Marine Corps Promotion Timeline and How Cutting Scores Really Work

Two Marines enlist the same week, do the same job, and hit their time in grade on the same day. One picks up corporal. The other does not, and nobody in the shop can explain why in a way that makes sense.

The answer is a number called a cutting score, and it is the part of Marine Corps promotion that people get wrong most often. You are not being measured against a standard you can pass. You are being ranked against every other Marine in your military occupational specialty (MOS, the Marine Corps term for your job), and the Marine Corps draws a line wherever it happens to have vacancies that month.

Here is how the whole system works, with the actual arithmetic and real published numbers.

The Short Version

Time in grade for corporal and sergeant comes from the current table published by the Marine Corps Promotion Section. The staff sergeant and above figures come from the Marine Corps Promotion Manual, MCO P1400.32D.

Every one of those numbers is a floor, not a schedule. Clearing the minimum makes you eligible to compete. It does not promote you, and for corporal and sergeant it is usually the least interesting part of the equation.

PFC and Lance Corporal: Mostly Time

Promotion to private first class needs 6 months time in grade and 6 months time in service. Lance corporal needs 8 months time in grade and 9 months time in service. There is no competitive score at these ranks and no cutting score to beat.

What can stop you is your command. These promotions require that your service has been satisfactory, so misconduct or a failed fitness test can hold you back. Absent that, most Marines make lance corporal on schedule.

You can also start higher than E-1. College credit, JROTC, and referral programs can get you a contract at private first class or lance corporal, which moves every later milestone earlier by months. That is negotiated before you sign and is very hard to recover afterward, which is one of the items worth raising in a real conversation with a recruiter.

The JEPES Score: Four Pillars, 1,000 Points

Since February 2021, corporal and sergeant promotions have run on the Junior Enlisted Performance Evaluation System, or JEPES. It replaced the old proficiency and conduct marks, the "pros and cons" you will still hear older Marines talk about.

JEPES produces a Performance Evaluation System score, usually just called your PES score or composite score. It is built from four pillars, each worth exactly 25 percent, each capped at 250 points, for a maximum of 1,000. The governing document is MCO 1616.1, and the September 2026 promotion MARADMIN still cites it as current.

Notice what that structure does. Command Input, the subjective part, is one quarter of your score. The other three quarters are objective things recorded in the Marine Corps Total Force System (MCTFS): a rifle score, a belt, two fitness tests, a list of completed courses. That was the point of the change. Under the old system a Marine's fate rode much more heavily on what a sergeant thought of them.

On top of the four pillars sit bonus points, capped at 100. Drill instructor school, recruiter school, Marine Security Guard school, combat instructor duty and Marine Corps Security Forces are worth 50 points each. Referring people who enlist is worth 20 points each, up to 100. The total still cannot exceed 1,000.

A Composite Score, Worked Out

The arithmetic in MCO 1616.1 is genuinely simple once you see it done. Take a lance corporal competing for corporal.

Warfighting. Rifle and MCMAP values are added, then multiplied by 1.25. Say the rifle score converts to 80 and the Marine holds a green belt, worth 100 on the lance corporal table. That is 180, times 1.25, which gives 225.

Physical Toughness. Same shape. PFT value 75 plus CFT value 70 gives 145, times 1.25, which is 181.25, rounded to 181.

Mental Agility. MarineNet course credits (max 100), degrees (max 40), off-duty courses in service (max 30) and off-duty courses in grade (max 30) are added, then multiplied by 1.25. Say 60 in MarineNet credits, no degree, one course in service and one in grade at 10 points each. That is 80, times 1.25, giving 100.

Command Input. Each of the three marks is multiplied by 50, the three are added, and the total is divided by 3. Marks of 4.3, 4.3 and 4.0 give 215 plus 215 plus 200, which is 630, divided by 3, giving 210.

Add them: 225 plus 181 plus 100 plus 210 is a PES score of 716 out of 1,000.

Look at where that Marine is losing points. Not in the subjective part, where the marks are strong. The gap is Mental Agility, sitting at 100 out of 250, because MarineNet courses are free, can be done from a barracks room, and most Marines do not bother. That pillar is worth exactly as much as the PFT and CFT combined.

What a Cutting Score Actually Is

Your 716 means nothing on its own. It has to beat the cutting score for your MOS, in the month you are being considered.

Marine Corps Manpower and Reserve Affairs publishes these monthly, by MOS, for corporal and sergeant, and splits them further into active duty, active reserve and drilling reserve. Everyone at or above the number gets promoted, provided they also meet time in grade, time in service, and have their professional military education complete in the system.

Here are real active duty cutting scores for October 2026, taken from the Manpower cutting scores page. MOS titles are from the Marine Corps MOS Manual, NAVMC 1200.1M.

Across all 169 MOSs listed that month, the open corporal cutting scores ran from 211 to 719, and the sergeant scores from 214 to 815. That is the whole story in one sentence. A Marine with a 716 picks up corporal in almost every MOS on the list and misses in the single hardest one by three points.

These numbers also move month to month. In September 2026 the 0311 corporal cutting score was 660; in October it was 650. For 0331 it went from 608 to 585. A Marine who missed by four points in one month can be promoted the next without doing anything differently, because the vacancies changed.

When Your MOS Is Closed

Some MOSs do not get a number at all. They are marked CLOSED, which means the Marine Corps promoted nobody in that MOS to that rank that month. In MCTFS it shows as 9999.

This is more common than most people expect. In the October 2026 active duty tables, 51 of 169 corporal MOSs and 49 of 169 sergeant MOSs were closed. In September it was worse for sergeants: 72 of 169 closed, meaning more than four in ten sergeant MOSs promoted nobody at all that month.

A closed month is not a judgment on you. It means there were no vacancies to fill. You could have a 950 and it would change nothing. This is the single hardest thing about the system to accept, and it is the honest reason two Marines with identical records end up a rank apart: one was in a field with people leaving, and one was not.

There is one genuinely useful thing here. Late entries get fixed automatically. If a course or a command input mark posts after the cutoff date, MCTFS recomputes your score and runs an automatic remedial promotion, backdating your date of rank, without your command filing paperwork.

Staff Sergeant and Above: No Score At All

At E-6 the system changes completely. There is no JEPES score, no cutting score, and nothing you can calculate.

Staff noncommissioned officer promotions are decided by selection boards convened annually at Headquarters Marine Corps. A board is made up of commissioned officers from chief warrant officer through colonel and senior enlisted from master sergeant through sergeant major, all at least one grade senior to the Marines being considered. They read records and vote on who is best qualified.

Three terms matter here. In zone means you are in the normal competition group for this year's board. Above zone means you were considered before and not selected, and you will keep being considered. Below zone means you have the minimum time in grade but are ahead of the normal group, and can be picked early.

Being passed over is not the end. Above zone Marines continue to compete as long as they intend to stay in. But the board does not explain itself, and there is no appeal on the merits, so your record has to make the case without you in the room.

Moving Your Score

Do the MarineNet courses. This is the clearest advice in the whole system. Mental Agility is 250 points, the same as physical fitness, and it costs you evenings rather than mornings. Most Marines leave a large part of it on the table.

Treat the rifle range as a promotion event. Your rifle score is 12.5 percent of your composite, scored as a percentile against peers of your rank. It is the only pillar component that gets one serious attempt a year.

Chase the belt. MCMAP is a flat table, not a percentile. Each belt level is worth a fixed number of points, and moving up one is a known, bankable gain.

Finish your PME early. Incomplete professional military education flags you in MCTFS, and a flagged Marine does not appear on the select grade list even with a score above the cutoff. This is a pure administrative loss and it happens constantly.

Know your MOS before you sign. Nothing else on this list moves the needle as much. Two of the pillars are effort, one is paperwork, and the cutting score is arithmetic done by somebody else about a field you chose at 18. If you are still choosing, the Branch Quiz and Branch Comparison Tool are a reasonable place to start before the job conversation.

The Bottom Line

Marine Corps promotion to corporal and sergeant is more transparent than any other enlisted system in the military. The formula is published, your inputs are visible to you in Marine Online, and the cutoffs are posted publicly every month by MOS. You can calculate almost exactly where you stand.

What that transparency reveals is uncomfortable. Roughly three quarters of your score is yours to earn, and then the line you have to clear is set by vacancies in a field you picked before you understood what any of it meant. In a closed month it is set nowhere at all.

So do the two things that are actually in your hands. Before you enlist, pull up the Manpower cutting scores page and look at a year of history for any MOS you are offered. After you enlist, do the MarineNet courses, because that is where the cheapest 150 points in the system are sitting.
