At a Military Entrance Processing Station (MEPS), you complete the three things that turn an applicant into a service member: a full medical examination, the ASVAB aptitude test (or verification of a score you already earned), and enlistment paperwork that ends with the oath of enlistment. Most people finish in one to two days. Expect a lot of waiting between stations, an early start, and a structured sequence you move through with other applicants.
The Night Before and Checking In
If you live far from your MEPS, your recruiter arranges a hotel room the night before at military expense. You’ll get a short orientation, an early wake-up (processing days typically start around 5:00 or 6:00 a.m.), and breakfast before you begin.
Bring a government-issued photo ID, your Social Security card, and any medical documentation your recruiter asked you to gather. Bring glasses or contacts if you wear them. Dress comfortably and modestly, and wear sneakers.
Security at the door works like an airport screening: bag check and metal detector. Leave the following at home or in your hotel room:
- Weapons or ammunition of any kind, including pocket knives.
- Drugs, alcohol, or drug paraphernalia.
- Outside food and drinks (meals are provided).
- Tobacco and e-cigarettes.
Phones and cameras are generally allowed in the building, but photos and video are only permitted in the oath ceremony room. After security, you’ll be fingerprinted for a background check and complete initial paperwork.
The Medical Examination
The medical exam takes up most of your MEPS day. Its purpose is to determine whether you meet the Department of Defense’s medical accession standards.
Vision, Hearing, and Vitals
You’ll rotate through stations for distance and color vision, a hearing test in a soundproof booth, and measurement of your height, weight, blood pressure, and pulse. If your weight falls outside the acceptable range for your height and branch, you may be temporarily disqualified until you meet the standard.
Blood, Urine, and Drug Testing
Every applicant gives a blood sample and a urine sample. Blood is tested for HIV. Urine is screened for drugs and alcohol, and female applicants are given a pregnancy test from the same sample. A breath alcohol test is also administered.1Headquarters, United States Military Entrance Processing Command. USMEPCOM Regulation No 40-8 – DoD HIV Testing Program and Drug and Alcohol Testing Program A positive drug test is an immediate disqualifier. Depending on the branch, you may be able to reapply after a waiting period.
The Physical Exam
A MEPS physician does a hands-on examination covering your body systems, including neurological and musculoskeletal checks. You’ll also perform a set of movements designed to reveal joint, muscle, or skeletal problems. The best-known is the “duck walk,” where you move forward in a deep squat, rolling each foot heel-to-toe without standing up. It screens for flat feet, weak arches, hip problems, and balance issues. Other exercises test range of motion in your shoulders, knees, and spine. These are done individually, not in a group.2U.S. Army. Processing and Screening MEPS
Medical History
You’ll complete a medical history questionnaire and review it with the MEPS doctor. Be honest. The Department of Defense now uses MHS GENESIS, connected to the Joint Health Information Exchange, which can pull civilian medical records from hundreds of participating health networks, including large systems like Kaiser Permanente, Cleveland Clinic, Mayo Clinic, Johns Hopkins, and many state health information exchanges.3Health.mil.

My Military Health Records MEPS also encourages you to bring documentation from your personal physicians, because those records feed directly into your qualification decision.1Headquarters, United States Military Entrance Processing Command.

If You’re Medically Disqualified
If the MEPS physician flags a condition that doesn’t meet accession standards, you’ll receive a temporary or permanent disqualification. Many conditions are waiverable, meaning your branch can approve an exception if the condition doesn’t genuinely prevent service. The DoD splits disqualifying conditions into two groups: those that require a medical accession waiver approved by the Secretary of the relevant military department (including serious conditions such as a history of heart attack, absence of a hand or foot, or disorders with psychotic features), and a second group that is ineligible for any waiver and permanently bars service.5Secretary of Defense. Medical Conditions Disqualifying for Accession Into the Military
Waivers start with your recruiter, who submits the request up the chain. The process can take weeks or months, and approval is never guaranteed. If you know about a potentially disqualifying condition, gathering thorough documentation from your doctor before your MEPS visit can move things along.
The ASVAB
The Armed Services Vocational Aptitude Battery is a timed test covering math, reading comprehension, science, electronics, and mechanical reasoning. Your composite AFQT (Armed Forces Qualification Test) score determines whether you can enlist at all. Line scores from individual subtests determine which jobs you qualify for within your branch.
If you haven’t already taken the ASVAB at a school or recruiting office, you’ll take the computerized version at MEPS. If you took the PiCAT, an unsupervised version done on your own time, you’ll complete a shorter verification test at MEPS to confirm your score.6U.S. Army. ASVAB Test and Preparation
Minimum AFQT scores vary by branch and shift with recruiting needs, so confirm current cutoffs with your recruiter. If your score isn’t high enough, retest rules apply: one calendar month before your first retest, another month before the second, and six months between attempts from the third retest on.7Headquarters, United States Military Entrance Processing Command. USMEPCOM Regulation No 611-1 – ASVAB Testing Program Study before your first attempt rather than counting on a retest.
Meeting Your Career Counselor
Once your medical results and ASVAB scores are in, you sit down with a military career counselor (sometimes called a guidance counselor). The counselor reviews your AFQT and line scores, cross-references them with jobs currently available in your branch, and walks you through what each one involves.2U.S. Army. Processing and Screening MEPS
Availability depends on more than test scores. Medical qualifications, security clearance eligibility, and current manning needs all factor in. A job being “available” means there’s an actual slot open right now. If nothing appeals to you during this session, you’re not obligated to pick a job on the spot; you can talk it over with your recruiter and return later, though this extends your timeline.
The Pre-Enlistment Interview and Signing the Contract
Before you sign anything, a MEPS official conducts a Pre-Enlistment Interview (PEI). The questions cover criminal history, drug use, and other eligibility issues, serving as a final screening layer separate from the medical exam. Honesty matters here for the same reasons it matters on the medical forms.2U.S. Army. Processing and Screening MEPS
After clearing the PEI, you and your guidance counselor review the enlistment contract, officially DD Form 4. It spells out your chosen job, length of service, branch, and any bonuses or special incentives. Read every line. If anything doesn’t match what your recruiter told you, stop and ask questions. Once the oath is administered and the contract is signed by the enlisting officer, it becomes legally binding.8Department of Defense. DoD Manual 1145.02 – Military Entrance Processing Station MEPS
The Oath of Enlistment
The last step at MEPS is the oath ceremony. A commissioned officer administers it in a formal ceremony, usually in a dedicated room where family members are welcome to watch and take photos. You raise your right hand and swear (or affirm) to support and defend the Constitution of the United States against all enemies, to bear true faith and allegiance, and to obey the orders of the President and the officers appointed over you, according to regulations and the Uniform Code of Military Justice.9Office of the Law Revision Counsel. 10 USC 502 – Enlistment Oath Who May Administer
After the oath, the enlisting officer signs your DD Form 4 and you are officially a member of the U.S. military.8Department of Defense. DoD Manual 1145.02 – Military Entrance Processing Station MEPS For most enlistees, that doesn’t mean shipping out tomorrow.
After MEPS: DEP or Ship Day
Most new enlistees enter the Delayed Entry Program (DEP), which lets you finish school, get personal matters in order, or wait for your job’s training pipeline to open. Federal law allows you to remain in the DEP for up to 365 days, and the Secretary of your branch can extend that by an additional 365 days if needed.10Office of the Law Revision Counsel. 10 USC 513 – Enlistments Delayed Entry Program
During the DEP, your recruiter stays in contact, often scheduling meetings and physical fitness sessions. You’ll be given personal conduct rules and expected to stay out of legal trouble and keep up your fitness.2U.S. Army. Processing and Screening MEPS A DEP agreement is a statement of intention to report for formal enlistment; it does not bind you to active duty, and you can request separation in writing if you change your mind. Walking away can complicate any future attempt to enlist, so treat the decision seriously.
When your ship date arrives, you return to MEPS one more time. The night before follows the same routine: hotel, early wake-up, breakfast. At MEPS, you’ll get a briefing on travel procedures, a quick medical screening to confirm nothing has changed since your initial exam, final paperwork, and the oath of enlistment a second time. That second oath is the one that formally brings you onto active duty. From there, you receive travel documents and head to the airport or bus station for transportation to basic training.
