Frequently Asked Questions
What is the CAT-ASVAB?
The CAT-ASVAB is the Computer Adaptive Test version of the ASVAB administered at MEPS. It serves 145 questions across 10 subtests in approximately 1.5-2 hours. Each subtest is adaptive: harder questions follow correct answers and easier questions follow incorrect ones, so test length is shorter than the paper version while measuring the same constructs.
How is CAT-ASVAB different from paper ASVAB?
The CAT-ASVAB has 145 questions and adapts difficulty in real time, while the paper-and-pencil ASVAB (P&P-ASVAB) has 225 fixed questions. CAT-ASVAB also splits Auto Information (AI) and Shop Information (SI) into separate subtests, whereas the paper version combines them into a single Auto & Shop section. Both produce equivalent AFQT scores.
What AFQT score do I need on the CAT-ASVAB?
Minimum AFQT scores by branch: Army 31, Marines 31, Navy 31, Air Force 36, Space Force 36, Coast Guard 40. Higher scores qualify you for more jobs — AFQT 50+ opens most career fields. The AFQT is calculated from four subtests: WK + PC + AR + MK.
Can I skip questions or go back on the CAT-ASVAB?
No. Because the CAT-ASVAB adapts to your responses, you cannot skip a question or return to a previous item once you submit. Answer carefully — guessing late in a subtest can be penalized if you run out of time without completing items.
Where is the CAT-ASVAB administered?
The CAT-ASVAB is delivered at Military Entrance Processing Stations (MEPS) on DoD-managed computers. The paper P&P-ASVAB is used at Mobile Examining Test (MET) sites for applicants who cannot travel to a MEPS facility.
