What a CSCS mock test simulates
A CSCS mock test is a full timed simulation of the live CITB Health, Safety and Environment test you will sit at a Pearson VUE centre. It uses the same format as the real exam: 50 multiple-choice questions, 45 minutes, no negative marking, and a 45/50 (90%) pass mark. There is one correct answer per question on most items, with a small number of “select two” questions where both selections must be right to score the mark.
The point of a mock test is not to learn, that is what topic practice is for. The point of a mock test is to verify, under time pressure and without per-question feedback, that you have learned enough. If you cannot consistently hit 45 out of 50 on a mixed-topic mock test at home, you will not pass at the test centre with the additional pressure of an unfamiliar room, an invigilator and a touch-screen interface. Mocks are the dress rehearsal before the live performance.
The three CSCS test versions, Operatives, Specialists, MAP
CITB runs three separate Health, Safety and Environment tests, each targeting a different layer of the construction workforce. All three share the same 50-question, 45-minute, 90% pass mark format since the 2025 standardisation, the difference is in the syllabus weighting and the additional topics that appear at supervisor and manager level.
- Operatives test, covers the sixteen core safety topics. Required for the Green Labourer Card, the Blue Skilled Worker Card and the red trainee cards. This is the most-sat version of the test by some distance, if you are a labourer, groundworker, traffic marshal, tradesperson, demolition operative or apprentice, this is your test. Practise with the free Green Card mock test.
- Specialists test, for specialist trades with a CSCS Gold Card not based on supervision. Same syllabus as Operatives plus some specialist-trade-specific questions. Less commonly sat than the other two.
- Supervisors test, adds CDM 2015 duty-holder roles, leading by example, mental health awareness on site and behavioural safety. Required for the Supervisors Gold Card. Practise with the free Supervisor mock test.
- Managers & Professionals (MAP) test, adds demolition planning, highway works (Chapter 8 traffic management) and the strategic side of leadership. Required for the Black Card or the White Card (chartered professionals). Practise with the free MAP mock test.
If you are not sure which version applies to your card route, the safe default is the Operatives test, it covers the foundation that every other version assumes you know. People applying for the Blue Skilled Worker Card sit Operatives, not Specialists; this is a common point of confusion. See our card types guide if you need help picking.
What to expect on test day at the Pearson VUE centre
The live CITB test is sat at a Pearson VUE test centre, of which there are around 70 across the UK. You will need to bring two forms of photo ID, typically a passport or driving licence plus a utility bill, and arrive 15 minutes early to get through security and complete a digital signature capture. Phones, watches, jackets and bags must go into a locker. You will then be shown to a workstation, given an on-screen tutorial, and the 45-minute clock starts once you click Begin.
The interface is straightforward: one question at a time, four options to choose from, a Next button to advance and a Review button if you want to flag a question and come back to it. There is no audio component for the Operatives test. You can change your answers freely until you submit. The most common test-day mistake is rushing the first ten questions because of nerves, pace yourself at 54 seconds per question, which is comfortable, and the timer becomes a non-issue.
Your result is shown on-screen the moment you finish. There is no waiting list, no marking delay and no resit cooldown, if you fail you can rebook for the next available slot, often the same week. A pass certificate is emailed within 48 hours. Bring that certificate with you when you apply for your CSCS card; the test pass is the gate, the card is the next step.
What to expect on a CSCS mock test at home
Our free mock test mirrors the real test as closely as a browser-based simulation can. The 45-minute timer runs continuously from the moment you start. You answer 50 questions, with the option to flag and return to questions you are unsure about. There is no feedback during the test, wrong answers are not flagged until you submit, which is exactly how the live exam behaves. At the end you see your score, a pass/fail verdict against the 45/50 threshold and a topic-by-topic breakdown showing which areas dropped your marks.
The mock test runs in any modern mobile or desktop browser. You do not need to install an app, sign up or enter any payment details. If you want to save your scores across multiple mock attempts and unlock AI explanations on wrong answers, you can upgrade to Premium from £2.99/week, but the free mock is a faithful enough simulation that most candidates who hit 90%+ on it go on to pass the live test first time.
Five sample CSCS mock test questions and answers
Below are five exam-format questions to give you a feel for the level of specific detail the CITB test expects. In a real mock you would see fifty in this format, with four options each and no per-question feedback until you finish. These five include answers and explanations so you can use them as standalone revision.
Q1. You are working on a scaffold platform 4 metres above the ground. What is the minimum height for the main guardrail under the Work at Height Regulations 2005?
- A. 450 mm
- B. 750 mm
- C. 950 mm ✓
- D. 1100 mm
Why: Main guardrails must be at least 950 mm above the working platform, with an intermediate rail no more than 470 mm below it and a 150 mm toe board to prevent objects falling.
Q2. A diesel forklift has just delivered a pallet to your work area. The driver leaves the engine running while unloading. What should you do?
- A. Nothing, that is the driver's decision
- B. Ask the driver to turn the engine off and report the practice to your supervisor ✓
- C. Move away from the exhaust
- D. Open a window
Why: Diesel engine exhaust is a confirmed Group 1 human carcinogen. Engines must not be left idling unnecessarily, and the issue should be raised with the supervisor so the rule is enforced consistently.
Q3. Which of the following is NOT a duty of an employee under the Health and Safety at Work Act 1974?
- A. Take reasonable care for their own safety
- B. Take reasonable care for the safety of others
- C. Provide safe equipment for colleagues ✓
- D. Co-operate with the employer on health and safety
Why: Providing safe equipment is an employer duty under sections 2-3 of the Act, not an employee duty. Employees must take reasonable care for themselves and others and co-operate with safety measures, but supplying equipment is on the employer.
Q4. A colleague has been struck by a falling object and is bleeding heavily from a leg wound. What is the FIRST action you should take?
- A. Move them to a safer location
- B. Call 999
- C. Make the area safe before approaching ✓
- D. Apply direct pressure to the wound
Why: Always make the area safe first, otherwise you risk becoming a second casualty from the same hazard. Only once the area is safe should you approach, apply direct pressure to the wound and call for help.
Q5. You are about to use a Class 1 (110V) power tool in wet conditions. Which protective device should be in the supply circuit?
- A. A 5 amp fuse
- B. A residual current device (RCD) ✓
- C. A surge protector
- D. A timer switch
Why: An RCD trips the supply in 30 milliseconds if current leaks to earth, including through a person. RCDs are mandatory on site supplies feeding portable electrical equipment, particularly in wet or damp conditions where the risk of earth-fault shock is highest.
Pre-test checklist, the night before
If your live CITB test is tomorrow, these are the six things that matter, in order of how much they affect your chance of passing.
- Two mock tests at 45+/50 in the last 48 hours. If you have not hit the pass mark twice in a row recently, postpone the booking. £23.50 to delay a week beats £23.50 to retake.
- Two forms of photo ID packed. The standard combination is passport or driving licence plus a recent utility bill, council tax bill or bank statement. Pearson VUE will refuse entry without both.
- Test centre location confirmed and journey time padded. Aim to arrive 30 minutes early. Late arrivals are typically turned away with no refund.
- A 15-minute weak-topic review. Skim your three weakest topics from your most recent mock, do not try to learn new material the night before. The aim is to refresh, not to cram.
- Sleep, water and breakfast. A tired brain reads questions wrong. Aim for 7+ hours sleep, eat a proper breakfast, and arrive hydrated.
- Phone, watch, jacket, bag, in the locker. Everything goes in a locker before the exam room. Anything found on your person is grounds for the exam being voided.
