Marine Corps boot camp is 13 weeks long, not counting Receiving Week at the front end. That 13-week figure is the recruit training itself, but it is not the whole story of how long you will be in training before reaching your first unit. Once you factor in the School of Infantry and job-specific schooling that follow, the full pipeline from shipping day to your first duty station runs anywhere from about six months to well over a year.
Here is what those 13 weeks actually contain, what can stretch them, and what happens after graduation.
The 13 Weeks, Broken Down
Recruit training runs on a four-phase schedule that is identical at both Marine Corps Recruit Depot Parris Island and Marine Corps Recruit Depot San Diego. Before the phases start, there is Receiving Week, sometimes labeled Phase 1 on the training matrix but functioning more like an on-ramp: haircuts, uniform and gear issue, medical screening, administrative processing, the Initial Strength Test, and a first encounter with drill instructors.1Defense Visual Information Distribution Service. Receiving Week – Phase One, MCRDSD Training Matrix
Phase 1: Discipline and Conditioning (Weeks 1–3)
The first three weeks focus on breaking civilian habits and building military discipline. Recruits start intense physical training, close-order drill, and the Marine Corps Martial Arts Program, along with instruction in Marine Corps history, customs, and core values. The physical demands are steep, but the harder adjustment for many recruits is an environment where every minute of the day is controlled.
Phase 2: Marksmanship and Field Skills (Weeks 4–8)
The next five weeks shift to combat skills. The centerpiece is rifle qualification, with recruits shooting their service rifle at distances from 200 to 500 yards and earning one of three qualification levels (Marksman, Sharpshooter, or Expert) out of 250 possible points. This phase also includes combat conditioning, rappelling, and the gas chamber, where recruits are exposed to CS gas to build confidence in their protective equipment.
Phase 3: The Crucible and Final Training (Weeks 9–12)
Phase 3 culminates in the Crucible, a 54-hour field exercise involving more than 45 miles of marching, sleep and food deprivation, combat scenarios, obstacle courses, and team leadership challenges under extreme stress.2Marines. Marine Corps Boot Camp | Recruit Basic Training At the end of the Crucible, recruits receive the Eagle, Globe, and Anchor emblem, and that is the moment they officially become Marines. The remaining days go to final inspections, administrative tasks, and preparation for graduation.
Graduation Week
The 13th week is graduation week, with Family Day and the graduation ceremony on the Peatross Parade Deck at Parris Island (or the equivalent parade deck at San Diego).
What Can Stretch Your Time at the Depot
The 13-week schedule assumes you meet every standard on the first attempt. Several things can push your graduation date back, sometimes by weeks or months.
Failing the Initial Strength Test. The IST happens in Receiving Week. If you fail it, you get dropped into a Physical Conditioning Platoon to build up before joining a training company, and that time does not count toward your 13 weeks. The minimums are 3 pull-ups or 34 push-ups for males (1 pull-up or 15 push-ups for females), a 1.5-mile run in 13:30 for males or 15:00 for females, and a plank hold of at least 1:03.3Marines. Physical Requirements Showing up well above the minimums is strongly recommended.
Failing to qualify with the rifle. Recruits who do not qualify during Phase 2 recycle back to try again, and that pushes graduation.
Injury or illness. Injuries during boot camp are common. Recruits who get hurt or become seriously ill are assigned to the Medical Rehabilitation Platoon within the Special Training Company. There is no fixed timeline: a recruit stays in medical rehab until cleared, then moves to the Physical Conditioning Platoon to rebuild fitness before being inserted into a new training company. None of that time counts toward the 13 weeks, so an injury can easily add weeks or months to your time at the depot.
Falling behind on standards. A drill instructor may give a recruit a second chance to retest a physical benchmark, especially if the failure was marginal and the recruit is putting in effort. Recruits who fall significantly short get dropped to conditioning platoons. In extreme cases where a recruit cannot meet standards even after extended conditioning, administrative separation from the Marine Corps is possible.
What Comes After Graduation
Graduation is closer to the halfway point of your initial training than the finish line. Every new Marine has at least two more stops before reaching the fleet.
Post-Graduation Leave
New Marines get one travel day plus 10 days of leave after graduation before reporting to their next training location.4Marines. FAQs for Parents Marines participating in the Recruiter Assistance Program can receive up to 30 days of leave before reporting to the School of Infantry, though that program is not open to everyone.
School of Infantry
Every Marine, regardless of eventual job, goes to the School of Infantry after leave. SOI has two campuses: School of Infantry–East at Marine Corps Base Camp Lejeune, North Carolina, and School of Infantry–West at Camp Pendleton, California.5School of Infantry – East. School of Infantry – East Which one you go to generally matches the depot where you did boot camp. From there, training splits in two:
- Marines with an infantry MOS attend the Infantry Training Battalion (ITB), which has been expanded from 9 weeks to 14 weeks for deeper training in infantry tactics and combat skills. Infantry Marines typically go straight from ITB to their first unit.6School of Infantry – East. Infantry Training Battalion
- All non-infantry Marines attend Marine Combat Training (MCT), a 29-day course covering marksmanship, patrolling, and field tactics. The premise is that every Marine is a rifleman first.4Marines. FAQs for Parents
MOS School
After MCT, non-infantry Marines report to their MOS-specific school to learn their actual job. Length varies enormously by role. Administrative and logistics jobs may need only a few weeks. Technical fields like avionics, cyber operations, or signals intelligence can run several months. The longer pipelines mean some Marines do not reach their first operational unit until a year or more after enlisting.
The Full Timeline
For a non-infantry Marine, the standard pipeline runs roughly like this: 13 weeks of recruit training, 10 days of post-graduation leave, 29 days of Marine Combat Training, and then a few weeks to several months of MOS school. For an infantry Marine, it is 13 weeks of recruit training, 10 days of leave, and 14 weeks at ITB before reporting to a first unit.
So the short answer to how long Marine boot camp lasts is 13 weeks. The honest answer to how long until you are done training and actually working your job in the fleet is closer to six months to a year and a half, depending on your MOS and whether anything slows you down along the way.
