The LSAMP Indiana Alliance program was established in 2002 to increase the number of underrepresented minority students earning STEM degrees. This evaluation assessed the program's progress over five years. Key findings include: 1) while most LSAMP students major in STEM, some fields like computer science and engineering are underrepresented; 2) about a third of students had less than five hours of research experience in their major; 3) LSAMP students are more likely than peers to have a mentor and support network but four in ten lack a major-area mentor. Recommendations focus on ensuring mentors, improving collaboration across institutions, and tracking student outcomes longitudinally.
