Joining the military: Steps for every branch

Within the U.S. military, aspiring recruits have a wide range of paths to choose from. Early in the enlistment process, every candidate completes a common step: taking the Armed Services Vocational Aptitude Battery (ASVAB). This is the primary assessment each branch uses to measure eligibility and identify suitable military career opportunities. While the ASVAB is used across all branches, the minimum required scores and standards differ depending on whether you’re pursuing a role in the Coast Guard, Air Force, Marines, or Army. Each service sets its own qualifying scores for both entry-level and specialized positions.

In addition to achieving qualifying ASVAB results, those interested in joining the Armed Forces must also meet several other military requirements before officially enlisting. Though most branches accept both U.S. citizens and lawful permanent residents (the Space Force takes U.S. citizens only), and all require proof of physical and mental fitness, the criteria for age, testing, and job qualifications differ among the services. Reviewing these prerequisites early in your application process can help ensure you meet all standard requirements and make a plan to reach your target ASVAB score for your chosen branch.

Keep in mind that the guidelines below apply to enlisted personnel; requirements for commissioned officers are different and may include a college degree, younger age cut-offs (the Army, for example, takes enlisted soldiers up to age 42 but requires officers to commission before 31), and officer tests in place of the ASVAB.

A note on ASVAB subtests

The ASVAB is the assessment tool used across all U.S. military branches for determining enlistment eligibility and career placement. The core structure and content of the ASVAB remain consistent among all branches. This wide-ranging, multiple-choice examination is divided into 10 subtests:

• General Science (GS): Measures foundational knowledge in physical and biological sciences, including topics in biology, chemistry, physics, and earth science.
• Arithmetic Reasoning (AR): Evaluates the ability to solve arithmetic word problems by applying mathematical concepts and logical reasoning.
• Word Knowledge (WK): Tests vocabulary skills through synonym recognition and understanding word meanings.
• Paragraph Comprehension (PC): Assesses reading comprehension by interpreting short passages and identifying main ideas and specific details.
• Mathematics Knowledge (MK): Focuses on high school math principles, such as algebra, geometry, and commonly used formulas.
• Electronics Information (EI): Gauges understanding of fundamental electrical concepts, circuits, currents, voltage, and general electronics knowledge.
• Auto Information (AI): Reviews concepts related to automobile systems, maintenance practices, tool identification, and basic automotive technology.
• Shop Information (SI): Tests familiarity with workshop tools, materials, and everyday shop procedures commonly encountered in mechanical environments.
• Mechanical Comprehension (MC): Measures grasp of mechanical principles such as gears, pulleys, levers, and the basics of mechanical motion.
• Assembling Objects (AO): Examines spatial awareness and reasoning skills by determining how various components fit together to make complete objects.

Your scores also produce Verbal Expression (VE), which isn’t a subtest: it’s a weighted combination of Word Knowledge and Paragraph Comprehension, used in the AFQT and in many line scores. For those taking the paper-based ASVAB format (as opposed to the computerized version), it is important to note that Auto Information and Shop Information are combined into a single subtest, resulting in a total of nine scored batteries. Regardless of the branch you choose, these ASVAB subtests are combined to evaluate your qualifications for specific military occupational specialties and to determine enlistment eligibility benchmarks.

This uniformity ensures that whether you’re considering service in the Army, Navy, Air Force, Marine Corps, or Coast Guard, the ASVAB provides a standardized measure of aptitude used universally across military branches.

ASVAB AFQT

One of the most important composite scores on the ASVAB is the Armed Forces Qualification Test (AFQT). The AFQT score is calculated from the Arithmetic Reasoning and Math Knowledge subtests as well as the Verbal Expression composite measure, yielding a percentile ranking that helps set cut-off points for military enlistment eligibility. Each military branch sets its own minimum AFQT score for enlistment, listed in the sections below and compared side by side in What ASVAB score do you need?

Note that the AFQT numbers featured apply to candidates with high school diplomas. Those with GEDs typically need a score of 50 or higher to qualify for the armed forces.

Requirements to join the U.S. Army

Minimum AFQT score for the Army: 31

To qualify for the Army, you must meet these standards:

• Age: Be between 17 and 42 years old
• Citizenship: Be a U.S. citizen or a permanent resident with a valid Green Card
• Education: Possess a high school diploma or have an approved equivalent, such as a GED
• Physical fitness: Meet Army medical and physical standards
• Background: Pass a thorough criminal background check

The ASVAB scores for Army enlistment determine eligibility and qualification for various military occupational specialties (MOSes). Each specialized job has unique ASVAB line score requirements, which depend on specific combinations of ASVAB subtests.

The key Army line scores and their calculations include:

• Clerical (CL): VE + AR + MK
• Combat (CO): VE + AS + MC
• Electronics (EL): GS + AR + MK + EI
• Field Artillery (FA): AR + MK + MC
• General Maintenance (GM): GS + AS + MK + EI
• General Technical (GT): VE + AR
• Mechanical Maintenance (MM): AS + MC + EI
• Operators and Food (OF): VE + AS + MC
• Surveillance and Communications (SC): VE + AR + AS + MC
• Skilled Technical (ST): GS + VE + MC + MK

Each Army job sets its own line-score minimums, and specialized careers generally ask for higher line scores than entry-level ones; a recruiter can confirm the current cutoff for a specific job. Earning competitive ASVAB scores for Army enlistment goes beyond meeting the initial eligibility requirements and opens doors to a broader range of military job options.

Requirements to join the U.S. Navy

Minimum AFQT score for the Navy: 31, according to Navy recruiting policy (50 with a GED)

In addition to the Navy ASVAB score requirement, you must meet the following eligibility standards:

Your Navy ASVAB score is critical not only for enlistment but also in qualifying for specific Navy ratings. Unlike other branches, the Navy determines job eligibility using subtest minimums related to each role rather than fixed line scores.

Here are some minimum ASVAB line scores for select Navy jobs, according to Operation Military Kids (navy.com’s job pages don’t list them):

• Aviation Boatswain’s Mate: VE + AR + MK + AS = 173
• Electronics Technician (Nuclear): AR + MK + EI + GS = 252 or VE + AR + MK + MC = 252
• Intelligence Specialist: VE + AR + MK + GS = 215
• Culinary Specialist: VE + AR = 82

Score requirements for particular ratings can change periodically. For the most accurate and up-to-date information on score expectations and career opportunities, consult with a Navy recruiter. Staying informed on current standards ensures you are properly prepared to meet all Navy enlistment criteria.

Requirements to join the U.S. Marine Corps

Minimum AFQT score for the Marines: 31 (50 with a GED)

Because of the advanced technology and complexity of its roles, each Space Force job sets its own minimum composite score, from a General score of 46 to 72 among the jobs above. Candidates seeking to join should ensure they meet or exceed the required Space Force ASVAB score for their desired position, as these benchmarks reflect the branch’s specialized, technical mission focus.

Additional questions

Is the ASVAB the same for all branches?

Yes, a single ASVAB is administered to all recruits, though score standards differ by branch.

What branch has the lowest ASVAB score?

For applicants with a high school diploma, the Army, Navy, Marine Corps, and Air Force set the minimum AFQT at 31, and the Coast Guard at 32. The Space Force doesn’t publish a minimum; confirm it with a recruiter. Keep in mind that elite roles in all branches require high individual subtest scores.

What if my ASVAB score is too low?

If you don’t meet the AFQT requirement for a specific branch, you will not be able to enlist. However, you can retake the test, and there’s no lifetime limit on how many times you can take the ASVAB. You must wait one calendar month after your first test, another calendar month after your first retest, and six calendar months between retests after that.

In special circumstances, enlistees may request a waiver if their scores do not automatically qualify them for service; the Army, for example, says a waiver can be requested when circumstances affected your score. In most cases, retaking the test is a better option.

How can I achieve my desired position in the military?

Start by exploring the range of military jobs available to enlisted members. The military offers a wide variety of roles, including technical and mechanical positions, surveillance and intelligence work, and public relations positions. Think about your skills and interests, then create a list of positions that appeal to you. Afterward, research the ASVAB line score requirements for those jobs and focus your study plan on the specific subtests needed to qualify. A free ASVAB practice exam can show you which of those subtests need the most work.

Keep in mind that enlisting is only one path in the military. Those who want to serve as commissioned officers should look into other options, such as attending a military academy, enrolling in college and joining an ROTC program, or completing officer training school (ideal for those who have already graduated from college). While enlistment generally requires a high school diploma, officer positions usually require at least a bachelor’s degree.

Where can I learn more about ASVAB requirements?

The best way to understand ASVAB requirements for each military branch is to speak directly with a recruiter from the branch you’re interested in. A recruiter can answer your questions, help clarify your career goals, and guide you through the process of registering for the ASVAB.

Final takeaways

While each branch of the military uses a unique approach to recruiting and onboarding, one component remains consistent: strong ASVAB performance. Your first milestone is achieving the minimum Armed Forces Qualification Test (AFQT) score benchmark. Typically, an AFQT score of 31 or higher is required to get started, though some branches, roles, and programs may demand higher numbers. Earning this baseline opens the door, but the opportunity to pursue in-demand specialties depends on your results from the various subtests.

It’s important to understand that while there are common enlistment requirements overall, the ASVAB scores for each branch differ when it comes to specific job placement and advancement opportunities. Tailoring your ASVAB preparation strategy not only to your branch of choice but also to your desired military career path, whether it’s leading technology initiatives in Army cyber operations or qualifying as an Air Force mechanic, ensures that you’re focusing on the areas most critical for success. Achieving a higher score can expand your options for specialized and higher-paying roles. By taking an informed approach to your preparation and knowing the role ASVAB results play in your chosen path, you can work toward the scores you need to secure your ideal job in any branch of service.
