CSCS Mock Test — Free Practice

What is the CSCS test?

The CSCS Health, Safety and Environment (HS&E) Test is the touch-screen exam every construction worker in the UK has to pass before applying for almost any CSCS card. It is delivered on behalf of the Construction Skills Certification Scheme by CITB at testing centres across the country, and it exists for one reason: to make sure that anybody who steps onto a UK construction site understands the basic rules of working safely. The test focuses heavily on hazard awareness, site-specific risks and what to do when something goes wrong, rather than trade-specific knowledge — the trade competence comes from your NVQ or qualifications. There is one version of the test for operatives, one for specialists and one for supervisors and managers, and each version has the same demanding pass mark.

What's in the CSCS test?

The CSCS HS&E test draws its questions from the official "Health, Safety and Environment Test for Operatives and Specialists" revision materials. The questions are grouped into clear knowledge areas so you can prioritise revision:

• General responsibilities — the law (HASAWA 1974, CDM 2015), accident reporting (RIDDOR), permits and why your behaviour on site matters.
• Health and welfare — health surveillance, occupational health risks, mental wellbeing, manual handling, vibration, noise and dust.
• High-risk activities — working at height, excavations, confined spaces, lifting operations, fire and emergencies.
• Environment — protecting waterways and wildlife, waste segregation, dealing with spills, environmental incident reporting.
• Specialist activities (specialist tests only) — additional questions specific to plant, demolition, highway works, lifts, tunnelling and others.

How the CSCS test is scored

The Operative HS&E test gives you 50 questions and 45 minutes. You need 47 correct out of 50 to pass — a pass mark of 94%. That sounds intimidating, but the questions are not deliberately tricky: most are common-sense health and safety once you have learned the official terminology. The Supervisor and Manager tests use the same 50 main questions but add behavioural case studies that test how you would respond to site situations as someone in charge. There is no negative marking, the questions are presented in a fixed order, and you get your result immediately at the end. If you fail, you can rebook straight away and resit at any approved testing centre.

How to use this CSCS mock test

1. Take a baseline test in practice mode. Don't worry about the score — you are mapping your weakest topics.
2. Drill the weak knowledge areas. Most failed attempts come down to two or three topics, usually working at height, asbestos and electricity.
3. Sit a full timed mock. 50 questions, 45 minutes, no pausing. This is where you learn to manage the clock without panicking.
4. Review every wrong answer. The official explanation usually contains the exact phrasing the real test uses, so reading it carefully sticks the answer in your memory.

Tips for passing CSCS first time

• Watch out for "first aid" answers. The correct CSCS answer is almost always to make the area safe first, then call someone — not to wade in and help directly.
• Default to "stop work and report". If the scenario describes anything unsafe, the right answer is usually to stop, isolate and tell your supervisor.
• Know your PPE order. PPE is the last line of defence, not the first — questions often test whether you know to eliminate hazards before relying on PPE.
• Don't overthink the behavioural questions.Choose the option that protects people, follows the law and reports the issue.
• Practise on a touchscreen if you can. The real test uses a touch-screen interface, and that small difference can throw nervous candidates.

After you pass: getting your CSCS card

Passing the HS&E test is the gateway, not the destination. With a valid HS&E pass in hand, you apply for the right CSCS card for your role — Labourer, Skilled Worker, Specialist, Supervisor or Manager — through the official CSCS portal. Each card requires its own evidence: an NVQ at the right level for skilled cards, a CITB SSSTS or SMSTS for supervisors and managers. Cards are usually valid for five years. Treat the HS&E test as the standard you maintain across your career, not a one-off — it is renewed every time your card is, and the syllabus updates as the construction industry changes.
