MEPS (Military Entrance Processing Stations) is a Department of Defense facility where all prospective military members complete medical examinations, aptitude testing, and enlistment processing. There are 65 MEPS locations across the United States, and every person who joins the Army, Navy, Air Force, Marines, Coast Guard, or Space Force must process through one.

Candidates can also sharpen their skills with our ASVAB practice test 2026, which includes hundreds of practice questions in the exact format and difficulty of the real exam.

What Is MEPS and Why Does It Matter?

The Military Entrance Processing Station is the gateway between civilian life and military service. No matter which branch you are joining, MEPS is where the Department of Defense determines whether you are physically, mentally, and morally qualified to serve.

MEPS serves three core functions:

• Aptitude testing — The Armed Services Vocational Aptitude Battery (ASVAB) measures your abilities across ten subtests, producing line scores that determine which Military Occupational Specialties (MOS) or ratings you qualify for.
• Medical screening — Military physicians evaluate your physical health against Department of Defense standards outlined in DoDI 6130.03. Conditions that are manageable in civilian life may be disqualifying for military service.
• Enlistment processing — After clearing medical and aptitude requirements, you meet with a service liaison counselor to select your job, review your contract, and take the Oath of Enlistment.

Your recruiter will schedule your MEPS visit and handle transportation logistics. Most applicants either drive to MEPS early in the morning or stay at a nearby hotel the night before if the station is far from their home. The government covers hotel and meal costs.

Prepare for the aptitude testing portion by practicing with MEPS Applicant Processing and Standards Questions and Answers to familiarize yourself with the standards that MEPS evaluates.

Day One: ASVAB Testing and Arrival

Your MEPS experience typically begins with the ASVAB, either taken at MEPS itself or at a satellite testing location called a Military Entrance Test (MET) site. If you take the ASVAB at a MET site beforehand, your first day at MEPS will focus entirely on medical processing.

ASVAB at MEPS:

The computerized version (CAT-ASVAB) takes approximately 1.5 to 2 hours. You answer questions in ten subtests:

• General Science (GS) — Life science, earth science, physical science
• Arithmetic Reasoning (AR) — Word problems requiring math skills
• Word Knowledge (WK) — Vocabulary and word meaning
• Paragraph Comprehension (PC) — Reading comprehension passages
• Mathematics Knowledge (MK) — Algebra, geometry concepts
• Electronics Information (EI) — Basic electrical principles
• Auto and Shop Information (AS) — Vehicle and workshop knowledge
• Mechanical Comprehension (MC) — Mechanical principles and physics
• Assembling Objects (AO) — Spatial reasoning puzzles
• Verbal Expression (VE) — Combined WK and PC score

Your AFQT score (Armed Forces Qualification Test) is calculated from Arithmetic Reasoning, Mathematics Knowledge, Word Knowledge, and Paragraph Comprehension. You need a minimum AFQT of 31 for the Army, 32 for the Marines, 36 for the Navy, and 36 for the Air Force, though higher scores open significantly more career options.

What to bring to MEPS:

• Valid government-issued photo ID (driver's license or passport)
• Social Security card
• Birth certificate
• Any medical records your recruiter requested
• Eyeglasses or contact lenses if you wear them (bring both)
• Comfortable clothing — you will be doing physical movements during the medical exam

What NOT to bring: Weapons, drugs, alcohol, electronics (phones must stay in a locker), excessive jewelry, or clothing with offensive graphics.

The MEPS Medical Examination

The MEPS medical exam is the most thorough part of the process and the step that disqualifies the most applicants. Military physicians follow strict Department of Defense standards, and the exam covers every major body system.

What the medical exam includes:

1. Height and weight — You must meet your branch's body composition standards. If you exceed weight limits, a body fat measurement (tape test) is performed.
2. Vision test — Distance vision, near vision, color vision, and depth perception. Color blindness disqualifies you from certain jobs but not from service entirely.
3. Hearing test — Audiometric testing in a soundproof booth across multiple frequencies.
4. Blood draw — Tests for HIV, sickle cell trait, blood type, and other conditions.
5. Urinalysis — Drug screening and basic metabolic panel. Any positive result for illegal substances is an immediate disqualification.
6. Breathalyzer — Alcohol screening. Do not drink the night before MEPS.
7. Orthopedic evaluation — The "duck walk," range of motion tests, joint flexibility, and checks for scoliosis, flat feet, or prior surgical scars.
8. Full physical exam — A physician examines your heart, lungs, abdomen, skin, and neurological function. You will be in your underwear for portions of this exam.
9. Medical history review — A doctor reviews your pre-screening questionnaire and asks follow-up questions about any conditions, surgeries, medications, or hospitalizations.

The medical exam typically takes 4 to 6 hours. You move through stations in groups, and there is significant waiting time between each step. Bring patience — rushing is not an option at MEPS.

Job Counseling and MOS Selection

Once you clear the medical exam and have qualifying ASVAB scores, you move to the job counseling phase. This is where your military career truly takes shape.

A service liaison counselor from your chosen branch sits down with you and reviews:

• Your ASVAB line scores — Different jobs require different composite scores. A high General Technical (GT) score of 110+ opens intelligence and technical fields. A strong Clerical (CL) score qualifies you for administrative and finance roles.
• Available jobs — The counselor shows you which MOS, rating, or AFSC positions are currently available based on your scores, medical qualifications, and the branch's needs.
• Enlistment incentives — Bonuses, guaranteed training dates, and education benefits may be tied to specific job selections.
• Contract length — Most initial enlistment contracts are 4 or 6 years of active duty, though some jobs require longer commitments.

Tips for job selection:

1. Research beforehand. Know your top 5 job choices before arriving at MEPS. Your recruiter should have already discussed options based on your practice ASVAB scores.
2. Do not settle. If your preferred job is not available, you can usually wait and come back when it opens up. You are not obligated to sign a contract on the spot.
3. Consider civilian transferability. Jobs in IT, medical, aviation maintenance, and intelligence translate well to civilian careers after service.
4. Read every word of your contract. Verify the job title, ship date, bonus amounts, and any special provisions before signing.

After agreeing to a contract, you take the Oath of Enlistment. This is a formal ceremony where you swear to support and defend the Constitution. Family members are often allowed to attend.
