DSST (formerly DANTES Subject Standardized Tests) are credit-by-examination tests originated by the United States Department of Defense's Defense Activity for Non-Traditional Education Support (DANTES) program. The program is an extensive series of 30+ examinations in college subject areas that are comparable to the final or end-of-course examinations in undergraduate college courses. These tests are frequently used in conjunction with CLEP (College Level Examination Program) tests by students pursuing college degrees in non-traditional formats. Whereas CLEP tests are almost exclusively used for lower level credit at regionally accredited institutions, DSST's are available for both upper and lower level credit.
