NFA Test Tips: How to Prepare for the National Firefighter Ability Tests
Quick answer
To prepare for the NFA tests, practice all three timed simulations (Working with Numbers, Understanding Information, Situational Awareness) under exam conditions, review every answer in detail, and build your pace over two to four weeks of structured preparation.
The National Firefighter Ability (NFA) tests are the primary written filter in UK firefighter recruitment. Over 75% of applicants fail to progress past this stage — often not because they lack the ability, but because they go in unprepared for the format and time pressure. These tips cover the most important things to know before your tests.
Practice all four assessments — not just the one you find hardest
Most candidates are more comfortable with either numbers or words, and naturally spend more time preparing for whichever test worries them most. This is understandable but leaves a gap. All four NFA assessments contribute to your overall score, and a strong performance across all three is better than an excellent performance on one and a weak performance on the others.
Divide your preparation time fairly across Working with Numbers, Understanding Information, and Situational Awareness. If you have two weeks, aim to do at least two or three full timed sessions of each test.
Practice under timed conditions from the start
It is tempting to do your first few practice tests without a timer to build familiarity and confidence. This is reasonable for your very first attempt — but switch to timed conditions quickly, ideally from your second session. The time pressure in the real tests is a meaningful part of the challenge, and the only way to build composure under it is to practice under it.
Time yourself per test, not per question. Stop when the time is up even if you have not finished — this gives you an accurate picture of where you stand relative to the real test rather than a false sense of security.

8 Working with Numbers questions — no account needed.
Review every answer, right and wrong
After each practice session, go through every question — not just the ones you got wrong. For questions you got right, confirm that you got them right for the right reason and not by lucky elimination. For questions you got wrong, understand specifically why — was it a calculation error, a misread question, a Cannot Say error, or a genuine gap in understanding?
Patterns in your errors are far more valuable than raw scores. If you consistently miss percentage questions, practice percentages. If you consistently mark True when the answer is Cannot Say, practice the discipline of strict source-based reading.
Read the questions carefully — especially the SJT
In the Situational Awareness test, questions often ask for both the most appropriate and least appropriate response. These are different questions — the least appropriate response is not simply the opposite of the most appropriate. Read every part of the question before looking at the answer options.
SJT scenarios test your alignment with fire service values — teamwork, safety, integrity, communication, and commitment to development. When in doubt about which response is most appropriate, ask yourself: what would a good, safe, professional firefighter do in this situation? What would their watch manager want them to do?
On test day: pace, don't race
The most common mistake on test day is trying to go too fast and making careless errors as a result. You have enough time to read each question carefully and think through your answer — what you do not have time for is re-reading questions twice, second-guessing yourself repeatedly, or spending five minutes on a single question.
Work at a steady, deliberate pace. Skip questions that are taking too long and return to them at the end. Mark an answer for every question — there is no penalty for guessing, so leaving a question blank always loses a potential mark.
Frequently asked questions
How early should I start preparing for the NFA tests?
Two to four weeks of consistent practice is enough for most candidates. Start earlier if you are less confident with numerics or reading comprehension, or if you have not sat any kind of timed test recently. Do not try to cram everything into the final 24 hours.
Is there a pass mark?
Services do not typically publish the exact pass mark. The pass threshold may vary between campaigns depending on the number of vacancies and the overall standard of the applicant pool. Aim to perform as well as possible rather than targeting a specific score.
How many times can I sit the NFA tests?
If you fail the NFA tests in one campaign, you can typically reapply in a future campaign — subject to any waiting period the service imposes. Check the specific policy with your chosen service.
Does my score on the NFA tests affect my overall ranking?
Yes — NFA test scores typically contribute to your overall candidate ranking alongside physical and interview performance. A strong score, not just a bare pass, improves your position in competitive campaigns.
