Officer Candidates School

Despite what you may have heard, Marine Officer Candidates School (OCS) is not boot camp for officers.

The mission of Officer Candidates School is to train, evaluate, and screen officer candidates to ensure they have what it takes to lead Marines.

Candidates who show up to OCS are expected to be physically fit, knowledgeable, and of sound moral character. OCS exists to ensure you have the qualities expected of a Marine officer.

If you don’t have what it takes, the Marine Corps will NOT hesitate to send you packing.

The Marine Corps spends a great deal of resources evaluating and training it’s officers to ensure they are quality leaders.

OCS Training and Preparation

Officer Selection Officers (OSO) and NROTC units provide the training you need to be successful at Officer Candidates School. To supplement the invaluable guidance that comes from your units, these resources will further enable your ability to train and prepare.

Candidates will be evaluated on their leadership ability from the second they check in to the last moments before graduation. The leadership evaluation category comprises of 50% of your grade at OCS. One must demonstrate the characteristics of a Marine leader to graduate from OCS.

Academic Evaluation – Everyone at Officer Candidates School is either attending college or has already graduated. It should come as no surprise that candidates are expected to maintain high academic standards. The passing grade for all examinations is 80%. Failed, or missed, exams must be made up on the weekend. The retake grade does not get factored into your academic evaluation score. The retakes are there to ensure candidates are able to pass all exams.

Physical Fitness Evaluation – As Marines, we thrive to possess the physical capabilities necessary to perform in austere environments. Candidates are placed under strenuous conditions to include hot and cold weather environments, sleep deprivation, and mental exhaustion.

    How long is the contact for with a 4 year degree?

      Reply

      4 years active, 4 years in the Individual Ready Reserves (IRR). Note that IRR is not the same as the active reserves. You won’t have drill on the weekends or anything. Your essentially a civilian and it’s unlikely you will get called back to active duty.

          The minimum is not going to cut it at OCS, so I’m not going to answer the question. Check out this article with some fitness benchmarks.

          GED is fine, your college transcripts will have the most weight on your application. The age limit is 28.

            One more question if you get 285 or higher on the pft will they be able to do an age waiver ? If I am pass the 28 .

        Thank you very much. I’m a prior enlisted, Marine and did 5 years 8 months active duty. I want to come back to the Marine Corps after completing my degree, in about a year. What should I start doing, I’m a Senior now in College, should I stat getting the process started? My motivation for the Corps is very high, the only reason I left was my Command, and I didn’t want to go back to the fleet after completing Marine Security Guard duty, as an enlisted ground pounding, Devil Dog. Is becoming an Officer the best route, for a prior Enlisted?

          Hey Paul,
          First thanks for your past service and hopefully future service. Since you are wrapping up your senior year by this point. I would definitely say go talk to an OSO (i.e. XO of your local RS) immediately if you haven’t already. You will most likely for to the Officer Candidate Course (OCC), the 10 week course. You’ll be right in your element as this is the route that all of the active duty enlisted guys go to (MECEP and ECP) IOT become an officer. The first few weeks of that course are essentially how to tie your boots and make your rack and other very basic stuff, however it picks up quickly. Obviously make sure you are as fit as possible before showing up. Everything else, you’ll be a step above most others with your experience as a Devil. Most important thing to take from this is go see the OSO like now haha. Good luck brother!

    Sir,

    How competitive is the selection process for OCS? What are the required scores (ACT, SAT, ASVAB)? Work outs? Diets? Any and all advise you’re will to share is greatly appreciated!

    I’m currently overseas (Sasebo) with my AD Navy spouse, a year away from my bachelors, on an accelerated program. I don’t have any stellar volunteer experience… I’ve been working since 18 and was a Resident Assistant in college back home. Currently I work on base and maintain 18 units.

    Female. 21. Estimated graduation date March2017.

    Thank you!

      You need a minimum SAT score of 1000 and a bachelors degree to apply for the OCC Commissioning Program (for those who apply after obtaining a degree).
      Your GPA and Physical Fitness Test (PFT) score will have a large impact on your application. Those should be your primary areas of focus for the next year. The site has some example workouts to prepare for OCS. However, to get ready for the PFT you really need to run and start doing pull-ups.

          You cannot do PLC Seniors without having done Juniors first. If you are already a senior in college, the recruiter will likely recommend that you apply for OCC once you graduate.

      Have two buddies that were enlisted Army and Navy that went through OCS as well as a ton of mustangs from the Corps. The biggest thing at OCS is to shut out your pride since you’ve already been through a version of bootcamp and may rate the same as the sergeant instructors that are tearing your head off. This is especially true for enlisted Marines going through OCS. A couple of my friends were DIs before going to OCS and were being paraded around by people that are literally their buddies that they may have even worked closely with in the past. As for folks from different services, as far as I know, as long as the instructors themselves don’t find out AND you don’t make yourself a target then it won’t matter; you’re just another candidate. Worst case scenario you get spotlighted and harassed for a second about being an airman then they forget to care about you haha.

      After commissioning, whatever you were before no longer matters; you are a Marine now. Everything will be based on performance (a lot of academy kids have trouble understanding this haha). Hopefully this answered your question! Good luck

    Quick question about shaving.

    As an African American, It’s hard for me to shave with a traditional razor (no matter how good it is) without getting razor bumps or razor burn of some sort. It’s a combination of sensitive skin and naturally curly hair.

    With that being said, would I be allowed to use an electric trimmer/clippers during OCS? I’ve heard of them being approved by medical during in-processing.

    How true is this?

    1. USMC Officer
      Reply

      Yes, electric shavers are good to go. In extreme cases, medical can authorize you to not have to shave for a few days. But if you go this route everyone if going to hate you, especially the drill instructors. Stick with the electric razor.

    Why is it a single 10 week session for prior enlisted marines and only a single 6 week session for the people that went through NROTC?

    1. USMC Officer
      Reply

      Prior enlisted Marines in the MECEP program used to do just the 6 week program after their first year of college, but the failure rate led to the Marine Corps deciding to send them to the single 10 week course prior to starting college. OCS is heavily focused on infantry tactics, so sending MECEP Marines to the 6 week program prior to having at least a year of college probably wouldn’t work out too well considering the failure rate was high when those Marines had a year in NROTC to get caught up.

    What would it take for someone in the national guard and still in college to go to OCS for the Marines? Is it just the conditional release process? What if you have service connected injuries that have been taken care of, will a clean military physical be enough to get you in?

    1. USMC Officer
      Reply

      Acceptance into a commissioning program will supersede your enlistment. Yes, you will get a physical during the application process and once you arrive at OCS. If all checks out, you have nothing to worry about.

    I am leaving for OCC class 224 on January 7th. What are your recommendations for purchasing boots before OCS? I currently own McRae temperate weather boots. How many and what pairs are you issued at the beginning? Is there an opportunity to purchase different boots on liberty? Thanks!

    1. USMC Officer
      Reply

      You will get two pair of boots that you’ll be required to wear in the first couple weeks as the staff tries to help you break them in. One will be hot weather boots and the other for cold weather. You can buy at Exchange during liberty, but you’ll have so much gear at that point you’ll probably hold yourself back.

      There’s really no average. Some people have 12-14 months between OCS and TBS while others have 3 days. MOS school will start within a few months after TBS, unless you get Communications which could have a 5-6 month waiting period.

    I’m an OCS hopeful who will be graduating with a bachelors degree right after the summer 2017. I’ve inquired with an OSO for information regarding the application process and Physical Fitness Test details. The OSO recommended that I apply for the July board of 2017 for selection; however, I am not in ideal physical condition at the moment (I literally started training 8 days ago). I would like to be in top physical shape for the application process and put myself in a position to become a leader among leaders if I were to be selected to attend OCS.

    I was wondering if you might have any information regarding the OCS selection board application deadlines after the July 2017 board. I would like set a goal date to work towards after my graduation from university.

    I have a bachelors degree from a UC school and recently started the OCS application (even went to MEPS). But I also applied to graduate schools in case I didn’t get into OCS. Lo and behold, I got into Harvard and Emory. I am now in the dilemma of choosing the Marines or a masters degree from Harvard, which is two years long. Is there any benefits or downsides with applying to OCS again in two years at the age of 25 but with a masters degree from an Ivy League?

      Reply

      You will be highly qualified if you get a Master’s degree. Although, I’ve never met an officer who commissioned after already having a Master’s Degree. I think it’s going to be difficult for you to accept a commissioning with a Second Lieutenant salary when other job opportunities will be available.

        The Marines is something I’ve been wanting to do for a long time now so hopefully I don’t get disillusioned after I graduate. I’m definitely not doing it for the money so I think I’ll still fulfill my dream of joining the Marines.
        Thanks for the reply
