The Armed Services Vocational Aptitude Battery (ASVAB) comes in four versions, depending on where and why you take it. The following table boils down the choices.
For people taking the enlistment version of the test, the vast majority of applicants are processed through a MEPS, where they take the computerized format of the ASVAB (called the CAT-ASVAB, short for computerized-adaptive testing ASVAB), undergo a medical physical, and run through a security screening, many times all in one trip. The paper-and-pencil (P&P) version is most often given in high school and, rarely, at Mobile Examination Test (MET) sites located throughout the United States. Most MET sites use computers to administer the test.
