The CITB Health, Safety and Environment Test — most people just call it the CSCS test — has a roughly 50% first-time pass rate among unprepared candidates. The test isn’t unusually hard. People walk in cold, with no sense of the question format, the timing, or the behavioural-case scenarios CITB uses.

The fix is simple. Take a CSCS mock exams online before you sit the real one. This page gives you a free CSCS mock test with sample questions and answers, explains the real exam structure, and tells you the pass mark you need.

How the real CSCS test works

The official name is the CITB HS&E Test (Health, Safety and Environment Test), run by the Construction Industry Training Board. Different versions exist for different roles. Anyone applying for a CSCS Green Card sits the Operatives version — the HS&E test for operatives.

The facts you need before you book:

The headline figure that catches most people out is the CSCS pass mark: 47 out of 50. You can only get three wrong. No margin for guessing.

Within those 50 questions you face two question types:

• Knowledge questions — straightforward multiple choice on hazards, safety standards, regulations, PPE, signs, and safe practices.
• Behavioural case studies — short scenarios that test how you’d react on site. These trip up unprepared candidates, because more than one answer can look “technically correct” and you must pick the safest.

Why a CSCS mock test is the best preparation tool

Revision books, apps, classroom courses, and YouTube videos all have their place. A CSCS mock exam — taken under proper conditions — does something none of them can. In 45 minutes it shows you exactly where you stand.

Score 49/50 on a mock? Book the real test tomorrow. Score 32/50? You’ve just saved yourself the £25 booking fee plus a wasted afternoon — go back and study the topics you got wrong. Either way, the mock is the most efficient diagnostic tool you have.

A good CSCS mock test for operatives should:

• Use the same 50-question, 45-minute format as the real exam
• Cover the topic areas CITB tests — accident reporting, health and welfare, manual handling, working at height, PPE, fire and emergencies, electrical safety, hazardous substances, environment and waste
• Include behavioural case study questions, not just knowledge ones
• Show the right answer with an explanation when you get one wrong
• Be free to take repeatedly so you can practise until you consistently score above 47/50

Our free online CSCS test practice does each of those. No signup, no payment, no email harvesting — open it and start.

5 sample CSCS mock exam questions (with answers)

Five representative practice questions covering the main topic areas. Try to answer each before you look at the answer below. These reflect the style and difficulty of the real CITB Operatives Test but are not copies of CITB’s official questions.

Question 1 — General responsibility (knowledge)

Who has the legal duty to provide a safe place of work on a UK construction site?

1. The principal contractor only
2. The employer and every worker, each within their role
3. The Health and Safety Executive
4. The site’s main client

Question 2 — Working at height (behavioural case study)

You’re asked to work on a flat roof to clear some debris. Your supervisor hands you the task and walks off. No edge protection is in place and no harness is available. What should you do?

1. Get on with the job — it’s only a small amount of debris
2. Stay back from the edge and work as quickly as possible
3. Stop, refuse to start, and tell your supervisor it’s not safe to begin
4. Borrow a harness from another team and crack on

Question 3 — Manual handling (knowledge)

Before lifting a heavy load, what should you check first?

1. Your back posture
2. The weight of the load and whether you can manage it safely
3. Whether anyone is watching
4. The time of day

Question 4 — Asbestos (knowledge)

You’re stripping out an old commercial building and uncover what looks like asbestos insulation board. What do you do?

1. Carry on carefully — it’s probably fine if you don’t break it
2. Stop work immediately, leave the area, and report it to your supervisor
3. Remove it yourself wearing a dust mask
4. Wet it down to keep dust low and continue

Question 5 — PPE (behavioural case study)

You arrive on site and realise you’ve left your safety boots at home. You’re wearing trainers. Your boots are an hour’s drive away. What’s the right thing to do?

1. Borrow boots from someone in the welfare cabin
2. Work in trainers — it’s only one day
3. Tell your supervisor you can’t work today and explain why
4. Buy a cheap pair from the nearest shop and wear those

Got 4 or 5 right? You’re in a good place — go and take a full 50-question CSCS mock exam next. Got 3 or fewer? Don’t book the real test yet. Spend a few hours on the topic areas you struggled with, then come back and try again.

What topics does the CSCS mock test cover?

The CITB HS&E test for operatives pulls questions from these topic areas, and a good CSCS card mock test mirrors the same balance:

• General responsibilities — UK health and safety law, duties of workers and employers, accident reporting, signs and signals
• Health and welfare — drugs and alcohol, mental health, noise, vibration, hand-arm vibration syndrome
• Hazardous substances — asbestos awareness, COSHH basics, dust, fumes
• Manual handling — lifting techniques, load assessment, mechanical aids
• Working at height — ladders, scaffolding, fall arrest, edge protection
• Personal Protective Equipment — what to wear, when, and why
• Fire and emergencies — fire prevention, extinguishers, evacuation procedures
• Electrical safety — buried cables, overhead lines, portable tools
• Site transport and lifting operations — banksman duties, lifting plans
• Environment — waste, pollution, working near water

Unfamiliar with any of those topic areas? Our online Level 1 Health and Safety in a Construction Environment course covers each in plain English with the exam built in. The course suits any entry level worker on UK sites.

How many CSCS mock tests should you do before booking?

Honest answer: as many as it takes to consistently score 47 or higher. Most candidates need three to five attempts before they consistently sit in the pass zone. Don’t book the real test on the back of one good practice score — that’s a £25 gamble. Book once you’ve passed three mocks in a row.

A useful pattern:

1. First mock — diagnostic. Take it cold. See where you stand. Don’t worry about the score; identify weak topic areas.
2. Study session. Spend 1–2 hours on whatever you got wrong.
3. Second mock — same conditions. Check whether the score improved.
4. Repeat until you score 47+ consistently.
5. Book the real test.

Same revision pattern works for any exam — most candidates skip it and pay the price.

CSCS mock test for operatives vs. supervisors vs. managers

Be careful which mock test you take. CITB runs three different versions of the safety and environment HS&E test:

• Operatives — for Green Card applicants, general labourers, and most trade workers
• Specialist — for specific trades (demolition, plumbing, supply chain, etc.)
• Managers and Professionals — for site supervisors and white-collar construction professionals

A CSCS green card mock test should be the Operatives version. Taking the wrong mock test gives a false sense of preparedness — the questions are weighted differently and the scenarios pitch at a different level. Our free CSCS mock test is the Operatives version unless you select otherwise.

What happens after you pass the real test?

Passing the CITB HS&E Operatives Test is one of two requirements for a CSCS Green Card. The other is completing a Level 1 Award in Health and Safety in a Construction Environment — a regulated qualification that proves you’ve actually had the training, not just memorised the answers.

Both can be done in a single day. Our CSCS Green Card Course + Exam package bundles the Level 1 course, the exam, and a same-day certificate at £119.99. We’ll help you book your CITB test through our test booking service too.

Frequently asked questions

Is the CSCS mock test free?

Yes. Our online CSCS mock test is completely free, with no signup or payment required. Take it as many times as you need.

How many questions are in the CSCS test?

The real CITB HS&E test for operatives has 50 questions, taken in 45 minutes, with a pass mark of 47 out of 50 (94%). Our mock test mirrors the same format.

What’s the difference between a CSCS mock test and a CITB mock test?

Most people use the names interchangeably. The official test is run by CITB. “CSCS mock test” usually refers to practice for that test, because passing it is one requirement for a CSCS card.

How accurate are CSCS mock tests compared to the real exam?

A good mock test follows the same 50-question, 45-minute format with the same topic balance and a mix of knowledge and behavioural questions. It won’t use the real CITB questions (those are copyrighted) but it reflects the same difficulty and style.

What’s a passing score on the CSCS mock test?

Aim for 47 out of 50 or higher — the same as the real test pass mark. Anything less and you’re not ready to book the real exam.

Can I take the CSCS mock test on my phone?

Yes. Our free CSCS mock test works on any device with a browser — phone, tablet, or laptop.

Do I have to pass the CSCS mock test to get a Green Card?

No, the mock test isn’t required — it’s a free practice tool. To get a CSCS Green Card you need to pass the real CITB HS&E Operatives Test and complete a Level 1 Health and Safety in a Construction Environment course.

How many times can I take the CSCS mock test?

As many times as you want. No limit, no waiting period, no charge. Most people take 3–5 mocks before booking the real test.
