This report describes a longitudinal evaluation of an on-going 5-year program at the University of Michigan to improve minority student retention and academic performance. The Undergraduate Research Opportunity Program (UROP) creates research partnerships between first- and second-year students and faculty researchers, and provides peer counseling, workshops in learning skills, and research peer groups. The evaluation compared students in the program with students matched for grade point averages and college entrance examination scores who had applied to the program. Among evaluation findings are: (1) UROP students had an attrition rate 32 percent lower than underrepresented students university-wide; (2) African-American students in UROP showed an attrition rate 51 percent lower than control group students; (3) participation in UROP resulted in grade point averages some 6 percent higher than all students; and (4) UROP appeared to positively affect student self-esteem, coping strategies, learning behaviors, and expectations about academic performance. Individual sections of the report present an executive summary, an overview of the project, and a description of the project's purpose, background and origins, major components, and evaluation/results. Appendices include the UROP brochure, newsletter, and faculty handbook, the survey instruments, and a draft paper titled "Undergraduate Student-Faculty Research Partnerships Affect Student Retention" (Biren A. Nagda and others). (DB)
