Getting ready to be a Marines Officer

The joining process for Royal Marines Commando Officers is exceptionally rigorous. Like any physical and mental test, being prepared will give you the best chance of success. This section gives you more details about the Defence Aptitude Assessment (DAA), the Pre-Joining Fitness Test Plus and the Officer Selection Course.


The Naval Service Recruiting Test (NSRT) enables us to test your general intellectual ability, regardless of your existing academic qualifications. This gives us more information, and is a fair way of assessing all candidates on a level playing field.

The test has four different sections, which you’ll need to complete within a strict time limit. They measure your:

  • General reasoning- testing your mental agility with logic based questions
  • Verbal ability - assessing your understanding of language and ability to communicate
  • Numeracy - testing your numerical reasoning and basic mathematical ability
  • Mechanical comprehension - Assessing your understanding of basic mechanical principles

If you don’t pass the NSRT first time around, don’t worry – you can take it again. Your Careers Adviser will tell you what the timescales are likely to be.

To help you prepare, you can work through the practice tests.

Practice the Recruiting Test


The Pre-joining Fitness Test Plus (PJFT+) for Officers is not just a a step up from the pre-joining test across the rest of the Royal Navy, but also a tougher test than Commando candidates will experience. You'll be expected to push yourself to pass and to produce your very best at all disciplines if you’re going to excel at it. To have any chance of success in the PJFT+, and beyond to the Officer Selection Course, it’s critical that you get in the best possible physical condition - better than you've ever been before.

Since June 2021, the PJFT+ has resumed being conducted at Nuffield Health Gyms across the country under the assessment of a Physical Training Instructor.

The circuit conducted for the test includes:

  • 20 x burpees
  • 30 x sit ups 
  • 20 x press ups 
  • 1 minute plank

You will have to complete the full PJFT+ circuit four times. On completion of the four circuits, and after a two-minute recovery, you'll have to perform one set of five pull ups.

To continue your journey as a Royal Marines Commando Officer you'll have just two attempts to pass the Pre-Joining Fitness Test Plus, and be progressed to next stage.

Get Marines Fit

Royal Marine Officer Selection Course

The two-and-a-half-day Officer Selection Course (OSC) is demanding. However fit you are, you will be pushed to your physical limits and will be working outside your comfort zone. It’s your chance to show that you have the practical leadership skills needed to become a Royal Marines Commando Officer.
