College Level Examination Program (CLEP)
CLEP gives you the opportunity to receive college credit for what you already know. Earn credit for knowledge you've acquired through course work, independent study, cultural pursuits, travel, special interests, military service schools, and professional development.
The DSST program is an extensive series of 38 examinations in college subject areas that are comparable to the final or end-of-course examinations in undergraduate courses. ACE recommends 3 semester hours of credit per test.
