⭐️ DAA: While the DAA is used as the entry exam for the Royal Marines, you'll also come across it when applying for the Royal Navy and the Royal Air Force.
The Defence Aptitude Assessment (DAA) is the official aptitude test for candidates applying to join the Royal Marines.
It replaced the former Naval Service Recruitment Test (NSRT) in March 2022 and is now shared across the Royal Marines, Royal Navy, and Royal Air Force, ensuring all candidates are assessed to a consistent standard.
Taken online, the DAA consists of six distinct sections:
Below is a breakdown of each section and what it measures.
The Verbal Reasoning section tests your ability to read and evaluate written information accurately.
Success depends on reading precisely and working quickly - there is no room for second-guessing.
The Numerical Reasoning section is split into two parts:
No calculator is permitted in either part but paper and pencil are allowed for calculations.
Strong mental arithmetic is essential, particularly for the fast pace of Part 1.
The Work Rate section tests your ability to process routine tasks quickly and accurately.
You're shown a grid containing letters, numbers, and pictures, given a three-element code, and must identify the correct alternative code from five options, using items from the same columns in the same order.
You have 4 minutes to answer 20 questions, giving you just 12 seconds per question.
The Spatial Reasoning section is split into two parts:
Each part has 10 questions that need to be answered in 4 minutes.
Regular practice with spatial puzzles significantly improves performance here.
The Electrical Comprehension section tests your knowledge of circuits, voltage, current, resistance, and basic electrical components.
All candidates sit this section regardless of their chosen role or specialisation.
The Mechanical Comprehension section tests your understanding of forces, levers, pulleys, gears, and motion.
This section carries particular weight for Royal Marines candidates, as research shows strong mechanical aptitude is closely linked to success in commando training.
In total, the Royal Marines DAA covers 128 questions across eight individually timed sub-tests, using the above six categories as a base.
There is no set pass mark for the Royal Marines test as score thresholds are role-specific and subject to change based on current service requirements.
The higher your score, though, the more career options become available to you.
Each of the eight sections is scored individually, contributing to your overall profile. Mechanical Comprehension is a particularly critical section for Royal Marines candidates. Research has consistently shown that strong mechanical aptitude, alongside physical fitness, is closely associated with successfully completing Royal Marines recruit training. Aim to score as highly as possible in this section.
Once you have completed the DAA, your recruiter will contact you to discuss your results and next steps. If you're unsure what score you need for a specific role, speak to your Armed Forces Careers Office (AFCO).
Joining the Royal Marines is one of the most demanding selection journeys in the British military.
The Royal Marines aptitude test is one of the first formal assessments, but it's just the beginning. Here's an overview of the full selection process:
Once you've passed the CPC and completed security clearance, you'll be given a start date for Initial Training at CTCRM Lympstone, a 32-week programme beginning with the four-week Recruit Orientation Phase (ROP) and culminating in the four Commando Tests.
Officer candidates follow a different pathway, attending a filter interview, then the Potential Officers Course (POC) at CTCRM Lympstone, and finally the Admiralty Interview Board (AIB) before commencing officer training.
Learn more about key stages below:
The Candidate Preparation Course is the final selection stage before you're accepted into Royal Marines Initial Training. It replaced the former Potential Royal Marines Course (PRMC) in 2020 and is designed to assess your physical ability and intellectual capacity to undertake the demands of Royal Marines recruit training.
The CPC takes place over three days at Commando Training Centre Royal Marines (CTCRM) in Lympstone, Devon:
The CPC can be attempted a maximum of three times. Candidates who pass are invited to begin the Recruit Orientation Phase, the first four weeks of Initial Training at CTCRM Lympstone.
The Potential Officers Course (POC) is a three-day residential assessment at CTCRM Lympstone evaluating your leadership potential, physical fitness, and suitability for Royal Marines officer training. Candidates who pass are invited to attend the Admiralty Interview Board (AIB), the final selection stage before commencing the 15-month officer training programme.
Physical fitness is central to every stage of Royal Marines selection. Standards are among the most demanding in the British military, and candidates are strongly encouraged to exceed rather than simply meet the minimum requirements.
The key fitness assessments in the Royal Marines recruitment process are:
Begin your fitness preparation as early as possible.
Arriving at the CPC already exceeding the minimum standards significantly improves your chances of passing and completing the subsequent 32 weeks of Initial Training.
The Royal Marines DAA is the first formal hurdle in one of the most demanding selection processes in the British military. Clear it with confidence using these preparation strategies:
Our Royal Marines Test PrepPack gives you realistic timed practice across all six sections, so you walk into the DAA ready to score as high as possible.
The key to passing the Royal Marines DAA is consistent, targeted practice across all six test sections.
The Royal Marines aptitude test is the Defence Aptitude Assessment (DAA), a timed, multiple-choice assessment covering six sections: Verbal Reasoning, Numerical Reasoning, Work Rate, Spatial Reasoning, Mechanical Comprehension, and Electrical Comprehension. It's taken online or at your local Armed Forces Careers Office (AFCO) and is one of the first formal stages of the Royal Marines recruitment process.
The Naval Service Recruitment Test (NSRT) was replaced by the Defence Aptitude Assessment (DAA) in March 2022. The DAA is now used across the Royal Marines, Royal Navy, and Royal Air Force as a single unified aptitude assessment. Candidates researching the Royal Marines aptitude test may encounter references to the NSRT in older materials, but our page reflects the current DAA format.
The DAA is challenging, not because the questions are overly complex, but because of the strict time limits across all eight sections. Work Rate gives you just 12 seconds per question, and Numerical Reasoning Part 1 allows only 20 seconds per question. Mechanical Comprehension is also particularly important for Royal Marines candidates. Thorough preparation and timed practice are the most effective ways to improve your performance.
Royal Marines candidates face several fitness assessments throughout the selection process.
Standards are among the most demanding in the British military, and it's best to begin training well in advance and aim to exceed the minimum requirements.
The Potential Royal Marines Course (PRMC) was the former selection course for Royal Marines recruits, a demanding three to four day physical assessment at CTCRM Lympstone. It was replaced in 2020 by the current Candidate Preparation Course (CPC), which takes a more progressive approach to physical testing. Candidates researching the PRMC should be aware that the CPC is now the relevant selection stage.
Once accepted through the recruitment process, Royal Marines recruits undergo 32 weeks of Initial Training at Commando Training Centre Royal Marines (CTCRM) in Lympstone, Devon.
Training begins with the four-week Recruit Orientation Phase (ROP) and culminates in four Commando Tests, the endurance course, nine-mile speed march, Tarzan assault course, and 30-mile march across Dartmoor.
Officer training is 15 months, the longest officer training programme in the British Armed Forces.
Royal Marines officer candidates follow a separate pathway from other ranks. After the DAA and a filter interview, officer candidates attend the Potential Officers Course (POC) at CTCRM Lympstone before completing the Admiralty Interview Board (AIB). Those who pass both stages begin the 15-month officer training programme at CTCRM Lympstone. Officer candidates must be aged between 18 and 25 at the start of training.
There is no single pass mark for the Royal Marines DAA since score thresholds are role-specific and subject to change based on current service requirements. Mechanical Comprehension is a particularly important section for Royal Marines candidates, but you should aim for the highest possible score across all sections. The higher you score, the more role options become available to you. Speak to your AFCO recruiter for guidance on the specific requirements for your chosen role.
Women have been eligible to join all Royal Marines roles, including combat roles, since 2018 following the removal of gender-based restrictions across British military infantry units. The same selection process, fitness standards, and training programme apply to all candidates regardless of gender.
