The Royal Navy is one of three branches of the UK Armed Forces, with personnel serving across roles including warfare officers, submariners, engineers, and pilots.
Central to Royal Navy recruitment is the Defence Aptitude Assessment (DAA), replacing the former Naval Service Recruitment Test (NSRT). It's a challenging, timed assessment covering six sections. Your score directly determines which roles you qualify for, making focused preparation essential.
Our Royal Navy DAA PrepPack provides realistic practice tests, timed simulations, and targeted drills covering every section of the assessment, helping you build the speed, accuracy, and confidence you need before test day.
Our Royal Navy DAA PrepPack helps you prepare for every section of the Defence Aptitude Assessment.
With our expert-designed PrepPack, you'll get to work on all sections of the Royal Navy aptitude test:
Build speed, accuracy, and confidence with full-length DAA simulations, targeted section drills, and expert study guides.
⭐️ DAA: While the DAA is used as the entry exam for the Royal Navy, you'll also come across it when applying for the Royal Marines and the Royal Air Force.
The Royal Navy Defence Aptitude Assessment (DAA) is a computer-based aptitude test used to determine your suitability for ratings, non-commissioned, and most non-officer roles within the Royal Navy.
It replaced the former Naval Service Recruitment Test (NSRT) and is now the primary aptitude assessment for Royal Navy recruitment.
Unlike many traditional assessments, the DAA is taken online. The link is sent to your candidate portal and remains valid for 14 days, giving you flexibility over when you sit it. Once started, it must be completed in a single sitting. Candidates may also choose to sit it at their local Armed Forces Careers Office (AFCO).
The Royal Navy DAA consists of six different types of questions:
Below is a breakdown of each and what it measures.
The Verbal Reasoning section tests your ability to understand and evaluate written information.
You'll be presented with passages of text across four scenarios and asked to answer questions based solely on what is stated, not personal knowledge or assumptions.
Success depends on reading precisely and distinguishing between what's explicitly stated, what can be logically inferred, and what cannot be determined from the passage alone.
The Numerical Reasoning section is split into two distinct parts, each assessing a different aspect of your numerical ability.
Calculator and multi-function watches are not permitted for either section, but paper and pencil are allowed.
The pace of Part 1 in particular is demanding, and strong mental arithmetic and the ability to work methodically without a calculator are essential.
The Work Rate section tests your ability to work through routine tasks quickly and accurately.
Each question presents a grid with three rows, one containing letters or words, one containing numbers or arithmetic signs, and one containing pictures. Each column in the grid groups one item from each row together.
You are given a code made up of three items (one from each row), all taken from different columns. Your task is to find the alternative code from five options that uses the items from the same columns, in the same order.
The task itself is straightforward once understood, but the challenge is maintaining accuracy at a very fast pace.
The Spatial Reasoning section is split into two parts, each testing a different type of spatial thinking.
Both parts reward candidates who can visualise and mentally manipulate shapes confidently. Regular practice with spatial puzzles significantly improves performance in this section.
The Electrical Comprehension section tests your ability to work with electrical concepts, including circuits, voltage, current, resistance, and the function of basic components such as switches, fuses, and batteries.
Questions are presented as diagrams or practical scenarios in a multiple-choice format.
This section is particularly relevant for candidates applying to engineering or technical roles, though all candidates are required to sit it regardless of their chosen branch.
The Mechanical Comprehension section tests your ability to work with mechanical concepts, including forces, levers, pulleys, gears, and motion.
Questions are typically presented as diagrams or practical scenarios, requiring you to apply mechanical principles to real situations.
As with Electrical Comprehension, this section is especially relevant for technical and engineering roles but is sat by all candidates.
The Royal Navy DAA breaks the six subject areas across eight individually timed sections, totalling 128 questions.
There is no set pass mark for the Royal Navy DAA. Instead, score thresholds are role-specific and subject to change based on current service requirements.
Generally, the higher your score, the more career options become available to you.
Each of the eight sections is scored individually, contributing to your overall profile. Technical, engineering, and specialist roles typically require stronger performance in relevant sections, but you don't need to answer every question correctly to succeed.
Once you've 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).
The DAA is one of the earliest formal stages of the Royal Navy recruitment process.
Here is an overview of the full journey from application to service:
Royal Navy Officer candidates follow a different path after the DAA. Rather than progressing directly through the standard recruitment stages, they're invited to attend the Admiralty Interview Board (AIB), the Royal Navy's officer selection process, covering motivational interviews and group planning exercises.
Read more about individual assessments and roles below:
Following the DAA, candidates are invited to a virtual interview with an Area Careers Liaison Officer (ACLO). The interview typically lasts around 45 minutes and is conducted in a formal setting, either at an Armed Forces Careers Office or via video call.
The interview assesses your motivation for joining the Royal Navy, your understanding of your chosen role, your personal background and experience, and your long-term career aspirations. Interviewers will also explore your teamwork and leadership qualities and your knowledge of current affairs relevant to defence and the Royal Navy.
To prepare effectively:
Our AI-Driven Interview PrepPack, available as an add-on to your DAA PrepPack, lets you practise real interview questions on camera and receive targeted feedback on your responses, tone, and delivery.
The medical assessment takes place as part of the Candidate Preparation Course (CPC), a four-day residential induction that all Royal Navy recruits must complete and pass before progressing to training.
It's carried out by a Service Medical Officer and is comprehensive, covering general physical health, vision, hearing, musculoskeletal fitness, and mental health.
Common concerns candidates have include pre-existing medical conditions, previous injuries, and mental health history. Minor or resolved conditions don't automatically disqualify you as each case is assessed individually. But if you have concerns about a specific condition, speak to your AFCO recruiter before applying, as early guidance can save time later in the process.
Some specialist roles, particularly those involving submarines or aviation, have additional medical requirements beyond the standard assessment.
The Royal Navy Pre-Joining Fitness Test (PJFT) takes place as part of the Candidate Preparation Course (CPC) alongside the medical assessment. Together, these form the key pass or fail elements of the four-day induction into Royal Navy life.
Minimum standards vary by age and gender, so check the specific requirements for your role and age group with your recruiter or AFCO. Candidates applying to the Diver Branch must complete the run in 10 minutes 30 seconds, regardless of age.
Candidates are strongly encouraged to begin training well in advance and to aim above the minimum standard, not just meet it. Arriving at the CPC already exceeding the fitness benchmarks significantly reduces the risk of failing this stage.
Submariner roles do not require additional recruitment tests beyond the standard DAA.
However, strong mechanical and engineering skills are a clear advantage, and candidates are encouraged to brush up on physics and technical knowledge before their assessment.
Upon completing training, submariners receive additional pay supplements reflecting the specialist nature of their service.
The Royal Fleet Auxiliary (RFA) is a civilian organisation owned by the Ministry of Defence that provides logistical and operational support to the Royal Navy, supplying fuel, stores, and equipment at sea, transporting personnel, and delivering humanitarian and counter-piracy operations worldwide.
RFA personnel are civilian employees rather than military personnel, though they serve alongside the Royal Navy on operations.
Candidates applying to join the RFA as ratings or officers are also required to sit the DAA as part of their recruitment process, making our Royal Navy DAA PrepPack equally relevant for RFA applicants. RFA officer candidates additionally attend the Admiralty Interview Board (AIB), the same selection process used for Royal Navy officer candidates.
If you're considering a career with the Royal Fleet Auxiliary, speak to your local AFCO for guidance on eligibility and the specific requirements for your chosen role.
The Royal Navy DAA is a demanding, fast-paced assessment, but with the right preparation, every section is manageable.
Here are some practical strategies to help you perform at your best:
The most effective way to prepare is through consistent, focused practice across all eight sections. Our Royal Navy DAA PrepPack has been designed to give you everything you need to build the speed, accuracy, and confidence to perform at your best on test day.
The key to passing the Royal Navy DAA is consistent, targeted practice across all six test sections.
The Royal Navy Defence Aptitude Assessment (DAA) is the official aptitude test for candidates applying to join the Royal Navy as ratings and most non-officer roles. It consists of eight individually timed sections across six subject areas (Verbal Reasoning, Numerical Reasoning, Work Rate, Spatial Reasoning, Mechanical Comprehension, and Electrical Comprehension) and is taken online or at your local Armed Forces Careers Office (AFCO).
The Defence Aptitude Assessment (DAA) replaced the Naval Service Recruitment Test (NSRT) in March 2022. While the two tests share some similarities in the skills they assess, the DAA has a different structure and is now used across both the Royal Navy and the Royal Air Force. Candidates who have seen references to the NSRT in older preparation materials should focus their practice on the current DAA format.
The DAA is considered challenging by many candidates, not because the individual questions are overly complex, but because of the strict time limits across all eight sections. Work Rate in particular gives candidates just 12 seconds per question, while Numerical Reasoning Part 1 allows only 20 seconds per question. Familiarity with the format and focused timed practice are the most effective ways to improve performance.
Yes, candidates are permitted to retake the DAA if they don't achieve the required score for their chosen role. A minimum waiting period applies between attempts. Speak to your AFCO recruiter for the specific retake policy applicable to your situation, as guidelines can vary.
Once your application has been accepted, you'll be sent a link to take the DAA online via your candidate portal. The link remains valid for 14 days and the assessment must be completed in a single sitting once started. Candidates who prefer to sit the test in a supervised environment can arrange to take it at their local Armed Forces Careers Office (AFCO). Note that the actual test must be taken on a screen of at least 10.2 inches. This ensures the visual elements of sections like Work Rate and Spatial Reasoning display correctly and can be completed accurately.
Yes, your DAA score directly influences which Royal Navy roles and trades you're eligible for. There's no single pass mark; instead, each role has its own score requirements across relevant sections. The higher your overall score, the wider your choice of career paths. Your recruiter will discuss your results with you after the assessment and advise on which roles are available based on your performance.
Yes, the DAA is a recruitment assessment for candidates joining the Royal Navy. Serving senior officers are assessed using different tools, including SHL assessments, which inform promotion and assignment decisions rather than initial recruitment. Officer candidates joining the Royal Navy take the DAA as part of the standard recruitment process before attending the Admiralty Interview Board (AIB) for officer selection.
