How Many People Fail the CSCS Exam? What to Expect on the Day

20 January 2026

In our line of work, we get a lot of feedback and questions from people starting their job in construction. Most are nervous about one thing: the exam.

For many people, it’s been a long time since they were last in a classroom. So the idea of a health and safety test can feel overwhelming. You might be thinking:

  • “What if I fail?”
  • “How much do I actually need to study?”

Here’s the truth: the CSCS Green Card process isn’t designed to trip you up — it’s designed to keep you safe.

At COSAC, we built our Safe2Site Health and Safety Awareness Course specifically for people who don’t enjoy traditional exams. The learning is flexible, practical, and completed in your own time.

Why our course has such a high pass rate

Pace your own learning

There’s no classroom pressure and no one watching over your shoulder. You can learn wherever you like and rewatch the videos as many times as you need.

Easy-to-understand wording

We break health and safety rules down into plain English. No jargon. Just clear, common-sense explanations that actually stick.

Practice really does make perfect

Each section includes mock questions, so you know exactly what the real exam will feel like before you sit it.

How to Prepare for the Exam

Preparation is the key to passing. Many candidates start with Safe2Site online CSCS training, which includes practice tests that closely mirror the real exam. These mock tests help you understand the question style, manage your time, and build confidence before exam day.

If you’re moving into a supervisory role, Safe2Site Supervision Training gives you the knowledge needed to manage teams safely and confidently on site.

For the most complete option, the Complete Online CSCS Green Card Package – Safe2Site Premium combines all required training with multiple practice tests in one place.

You can also take the CSCS Green Card Mock Test for extra preparation before the real exam.

How Hard is the CSCS Exam?

The CSCS exam is very manageable with the right preparation. It’s a multiple-choice, computer-based test designed to check your understanding of site safety — not to catch you out.

Most candidates pass on their first attempt, especially when they’ve used Safe2Site courses and mock tests. Knowing the format and key topics in advance makes the exam feel familiar and straightforward.

What Happens on Exam Day

Arriving a little early helps keep nerves in check. You’ll check in, show your ID, and be seated at a computer. The instructions are clear and easy to follow.

Exam Format

The test is entirely multiple choice. You’ll have plenty of time to read each question carefully and review your answers before submitting. Most people find it far less intimidating than they expected — especially after practising online.

How Many People Fail the CSCS Exam?

Very few people fail the CSCS exam when they prepare properly.

Most failures happen when candidates try to go straight into the test without revision. When learners complete Safe2Site training and mock tests, they walk in confident and ready — which is why 98% of COSAC students pass.

After the Exam

Results are usually available quickly, helping you move forward with your CSCS card application without unnecessary delays. Good preparation means less stress and faster progress on site.
