CSCS Practice Test

CSCS Test Revision Plan

·

This is a 14-day CSCS revision plan for the CITB Health, Safety and Environment (HS&E) test, the exam UK construction workers pass to get a CSCS card. It uses the free topic banks and timed mocks on this site, most days take an hour or so, and it ends with a clear rule for when to book.

The real test is 50 questions in 45 minutes, and you need 45 out of 50 to pass. That leaves room for five mistakes, so the plan is built around finding your weak topics early rather than sitting mock after mock until the score looks acceptable.

The short version

Measure first with a free CSCS practice test, revise your weakest topics first, drill your wrong answers, then return to the clock. Book when the lowest of your last three timed mock scores is 47 out of 50 or better.

A CITB mock test and a CSCS mock test are the same thing: CITB writes the exam and CSCS issues the card. Whichever name your employer uses, the timed paper in this plan is our CSCS mock test for Operatives, free and with no sign-up.

Your 14-day CSCS revision timetable

  1. Day 1

    Sit a timed mock, cold

    Take the full 50 questions in 45 minutes before you revise anything, and accept whatever score it gives you. Then open Score by topic on the results screen and write down every topic that cost you a mark, worst first. That list is your running order for the next stage.

  2. Days 2 to 10

    Two topic banks a day, weakest first

    Start with the topics on your Day 1 list, then work through the rest. Each topic page runs a 20-question practice quiz and shows every answer with its explanation at the end. Every quiz draws a fresh 20, so do two or three rounds on a weak topic, and finish each one: wrong answers only reach your missed questions when you see the results.

  3. Day 11

    Second timed mock

    Same conditions as Day 1. Every mock draws a fresh 50 from our 2,575 questions, so this is not the paper you sat before. Compare Score by topic with Day 1: the topics that have not moved are tomorrow's work.

  4. Day 12

    Drill the questions you got wrong

    Open your account and start the missed questions drill: the questions you got wrong, which drop off once you answer them correctly. A free account drills your latest test, a pass every test. Then take another practice quiz on any topic still costing you marks.

  5. Day 13

    Third timed mock

    The full paper against the full 45 minutes. Read the review the same day, wrong answers first.

  6. Day 14

    Fourth timed mock, then decide

    Take the lowest of your last three mock scores and check it against the table further down. If it is 47 or better, book the test. If not, repeat the last three days until it is.

Test booked for sooner than 14 days away? Keep every timed mock and cut the topic stage down to the banks your Day 1 mock said you need. Revising around shifts? Do one day of the plan every other day and it takes four weeks instead.

The 18 topics to work through

CITB publishes five core knowledge areas for the Operatives test: working environment, occupational health, safety, high risk activities, and specialist. Five headings is the right map for the exam and the wrong unit for revision, because “occupational health” alone covers dust, noise, vibration, manual handling and welfare. We split the same syllabus into 21 narrower topics, each small enough to finish in one sitting. Those 21are our split, not CITB's labels.

These 18 are the core of the plan. Tick them off in the order your Day 1 mock gave you, not top to bottom:

The other 3 are labelled for other versions of the test: Leadership & Management (MAP), Demolition (Specialist) and Highway Works (Specialist). If you are sitting the Operatives test, leave them until the core 18 are done. All 21 sit together on the CSCS test questions and answers page.

How to use the answer explanations

The score tells you where to look. The explanations are where the learning actually happens.

  • Read it even when you were right. A lucky guess scores the same as knowing the answer, and it will not survive the real test asking the same thing a different way. CITB says questions in the test can be worded differently from its revision materials while the meaning stays the same.
  • Say the reason back before you move on. If you cannot explain in one sentence why the right answer is right, you have not learned it yet, whatever the score says.
  • After a timed mock, read the wrong ones first. The results screen lists all 50 questions with your answer, the correct answer and the explanation. Work through the ones marked wrong, then any you know you guessed.

How to sit a timed mock

  • In one go, against the full 45 minutes, somewhere you will not be interrupted and with nothing to look answers up in. A mock taken in pieces with a search engine open measures nothing.
  • Answer every question. Flag the ones you are unsure of and use the numbered question navigator to go back to them before you finish.
  • Leave at least a day between mocks, and do the revision in between. A mock tells you where you are. It does not move you anywhere.

What score to aim for before you book

The CSCS test pass mark is 45 out of 50, so the real test allows five wrong answers and no more. Aim higher than that on our mocks. Our questions are written by us, not taken from CITB, and the real test will be a different 50, so two spare marks cover the questions you have never seen. Judge yourself on the lowest of your last three timed scores, not the best.

Lowest of your last three mocksWhat to do next
47 to 50Ready, with two or more marks to spare. Book the test.
45 or 46At the pass mark with nothing spare. One more wrong-answer drill and another mock before you book.
40 to 44One or two topics are still costing you. Redo those topic banks, then sit another mock.
Under 40Gaps across several topics. Go back to the topic stage (Days 2 to 10) before sitting more mocks.

Five ways revision goes wrong

Sitting mock after mock

A mock measures, it does not teach. Back-to-back mocks with no revision in between mostly re-test what you already know, and part of any rise is familiarity with questions you have seen before. Revise between mocks, as the timetable does.

Revising the interesting topics

Working at height and electrical safety feel like real construction, so they get the attention. Health and welfare, environmental duties and reporting feel like paperwork, and they carry marks worth exactly the same.

Skimming the multi-answer questions

You only score when every correct option is selected, so a half-right answer scores the same as a wrong one. In a test that allows five mistakes, two careless multi-answer questions is most of your margin gone.

Answering how site actually works

Questions ask what should happen on a compliant site, not what you have seen done. If your honest answer and the by-the-book answer differ, the test wants the book.

Leaving anything blank

Only correct answers count and there is no penalty for a wrong guess. Eliminate what is obviously wrong and pick from the rest. A blank is a guaranteed nil.

Do you need the official book or app?

Not to pass. The free mocks and topic banks cover the knowledge. CITB publishes GT100, its official revision publication for the Operatives and Specialist tests, which CITB states contains all of the content covered in the test, in question-and-answer form. It is worth buying if you revise better from a book. CITB's own app is worth it if you want to rehearse the on-screen question formats that no web mock reproduces.

We have broken both down: the CSCS revision book page covers which GT100 sections your test needs and whether there is a free PDF (there is not), and the CSCS revision app page covers CITB's apps, what they cost, and why most “CSCS flashcards” in the app stores are for a different exam. We have no financial reason to steer you either way: see our affiliate disclosure.

When you are ready to book

Read how to book the CSCS test, then what happens on CSCS test day and what the CSCS touch screen test is like, so nothing on the day is a surprise. Booking early is the expensive mistake: if it does not go to plan, the retake rules mean paying the full £23.50 again.
