The LSAMP and LSAMP Bridge to the Doctorate program is aimed at increasing the quality and quantity of students successfully completing science, technology, engineering and mathematics (STEM) baccalaureate degree programs, and increasing the number of students interested in, academically qualified for and matriculated into programs of graduate study. LSAMP supports sustained and comprehensive approaches that facilitate achievement of the long-term goal of increasing the number of students who earn doctorates in STEM fields, particularly those from populations underrepresented in STEM fields. The program goals are accomplished through the formation of alliances. Phase I programs place emphasis on aggregate baccalaureate production. Phase II programs augment the Phase I emphasis with attention to individual student retention and progression to baccalaureate degrees. Phase III programs augment the Phase I and Phase II with attention to aggregate student progression to graduate school entry.
