CSCS Test Topics

Just like every other test, preparation is key. You can use any CSCS mock exam to practice online, but if you don’t understand the key concepts in each topic, you’re essentially setting yourself up for failure. With that in mind, here are the CSCS test revision topics you will need to revise to ensure you pass your test in 2026:

CSCS Test Tips

Passing the CSCS test is straightforward, but most people underestimate how difficult it really is; they often think it’s all common sense. Some questions will be common sense, but most will require you to have done some CSCS test revision – especially for core topics that include fire extinguishers and fire safety procedures. That being said, here are some top tips to help with your CSCS test revision:

• Don’t underestimate the test – As I’ve mentioned above, don’t underestimate the CSCS test. Even though some people might say it’s common sense, it’s not; if it were, there would be a 100% pass rate. Don’t set yourself up for failure; make time and put in the extra effort to do as much CSCS test revision as you can.
• Know your fire extinguishers – Time and time again we receive emails from test candidates who say that they’ve failed because of the fire extinguisher questions. They don’t know exactly which questions they answered incorrectly, but they do know they weren’t confident about them. Always pay extra attention to this section during your revision; don’t just cram it – take the time to actually learn it because it could save your life one day.
• Only revise what you need to know – You should focus your Health Safety and Environment test revision around the topics you need to know. The operatives test consists of 16 core topics, but the official CSCS test revision book covers other specialist activities that may not relate to your test. If you’re taking the Operatives test, you will only need to revise up to section D in the book; focus on these sections and maximise your time and effort here.
• Practice makes perfect – After you’ve completed enough revision, test what you’ve learned with our CSCS mock test here to see if you’re ready. Our practice questions test your knowledge of all the core topics on the CSCS test for operatives.

2026 CSCS Exam Structure

The CSCS test for operatives has 50 multiple-choice questions to complete in 45 minutes, with a pass mark of 45 out of 50 (90%). The questions are divided into 2 main groups: behavioural case study questions and standard multiple-choice questions (core knowledge questions).

• Behavioural case study questions: In this section, you will answer 12 questions. These questions will feature a fictional character going about the daily routine of an on-site worker; as the day progresses, you will be asked different questions about what the character should do when a certain situation arises.
• Core knowledge questions: The remaining 38 questions will come from the core knowledge questions; these questions will be drawn at random from the 16 categories listed below. All the questions will be in a multiple-choice format with a slight variation as to how you interact with them; these are as follows:

Hot spot questions: You answer hot spot questions by selecting the correct spot on an image.

Hot area questions: You answer hot area questions by selecting the correct area on an image.

Drag-and-drop questions: You answer drag-and-drop questions by dragging an answer and dropping it in the correct area for that question.

Standard multiple-choice questions: These are regular multiple-choice questions where you select the correct answer from a list of options; these can also be images.
