What is the TWC Refresher mock test?
The Temporary Works Coordinator Refresher is a one-day Site Safety Plus course for experienced coordinators who need to renew their certificate, usually every five years. It brings your knowledge up to date with the latest revisions to BS 5975 and current industry guidance, reaffirms the TWC role, and reminds you how to keep a safe, well-documented temporary works process running on site.
This free mock test helps you prepare with confidence. Each attempt gives you 22 questions drawn across the refresher syllabus, from the temporary works register and design-check process through to permits to load and strike. You have 45 minutes and need 78% to pass, so it is an honest rehearsal of the standard the classroom assessment expects before you sit the real thing.

- With roughly two minutes per question, keep a steady pace, flag anything you are unsure of and come back to it rather than stalling on one item.
- Aim comfortably above the 78% pass mark in practice, so you carry a margin of safety into the pressure of the classroom assessment.
- After each test, read the feedback on every question you missed and revisit that part of BS 5975 or your course notes before you retake it.
- Work through all five tests before your course, then repeat them a day or two beforehand to keep the key facts fresh in your mind.

TWC Refresher mock test FAQs
Yes, entirely free. There is no registration, no subscription and no card details required. The platform is funded by a handful of trusted training partners, so you can practise as often as you need without paying a penny.
Each test contains 22 questions covering the breadth of the refresher syllabus, from BS 5975 updates and the design-check process through to permits and lessons learned from past failures.
The pass mark is 78%, which works out at roughly 18 correct answers out of 22. We would encourage you to aim a little higher in practice to build a comfortable buffer.
You get 45 minutes per test, the same time allowance as the official assessment. That is a little under two minutes a question, which is plenty if you keep a steady rhythm.
No. Live CITB questions are confidential and cannot be published anywhere. Ours are written independently to match the official syllabus, wording and difficulty, so the practice feels realistic without copying the real paper.
No, this mock is revision only. To renew your certificate you must attend the official CITB Site Safety Plus TWC Refresher course and pass the assessment delivered by an approved training provider.
Sit a full test under timed conditions, review every question you got wrong, then read around that topic in BS 5975 and your notes. Repeat across the tests until you are scoring consistently well.
Absolutely. There are five separate tests with no overlapping questions, and the answer options are shuffled each time, so you can keep practising without simply memorising where the answers sit.
