This report presents research findings for Advanced Placement (AP) student success at the college level. Strong AP programs in high schools, coupled with strong AP policies at colleges, support many positive outcomes for students. Multiple research studies have confirmed that AP students who earn credit and advanced placement for the corresponding introductory college course: (1) Perform well in subsequent college courses in the discipline; (2) Are more likely to major in their AP subject or a related discipline; (3) Take more--not less--college course work in the discipline.; (4) Are more likely to graduate within five years; and (5) Can develop an interest in STEM subjects that leads to a STEM major in college. Key findings for each of these 5 areas are presented in this report.
