Minimum AFQT Score Requirements
To join any branch of the military, applicants must have a high school diploma or a high school equivalency degree (e.g., GED). While your recruiter will have the most up-to-date information, here are the current minimum ASVAB requirements for each branch of the military, excluding the Space Force:
Frequently Asked Questions
The Armed Services Vocational Aptitude Battery
The Armed Services Vocational Aptitude Battery (ASVAB) is used by the Department of Defense to determine if an individual is eligible to enlist in any branch of the United States Armed Forces. More specifically, scores from four of its subtests—the Word Knowledge, Paragraph Comprehension, Mathematics Knowledge, and Arithmetic Reasoning subtests in particular—are used to compute an Armed Forces Qualification Test (AFQT) score for everyone who takes it. While the test cannot be failed per se, each branch of the military has established minimum AFQT score requirements for candidates to be eligible for enlistment. For example, the Army requires candidates who have at least a high school diploma to obtain a minimum AFQT score of 31 to eligible for enlistment. In addition, AFQT scores are used to group recruits into different categories. For instance, candidates who obtain AFQT scores between 93 and 99 are considered Category I recruits and are regarded as highly trainable, whereas candidates who obtain AFQT scores of 9 or lower are considered Category V recruits. These recruits are prohibited by law from enlisting in the military.
How long is the ASVAB?
It depends on which version you take. More often than not, you’ll take the computer-adaptive version of the ASVAB at a Military Entrance Processing Station (MEPS), and it takes approximately three hours and twenty minutes to complete. The CAT-ASVAB consists of the following subtests, number of questions, and time limits:
|General Science (GS)||16||8|
|Arithmetic Reasoning (AR)||16||39|
|Word Knowledge (WK)||16||8|
|Paragraph Comprehension (PC)||11||22|
|Mathematics Knowledge (MK)||16||20|
|Electronics Information (EI)||16||8|
|Auto Information (AI)||11||7|
|Shop Information (SI)||11||6|
|Mechanical Comprehension (MC)||16||20|
|Assembling Objects (AO)||16||16|
When and how can I take the ASVAB?
In general, the ASVAB is offered year-round. If you’re still in high school, you can contact your school’s guidance counselor, and he or she will help you register for an ASVAB test that will likely be given at your school. Otherwise, you can contact your local military recruiter, and if you’re eligible, they should initiate the process for you.
Am I ready to take the ASVAB?
Thankfully, prior to sending you to a Military Entrance Processing Station (MEPS) to take the CAT-ASVAB, your local recruiter will likely give you a pre-screening, internet-delivered Computer Adaptive Test (PiCAT) in his or her office. The PiCAT is an unproctored version of the ASVAB, and recruiters use it to determine if you’re ready for the real test.
How many times can I take the ASVAB?
It depends, since ASVAB scores are valid for two years from the date you take the test. In light of that, the following restrictions apply:
- After each attempt on the ASVAB, you must wait at least 30 days before you can take it again; and
- After your third attempt, you will be required to wait six months between each attempt.
Your recruiter will have the most up-to-date information about this, insofar as the military sometimes changes its policy regarding this.
I’m not good at math. What should I study to pass the ASVAB?
Again, the ASVAB has two different math subtests, notably the Arithmetic Reasoning and Mathematics Knowledge subtests.
Generally, the Arithmetic Reasoning subtest includes the following topics:
- absolute value
- prime numbers
- multiplication and long division, including with fractions and decimals
- exponents, radicals, scientific notation
- order of operations
- ratio, proportion, and rates
- mean, median, mode
- word problems involving distance, rate, and time, combined work, ratio and proportion, and percent increase or decrease
Generally, the Mathematics Knowledge subtest includes the following topics:
- solving systems of equations
- lines and angles (e.g., right, acute, obtuse, vertical, and supplementary)
- triangles, quadrilaterals, and circles
- area, perimeter, and similarity
- solid geometry: surface area and volume
- coordinate geometry (e.g., linear equations, slope, slope-intercept form, and distance between points)
What resources do you recommend to study for the ASVAB?
Not surprisingly, I would recommend Grammar Hero’s YouTube Channel. There, you’ll find videos for just about every topic that’ll show up on the ASVAB. Apart from that, I would recommend checking out a copy of ASVAB for Dummies or a similar study guide from your local library. In light of the fact a lot of people are turned away from military service due to underlying medical conditions, I would not recommend buying any test prep materials or paying for tutoring.
What is an AFQT score?
As mentioned above, AFQT stands for Armed Forces Qualification Test, and it computed by averaging your scores on the Word Knowledge, Paragraph Comprehension, Mathematics Knowledge, and Arithmetic Reasoning subtests. In short, your AFQT score is used by each branch of the military to determine if you are eligible for enlistment. Beyond that, it is what the military uses to gauge your level of trainability. The higher your AFQT score is, the easier you should be able to train to complete complex tasks. AFQT scores are ranked in the following categories:
|Category III A||50–64|
|Category III B||31–49|
|Category IV A||21–30|
|Category IV B||16–20|
|Category IV C||10–15|
What are the minimum AFQT score requirements?
Air Force – To join the Air Force, you need minimum AFQT score of 36. If you have a high school equivalency degree but have not completed at least 15 hours college credit, you need a minimum ASVAB score of 65. Of all the branches, the Air Force is the most selective.
Army – To join the Army, you need a minimum AFQT score of 31. If you have a high school equivalency degree , you need a minimum AFQT score of 50.
Coast Guard – To join the Coast Guard, you need a minimum AFQT score of 40. Those with only a high school equivalency degree need a minimum AFQT score of at least 50 and, in addition, should have at least 15 hours of college credit.
Marine Corps – To join the Marine Corps, you need a minimum AFQT score of 32. If you have a high school equivalency degree, you need a minimum AFQT score of 50.
Navy – To join the Navy, you need a minimum AFQT score of 35. Those with only a high school equivalency degree need a minimum AFQT score of at least 50 and, in addition, should have at least 15 hours of college credit.
What jobs did I qualify for?
Since the military offers hundreds of different career paths, it would be nearly impossible to give you a concise answer. Assuming you already took the ASVAB and saved the printout of your line scores, you can use the following resources to determine what military occupational specialties you qualify for:
In addition, your recruiter will give you more information about potential career paths. However, I strongly encourage you to spend some time researching different military careers before you take your physical at MEPs. In doing so, you will have an idea as to what you’re willing to do with the next four to six years of your life.
I have additional questions. Who can I ask?
Ask a recruiter, a family member, a military veteran, or a smart friend!
Thank you! Went from a 17 to a 44 just watching your videos! Not the best but its decent!
Just took my asvab yesterday. With your videos alone I went from a 7 to getting a 52 on my ASVAB🙏 thanks a lot man you’re really blessing people.
Thanks for making these videos. I took my asvab a week ago and I got a 77 on it.
Israel Akande Grammar Hero The first time I took the asvab I got a 37. I studied agin and I got 51 . But the study plan on your website was a big player in my score of 77
You’re study guide helped me Soo much. THANK YOU!!! first practice test I received a 38. For my ASVAB I received an 82!!! Thanks again, you’re way helped me understand the material so much better than any book I’ve gotten 🙏🏽💪🏽
Your videos really helped me improve my AFQT Score. Went from 26 to 53. Now MEPS is scheduling me for a confirmation test. Should I study for it still??
Hey I also took the ASVAB I scored a 74 from a 19. Honestly for whoever is reading this and plan on taking the ASVAB I highly recommend this channel. Trust me what I saw on there was topics that this channel covered. Also this doesn’t mean I’m done watching your channel. I’ll still be sticking around showing support because honestly if it wasn’t for you I wouldn’t be heading where I’m heading now. This channel is underrated. I’ll try my best to help put your channel out there, really appreciate it man much love.
I think it will be an act of ingrate if I don’t come back here to say big thanks to you. I took my test today and my score increased from 22 to 60. Thank you so much
Watched your videos everyday! Took my asvab at MEPS yesterday and got a 59! It’s not the best score but it’s good enough to get the job I wanted! Got sworn in yesterday and ready to start my military career in the marines! Thank you sir!
Ok so I’m marine prior service. Going to the army now. I first enlisted with a 35 afqt. This time around on my practice asvab I got a 46. After two months of studying from this channel and his website I got a solid 70 AFQT! All my line score are above 100 as well. Thanks so much for your service and commitment to helping others! If you put the time and commitment, you will pass. Good luck everyone!
Thanks to your effort and your videos, i scored from 39 to 67, and I really am thankful for all of those videos you’ve uploaded. I also shared your videos with my recruiters so they can give it to people who struggle with ASVAB. Again, thank you!
I was a high school failure. Couple years later, scored a 68 on the practice and 80 on the PiCAT. I watched your videos before the PiCAT, specifically the math knowledge because that was my weakness (The arithmetic reasoning wasn’t too bad guys don’t be scared but DO study), I want to thank you very much for your videos because they were easy to digest and I appreciate the time you put into them. That in combination with an app got me a good score in just 5 days. Thankyou, I subscribed.
Went from a 48 to a 82 with a 123 GT score only watching your videos. I will recommend your videos to anyone even thinking about joining!

I had a 36 a month ago but I really just watch 5 videos of your channels and boom! 71 my recruiter, his Sargent first-class and all his friend were so impressed cause they told me that was impossible(or even just really hard) to get my score 36 to higher than 50 but I stick to my position that I can do it better, 5 of your videos and the help of God and I made it!! 35 points above!

You have no idea how grateful I am thank you for all the videos that helped the way through it.

THANK YOU!!!! I passed the ASVAB YESTERDAY 05/14/2020. I learned a lot watching your videos. I already signed my contract to be a Helicopter Repair 15-U. I’m so happy and one more time I say thank for you!!!!
I just wanted to thank you for your tutorials. I am a college graduate with two degrees, yet I made a 28 on the practice asvab at the recruiting office. After studying with these tutorials, I came out with a 92. Just goes to show how useful these vids are and how anyone can better themselves with a little effort. Thankyou so much!
Grammar Hero, thank you so much for your videos! I used them as my main studying method and I did several practice tests like you suggested. I scored a 93. I had originally got a 73 on my pretest at the recruiters office. Seriously, these videos really helped!
Thank you for all the content! Just took the ASVAB this past week. Scored a 96- your videos were a huge help to jog my memory of concepts I had not used in a while.
Okay so tell me how I only studied for less than a week with your videos and my score went from a 51 to a 86. Thank you so much. If I had more time to study I know I would have aced it more with a higher score. Your videos were EXTREMELY helpful and on point. Much love. Thank you
Thanks for the videos they really helped man! I turned a 25-42AFQT
I turned AR from a 50 to a 57
I turned MK from a 49 to a 53
Got a 92,GT127 thanks a lot! Study your videos six hours everyday for two weeks. One question still bothers me..A train goes twice as fast downhill as it can go uphill, and 2/3 as fast uphill as it can go on level ground. If it goes 120 miles per hour downhill, how long will it take to travel 45 miles per hour. 1/2hr 2/3hr? I just took a guess 1/2hr.
I’ve been watching your videos for the past 3 days. Went & took my practice ASVAB today & got a 80.
Hey, I thought I’d pop in and let you know that I took my AFQT today. I initially took my ASVAB in 2003 and got a score of 52. After doing nothing but studying your videos for Mathematics Knowledge and Arithmetic Reasoning for the past month, I ended up with an AFQT score of 94 and a GT score of 128. Thank you for all that you do and I hope you continue to help people that
I got a 26 the first time and watching your videos I jumped to a 62!! bless your soul!
On my way home from MEP’s now, scored an 87 on my asvab and easily got the job I wanted. Wouldn’t have been able to do it without your channel!!! Much love!
Got a 92,GT127 thanks a lot! Study your videos six hours everyday for two weeks.
Just took my practice asvab and got a 72 I take the real one on Tuesday! Thank you sooo much man your videos really helped me out.
