Among students who started college with an interest in majoring in a STEM field, does a student’s race contribute significantly to the chances that he or she will follow through on these intentions? If so, are the effects of race moderated by high school academic preparation and/or key college experiences? If there are racial disparities in persistence rates after controlling for pre-college student characteristics, what are the college factors that contribute to the persistence of under represented racial minority (URM) students? What college experiences and institutional characteristics significantly predict the likelihood that a URM student will follow through on his or her intentions to pursue a degree in STEM?
