Two of the biggest credit-by-exam programs, side by side. Here is how CLEP and DSST really differ, and how to pick the right one for your degree.
Last updated: July 22, 2026
Jump to the comparison table →If you are trying to test out of college courses, you have almost certainly run into two acronyms: CLEP and DSST. Both let you earn real college credit by passing a single exam instead of sitting through a full semester, and both can save you serious time and money. So which one should you take?
The honest answer is that it is rarely one or the other. CLEP and DSST overlap in some subjects and diverge in many others, and the program that is right for you depends mostly on which exams your college accepts and which subjects you need. We cover both programs at Powerhouse Prep, so we have no reason to steer you toward one over the other. This guide lays out the real differences, then helps you decide when each one makes sense.
CLEP stands for the College-Level Examination Program. It is run by the College Board, the same nonprofit behind the SAT and the AP program. There are 34 CLEP exams spanning business, composition and literature, history and social sciences, science and mathematics, and world languages. Most are designed to mirror a common introductory college course, so passing one is like testing out of a freshman-level class such as College Algebra, Introductory Psychology, or American Government. CLEP has been around for decades and is the more widely recognized of the two programs.
DSST originally stood for the DANTES Subject Standardized Tests. It was created for the military through DANTES (the Defense Activity for Non-Traditional Education Support) and has since grown into a program open to everyone. The exams are owned and administered by Prometric. There are more than 30 DSST titles across business, humanities, math, physical science, social sciences, and technology. DSST is known for offering subjects you will not find in the CLEP catalog, such as Substance Abuse, Criminal Justice, and Organizational Behavior, and for including some upper-level material that can count toward junior and senior year requirements at certain schools.
Here is how the two programs stack up on the factors that actually affect your decision. Figures are current as of 2026; always confirm exam-specific details with the official program and with your college.
| Factor | CLEP | DSST |
|---|---|---|
| Administrator | College Board (nonprofit behind the SAT and AP) | Prometric, under the DANTES program originally created for the U.S. military |
| Number of exams | 34 exams | More than 30 exams |
| Exam fee (2026) | $97, plus a test-center or remote-proctoring administration fee | $100, plus a test-center administration fee |
| Credits per exam | Usually 3 semester credits; a few exams (such as full College Composition) can be worth up to 6 | Usually 3 semester credits; some upper-level titles may count differently by school |
| Question format | Multiple choice with 5 answer choices (some exams include other question types) | Multiple choice with 4 answer choices |
| Time allowed | 90 minutes for most exams | 2 hours |
| Scoring scale | 20 to 80; ACE recommends 50 to earn credit on most exams | 200 to 500; ACE recommends 400 on most exams (a few use a higher cut score) |
| College acceptance | Accepted at 2,900+ colleges and universities | Accepted at 1,900+ colleges and universities |
| Level of material | Mostly introductory, freshman-level courses | Mix of introductory and upper-level subjects |
| Subject strengths | Broad general education: algebra, psychology, government, literature, composition, world languages | Niche and applied subjects CLEP lacks: criminal justice, substance abuse, organizational behavior, personal finance, technology |
| Military funding | Can be DANTES-funded for eligible service members | Can be DANTES-funded and is deeply rooted in the military education system |

CLEP is usually the better starting point when:
If your goal is to clear the first year of general-education requirements as cheaply and quickly as possible, CLEP is often where you start. You can browse every subject we cover on our CLEP study guides and practice tests page.
DSST is often the better choice when:
If you are chasing a specialized requirement or upper-level credit, DSST earns its place in the plan. See everything we cover on our DSST study guides and practice tests page.
It is tempting to treat CLEP versus DSST as a head-to-head contest with one winner. In practice, the deciding factor is almost never the program itself. It is your college's credit-by-exam policy. A school might accept CLEP College Algebra for three credits but require a higher score than ACE recommends, accept a specific DSST exam only as an elective, or cap the total number of exam credits you can apply toward your degree. Two students at two different schools can make opposite, equally correct choices.
Before you register for anything, pull up your college's transfer-credit or credit-by-exam page, or email your academic advisor, and confirm three things for the exact exam you are considering: that the school accepts it, what minimum score it requires, and how the credit will apply (general education, major, or free elective). Do that first, and the CLEP-versus-DSST question usually answers itself.
Because the two catalogs overlap only partly, the smartest strategy for many students is to combine them: take CLEP for the general-education subjects it covers best and DSST for the specialized subjects only it offers, staying within your school's credit cap. You do not have to be loyal to one program.
Most prep sites specialize in one program or the other, which quietly nudges you toward whatever they happen to sell. We are one of the few brands that covers both CLEP and DSST, so we can give you a straight answer about which exam fits your degree and then actually help you prepare for it.
Every subject we support comes with a free overview, a practice quiz to gauge where you stand, and pointers to solid resources to finish studying. Start with the catalog that matches your plan:
Not sure yet? That is normal. Skim both catalogs, note which exams line up with the courses you still need, then confirm acceptance with your college.
Full disclosure: this one is ours. The Powerhouse Prep iOS app puts every CLEP and DSST exam in a single subscription, with real timed practice exams and a live pass-readiness score so you are not guessing whether you are actually ready to book the test. It is iPhone-only for now, and there is a 7 day free trial so you can judge for yourself.

DSST covers a mix of introductory and upper-level subjects, gives you four answer choices, and allows two hours. Difficulty depends far more on the specific subject and how well it matches what you already know than on the program itself. A well-prepared student passes either one.
Both CLEP and DSST are evaluated by the American Council on Education (ACE), and a passing score on either typically converts into the same kind of college credit, usually three semester hours for a lower-level exam. The catch is acceptance: each college decides which exams it will honor and what score it requires. Many schools accept both, some accept only one, and a few accept neither. Always confirm with your registrar before you register.
As of 2026 the CLEP exam fee is $97 and the DSST exam fee is $100, in both cases paid to the program itself. Most test centers add their own administration or proctoring fee on top, commonly in the range of roughly $20 to $40. Active-duty military members and many of their dependents can have DSST exams (and CLEP exams) funded through DANTES, which can make them free.
Most single-subject CLEP and DSST exams are worth three semester credits, roughly one college course. A handful of broader CLEP exams, such as the full College Composition exam, can be worth up to six credits at some schools. The exact number of credits and whether they count as general education, elective, or major requirements is set by your college, not by the testing program.
Yes. Many students mix and match, using CLEP for the subjects it covers well (like College Algebra, Introductory Psychology, or American Government) and DSST for subjects CLEP does not offer (like Substance Abuse, Criminal Justice, or Organizational Behavior). As long as your college accepts credit from both programs and you stay within its cap on credit-by-exam, combining them is a common and efficient strategy.
CLEP exams are scored on a 20 to 80 scale, and ACE recommends a score of 50 as the credit-granting minimum for most exams. DSST exams are scored on a 200 to 500 scale, and ACE recommends a passing score of 400 for most subjects, though a few use a higher cut score. Your college can set its own required score at or above the ACE recommendation, so check its policy.
