higher level coursework preparation who persevere in pursuing the pathway toward obtaining a baccalaureate degree are just as likely to obtain STEM degrees as their White peers who also complete baccalaureate degrees. Similarly, Hispanic students with advanced level course preparation are also more likely than White students to persist to obtain a STEM degree.
