This chapter is based on a literature review to gain insight into the critical components of a STEM Student Success Model for underrepresented minority (URM) undergraduate (UG) science, technology, engineering, and mathematics (STEM) students since many articles reviewed focused on the equity, inclusion, and diversity of URM STEM students who are most likely to need help in their studies. The salient components of the model are learning with peers, interactions with faculty, STEM employability skills, and a supportive campus environment. The success of URM STEM students is necessary to address the preparation of URM graduates for the STEM workforce which in turn, will help address the workforce shortage in STEM fields if the United States is to maintain a competitive advantage in STEM disciplines.
