Swarthmore College is studying the migration of undergraduates into and out of STEM disciplines. In 2009 the Foundation supported efforts by the Thurgood Marshall College Fund (TMCF), the umbrella organization of 47 public, historically black universities, law schools and medical schools, to enable them to explore the possibility of some of their member campuses joining the Swarthmore-led STEM migration project or launching a similar project. Fund from this follow-on grant will enable 20 of the TMCF member campuses to join the Swarthmore-led project. The addition of 20 TMCF campuses to the STEM migration project would provide the basis for these campuses to improve STEM retention, provide a broader basis for each of the 44 campuses to compare its own performance with that of others, greatly expand the project's data on African American students, and facilitate further fundraising to sustain the project to which both Swarthmore College and TMCF are committed.
