Three Versions of the ASVAB
 |
|
The Armed Services Vocational Aptitude Battery serves many purposes and comes in three forms; each is targeted to different needs. In addition each ASVAB has different benefits and limitations. The ASVAB versions are:
The CAT-ASVAB A large number of potential military recruits take the CAT-ASVAB. This computer adaptive test is an automated test administration system that displays questions, scores and records answers, scores ASVAB subtests, computes your AFQT, and allows for flexible start times and self-paced responses. This test is given at a Military Entrance Processing Station (MEPS) and is used for enlistment purposes only.
The CAT takes about an hour and a half. The exam covers the same sub-tests as the MET-site ASVAB, except the CAT has 10 sub-tests because it divides the Auto Shop subtest into 2 subtests – Auto Information and Shop Information.
Computerized Adaptive Testing means that if the correct answer is chosen, the next question will be harder. If the answer given is incorrect, the next question will be easier. This also means that once an answer is selected on the CAT it cannot be changed.
Although you can speed through the CAT at your own pace, the test does have a time limit. If you finish a subtest before the time limit is reached, you automatically go on to the next test. Unlike the MET-site ASVAB you may leave the test room as soon as you are finished.
Note: Prospective Navy recruits also take the Coding Speed (CS) test. This test is used to be one of the ASVAB subtests. CS is now a special test used only by the Navy for classification into some Navy specialties.
Scoring the CAT-ASVAB
Your CAT-ASVAB subtest scores are computed using formulas that take into account the difficulty of the test question and correctness of the answer. Your CAT-ASVAB raw scores are not equal to the total number of correct answers. Test scores are good for two years.

The MET-site ASVAB is given at a Mobile Examination Test site. This test is used solely for enlistment into one of the military services. Test sites are located in different cities. You will need to be referred by a recruiter to take the MET-site ASVAB.
The MET is a three and a half hour, nine test multiple-choice exam where you write your answer on a separate answer sheet. Since it is a pen and paper test, answers can be changed. But be sure to completely erase all the changes you make – the answer sheet scanner is very sensitive. You are given a set amount of time, so you must do your best to answer all the questions in the time given. Unlike the CAT-ASVAB, you may not leave the testing room if you finish before the other testers.
TIP: GUESS - Your test score is based on the number of items you have answered correctly in the allotted time, you are not penalized for wrong answers. That’s why you should guess if you do not know the answer or if you start to run out of time.
Scoring the MET-site ASVAB
The test administrator sends test results back to the MEPS. The MEPS test administrator will give you a sealed envelope, which contains your unverified test scores to take back to your recruiter. Once your answer sheet has been scored at the MEPS, you will be able to get your verified test scores from your recruiter.

The Student ASVAB is used for career exploration for high school and college students. This pen and paper test version is given in high schools, colleges, or vocational schools. It is approximately 3 hours and is composed of 8 subtests.
Test results are sent to your school for you and your counselor to explore careers (this is called a post-test interpretation). You will also be given an interest inventory (Find Your Interests). Your ASVAB test results and “Find Your Interests” are tools for you to explore different occupations, identify a college major, and find out about your personality. Your AFQT military qualification score is reflected on your test results and can be used to enlist in any of the military services.
