How many questions are on the ASVAB, and how long is it?

The short answer

There is no single number, because the ASVAB exists in several versions. All figures below come from the official What to Expect page unless another source is linked.

The computer version is used at every MEPS and at most MET sites, so it is the version you are most likely to meet at a proctored session. Your recruiter can tell you which one you are scheduled for.

CAT-ASVAB: questions and time per subtest

The computer test is adaptive: after a right answer you usually get a harder question, after a wrong one an easier one, which lets it reach a precise score with shorter test lengths than the paper test. Here is the official table, in the order the subtests are given:

Adding up the rows gives the figures below. They are our own arithmetic, not official numbers: officialasvab.com does not publish totals for the computer version.

• Scored questions: 135 across the ten subtests.
• Time limits without tryouts: 197 minutes if you used every minute of every subtest.

In practice the test is much shorter than that. The official site says there are time limits on each subtest but almost all examinees finish before time expires, and that the proctored CAT-ASVAB takes about 2 hours on average. The test is self-paced: when you finish a subtest you go straight on to the next one, without waiting for the rest of the room. The time and number of questions left in the current subtest are shown in the lower right-hand corner of the screen.

Tryout questions: why your count may differ from a friend's

Tryout questions are new questions being tested for future use. They do not count toward your score. Each examinee gets them in 2 to 4 subtests, with the tryout questions randomly dispersed among the scored questions of each selected subtest. When a subtest includes tryouts, its time limit is extended to the "with tryouts" column above.

That is why two people who took the CAT-ASVAB on the same day can remember different numbers of questions: one may have had tryouts in Arithmetic Reasoning (up to 30 questions and 113 minutes), the other in Word Knowledge. Treat every question as if it counts.

Paper-and-pencil ASVAB: questions and time per subtest

On paper, every examinee gets the same fixed set of questions, including very easy and very hard ones (The CAT-ASVAB). Auto and Shop Information are combined into one subtest.

The 149 minutes are testing time only. With check-in, instructions and handing out booklets, the official site puts the whole session at 3 to 4 hours. Unlike the computer version, you can review your answers within a subtest, but you cannot go back to an earlier subtest or move on until the administrator says so. Answer sheets are then scanned at the MEPS, which usually takes a few days.

The per-question column shows where the pressure is: Word Knowledge and General Science move fast, while Arithmetic Reasoning gives you more than a minute per problem.

PiCAT and APT: the online versions

PiCAT is the unproctored online CAT-ASVAB taken at home with an access code from a recruiter. According to What to Expect, it has no time limits on individual subtests and no tryout questions, and it takes around 2 to 3 hours. The code expires 30 days after it is issued, and once you start you must finish within 48 hours. It can be taken only once, and only if you have never taken the ASVAB. If your scores suggest you may be eligible, you take a proctored Verification Test at a MEPS or MET site within 45 days; it generally takes 25 to 30 minutes.

APT, the AFQT Predictor Test, is not the ASVAB. It is a short adaptive screening test on the four AFQT subtests only (Arithmetic Reasoning, Math Knowledge, Word Knowledge, Paragraph Comprehension), with 20 items in total, no time limits, and a typical length of 20 to 30 minutes. Only the recruiter sees the score.

Does the number of questions change your score?

No. A shorter adaptive test is not easier or harder in the end: the official FAQs say that scores on the computer and paper versions are statistically linked, so you would be expected to get a similar score either way. What changes is strategy, according to Preparing for the ASVAB:

• Computer: you cannot go back once you answer, and the CAT-ASVAB applies a relatively large penalty when several incorrect answers are given toward the end of a subtest, so if time runs short, read and answer the remaining questions properly rather than filling in random guesses.
• Paper: there is no penalty for guessing, so fill in every answer before time is called.

How the answers turn into an AFQT percentile and line scores is covered in our ASVAB scores guide, and a study plan by subtest is in our ASVAB study guide. To practise the timing, our free ASVAB practice test and its subtest pages (Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension, Math Knowledge) use original questions with an explanation for every answer.
