Marines Officer: Stages and standards

The fact you want to get fit to become a Royal Marines Commando Officer says a lot about you. It says a lot about your character. The level of physical exertion required to earn the coveted Green Beret is more than most people can take. To help you make the grade and realise your career ambitions, we’ve outlined all the stages you need to complete, and the standards you’ll need to achieve to be successful. These stages are as follows:

  1. Pre-joining Fitness Test (PJFT)
  2. Interview (There is no physical test at this stage, but you need to pass it to progress to the next)
  3. The Potential Officer Course (POC)
  4. The Admiralty Interview Board (AIB)
  5. Initial Naval Training (Officer) (INT(O))

Preparation, as with all aspects of the joining process, is key to ensuring you’re fit enough for life as a Royal Marines Commando Officer. Most of these tests have a minimum requirement, but it is a key part of the Royal Marines ethos to push to the limit, regardless of what is acceptable.

The more you can prove that you can think clearly and make decisions when exhausted and under extreme pressure, the more you will show you have what it takes to lead your team. To help you get ready for each stage, you can navigate through the process, see exactly what is required to pass, and find out how you can give yourself an edge.

Pre-joining Fitness Test (PJFT)

You will be expected to produce your best effort, going beyond the minimum requirement. If you’re going to excel at the PJFT (and in your initial training), it’s critical that you get in the best possible physical condition.

Swimming requirements

  • Step off a 3m diving board in swimming costume or shorts (without kit)
  • Swim approximately 80m, using the Breast Stroke Technique with no time limit
  • Confidently retrieve a brick from the bottom of the pool at 5 meters then tread water for 2 minutes
  • Climb out of the pool, without using a ladder


During this first mandated summative assessment, no goggles are to be worn unless a recruit has a medical reason. In the BST (Battle Swimming Assessment)  no goggles are to be worn, those with medical reasons are not exempt. 


The test takes place at a Nuffield fitness centre. They’re all over the country, so you’ll be able to find one near you


Typically, we’ll invite you to the PJFT within 28 days of you passing your medical
