1.1 About the Defence Aptitude Assessment
Key Takeaways
- The current DAA is a six-test battery for Royal Navy, Royal Marines and RAF pathways — not the British Army BARB route.
- It replaced the RAF AST and Naval RT/NSRT; Memory was an AST element and is not listed on current DAA pages.
- RAF familiarisation publishes per-section loads (about 128 items / 69 timed minutes across the six tests).
- There is no single pass mark — required scores are set per profession and specialisation.
1.1 About the Defence Aptitude Assessment
Quick Answer: The Defence Aptitude Assessment (DAA) is the UK Armed Forces aptitude battery used by the Royal Navy, Royal Marines, and Royal Air Force (and, for some Naval Service paths, related roles such as Royal Fleet Auxiliary applicants). It replaced the older RAF Airman Selection Test (AST) and the Naval Service Recruit Test (RT/NSRT). It does not replace the British Army’s BARB pathway — Army candidates follow a separate assessment route.
The DAA is not a single pass/fail exam with one national cut-score. It is a role-matching aptitude battery: your profile of scores across six timed multiple-choice tests is compared with the minimums required for the profession and specialisation you want. A stronger profile keeps more roles open; a weaker profile may still qualify you for other trades, or you may need to discuss options (or a retake under branch rules) with your Careers Adviser.
Who sits the DAA?
Official recruitment pages for the Royal Navy and RAF describe the DAA as part of their joining process. In practice that means:
| Service path | Uses current DAA? | Notes |
|---|---|---|
| Royal Navy / Royal Marines | Yes | Portal link issued after application; home or AFCO |
| Royal Air Force (other ranks / many non-commissioned routes) | Yes | Previously the AST; familiarisation hosted on RAF recruitment |
| British Army | No | Army selection uses its own cognitive/assessment path (historically BARB and related Army assessment tools), not the RN/RAF DAA |
Always confirm the exact step for your chosen role on the official careers site for that service — officer routes and professionally qualified paths can differ.
The six DAA tests (current battery)
Royal Navy and RAF pages both state that the DAA is made up of six multiple-choice tests. The RAF familiarisation tool also publishes the real-test question counts and timers used for familiarisation messaging:
| Test | What it measures | RAF familiarisation “real test” load |
|---|---|---|
| Verbal Reasoning | Understand, interpret, and use written information (typically across short scenarios) | 20 questions / 15 minutes |
| Numerical Reasoning | Part 1: fractions, decimals, formulae; Part 2: graphs and tables (no calculator) | 12 Q / 4 min then 15 Q / 11 min |
| Work Rate | Solve routine coding / matching tasks quickly and accurately | 20 questions / 4 minutes |
| Spatial Reasoning | Part 1: 2D shape visualisation; Part 2: 3D rotation (objects with corner dots) | 10 Q / 4 min then 10 Q / 3 min |
| Electrical Comprehension | Work with basic electrical concepts (circuits, components, relationships) | 22 questions / 15 minutes |
| Mechanical Comprehension | Work with basic mechanical concepts (levers, gears, pulleys, forces, fluids) | 19 questions / 13 minutes |
Adding those familiarisation figures gives 128 scored items and 69 minutes of section timers (plus reading instructions and moving between sections). Royal Navy familiarisation copy separately tells candidates to set aside roughly 30–40 minutes of focused time for practice — treat published familiarisation tips as guidance, and use the RAF per-section timers as the most specific official item/time breakdown currently published.
What is not on the current DAA
The old RAF AST included a seventh Memory test (film/DVD sequences and grid recall). Current Royal Navy and RAF DAA pages list six tests only and do not list Memory/Recollection as a DAA section. Do not prepare as if a separate memory battery is still scored on today’s DAA.
How scores are used
There is no single published pass mark. Requirements differ by profession and specialisation. Official RN copy is explicit: easy and hard items appear; you do not need every answer correct to succeed for your chosen path — but higher scores typically keep more options open.
If your profile does not meet your first-choice role, Careers staff may discuss alternative roles your scores support, or retake rules for your branch. Public third-party summaries often mention a ~28-day gap before another attempt and branch-specific attempt limits (for example, Naval Service pathways commonly described as limited attempts; RAF pathways sometimes described with longer cool-downs). Treat retake limits as branch-specific and confirm with your Careers Adviser rather than assuming one universal rule.
Preparation philosophy
The DAA measures aptitude under time pressure, not military trivia. Highest-yield prep is:
- Learn the six official formats using MOD familiarisation practice.
- Drill speed on work-rate coding and spatial rotations.
- Rebuild GCSE-level arithmetic plus basic electrical and mechanical principles without a calculator.
- Practise answering only from the passage in verbal items (no outside assumptions).
The chapters that follow teach each domain with worked examples, traps, and timed-style checks so you can convert familiarisation practice into exam-day speed.
