IOSH Working Safely Exam Format and Pass Rate: Everything You Need to Know

IOSH Working Safely Exam Format and Pass Rate: Everything You Need to Know

The short version

  • The IOSH Working Safely exam is taken at the end of the one-day course.
  • It has two parts: a 20-minute multiple-choice exam and a 10-minute hazard-spotting exercise.
  • The written pass mark is 80%.
  • Pass rates at approved providers are consistently very high — most delegates pass first time.
  • There’s no revision required before the course; everything you need to pass is covered on the day.

If that’s all you needed, stop reading and go book. If you want the full picture — including how to prepare, what happens if you fail, and what the exam actually feels like — keep going.

What the exam actually is

The IOSH Working Safely end-of-day assessment is made up of two parts, both sat on the same day as the training, usually immediately after the final module.

Part 1 — Multiple-choice exam

  • Length: 20 minutes
  • Format: multiple-choice questions covering all five modules of the syllabus
  • Delivery: on paper or on-screen (depending on your training provider and whether the course is in-person or virtual)
  • Pass mark: 80%

The questions are designed to test understanding rather than memorisation. You won’t be asked to recite legislation word-for-word. You’ll be asked whether a described situation is a hazard or a risk, what the right response is to a near-miss, or which control measure sits highest in the hierarchy. All of it is covered during the day — see our IOSH Working Safely syllabus walkthrough for exactly what’s taught in each module.

Part 2 — Hazard-spotting exercise

  • Length: 10 minutes
  • Format: a workplace scene (image, diagram, or short video) with multiple hazards shown. The delegate identifies the hazards and suggests appropriate controls.
  • Pass mark: marked on completeness and accuracy; the trainer moderates against a standard checklist.

The hazard-spotting exercise is where the course earns its keep. If you’ve paid attention during Module 3 (Identifying Common Hazards) you’ll find it genuinely satisfying — it’s a chance to apply the framework in front of you, and most delegates enjoy it.

The pass mark, and what it really means

The written exam pass mark is 80%. The number of questions varies slightly depending on the paper your provider uses, but the pass proportion is always the same.

The hazard-spotting exercise is marked pass/fail based on whether the delegate identifies a reasonable proportion of the hazards in the scene and can articulate sensible controls.

To pass the course overall, you need to pass both parts.

What’s the typical pass rate?

The pass rate for IOSH Working Safely is consistently very high across approved providers. Most delegates pass on the day, first time.

Two reasons it’s so high:

  1. The course is deliberately pitched to be accessible. Nobody is there to be caught out.
  2. The exam tests what the trainer just taught, the same day. There’s no gap in which to forget things.

If you’ve attended the day and paid reasonable attention, you will almost certainly pass. The small number of people who don’t are usually those who have struggled with the reading-and-writing element rather than the safety content — which is something a good training provider can support with, if flagged in advance.

What happens if you don’t pass first time

If a delegate doesn’t pass the multiple-choice exam on the day, most approved providers — including KeyOstas — offer a free re-sit, either later the same day if time permits or at a mutually convenient time afterwards. There’s usually no additional fee for a first re-sit.

If a delegate doesn’t pass the hazard-spotting exercise, the trainer will typically go through the scene with them to pick out what they missed, and re-test on a different scene.

It’s rare for someone to fail the course entirely. In the handful of cases where it does happen, it’s almost always resolved with a short re-cap session rather than requiring the whole day to be repeated.

How to prepare for the exam

Honestly, the best preparation is to turn up rested, pay attention, and ask questions if anything is unclear.

Things that help:

  • Sleep the night before. The course is a full day. A tired delegate does worse in the end-of-day assessment, full stop.
  • Bring a notebook. The workbook provided has space to make notes, but a separate notebook for your own thoughts can be useful.
  • Ask questions as you go. If a concept doesn’t quite land in Module 2, it’ll come back in Module 3 and Module 4. Clear it up early.
  • Engage with the exercises. The hazard-spotting exercise in the exam is the same format as the exercises in Module 3. Treating those seriously is the single best prep you can do.

Things that don’t help:

  • Trying to pre-read legislation. You won’t be quizzed on it.
  • Memorising the hierarchy of control in advance. The trainer will walk you through it, and it’ll stick in context.
  • Drinking coffee instead of sleeping. See above.

What the exam feels like

Most delegates describe the exam as “easier than expected”. The multiple-choice questions feel like a recap of the day rather than a test. The hazard-spotting exercise is usually the more enjoyable part — it’s active, it’s practical, and it’s the first time you get to apply what you’ve learned to something concrete.

The total assessment time is 30 minutes. Most people finish each part well inside the allocated time.

Can the exam be taken on the virtual classroom course?

Yes. When IOSH Working Safely is delivered live online (via Microsoft Teams or Zoom), the exam is delivered through the same platform. The multiple-choice section is typically done via an online form; the hazard-spotting exercise uses a shared image on screen. The pass mark, format, and pass rate are identical to the in-person version. Our virtual vs in-company IOSH training guide has more detail on how the two formats compare in practice.

Frequently asked questions

Is the IOSH Working Safely exam hard?

No, by any reasonable measure. It’s pitched at awareness level for delegates with no prior safety training, and the pass rate is typically 95%+ across the industry.

Do I need to revise before the course?

No. Everything you need to pass is covered on the day. Pre-course revision is unnecessary and, if anything, counter-productive — the trainer will teach things in a specific structure that works.

How long is the IOSH Working Safely certificate valid?

Lifetime. There’s no expiry date on the certificate. IOSH recommends a refresher every three years to keep knowledge current, but there’s no legal or contractual expiry.

What’s the difference between the IOSH Working Safely and Managing Safely exams?

Managing Safely is longer — a more substantial multiple-choice paper plus a practical risk-assessment project — and more technically demanding. See our IOSH Working Safely vs Managing Safely comparison for the full breakdown.

Can a delegate with dyslexia or a learning difference get support during the exam?

Yes. Let your training provider know in advance — extra time, coloured overlays, or a reader can usually be arranged. It makes no difference to the certificate.

Will I get the actual exam paper to take away?

No — IOSH keeps the question bank confidential so that the exam stays meaningful. You’ll get your result and feedback on the day, and your certificate shortly afterwards.
