This study investigated the short- and long-term outcomes of the College-Level Examination Program (CLEP) compared to students who earned comparable credit through the Advanced Placement Program (AP) and through traditional course enrollment. Results are reported with respect to graduation rates, patterns of additional courses taken, academic performance, and SAT scores. Results indicated mixed results across courses (e.g., college algebra, calculus): in some instances the CLEP groups performed better than other matched groups while in other instances there were no differences or differences favoring the AP group.
