CSCS Practice Test

Failed Your CSCS Test? Retake Rules & Next Steps

What to do after a failed CSCS test: read your score report to see where you dropped marks, drill only those topics and read every explanation, sit full timed mocks until you clear 45 out of 50 several times running, then rebook. 23.50 pounds per resit, no limit on attempts, free to practise here. CITB does not publish a waiting period before a resit, so check the earliest slot when you rebook.

Failing is not the end of anything. There is no limit on attempts — you rebook, you pay again, you sit it again. The only real cost is £23.50 and the time. Here is how to make the second attempt the last one.

Use your score report — it tells you where you went wrong

When you finish, you get a score report at the test centre. If you failed, it shows the areas where you dropped marks. That is the single most useful revision document you will get, so do not lose it. You can also request a more detailed report from CITB by emailing their testing services feedback address.

How soon can you retake it?

There is no limit on the number of attempts. On the waiting period, be careful with what you read elsewhere: third-party revision sites variously quote 24 hours, 48 hours and three working days, and we could not find a definitive figure published on citb.co.uk. Check the earliest available slot when you rebook through Pearson VUE rather than relying on a number from a revision site — including this one.

In practice, the more useful question is not how soon you can retake, but whether you are ready. Rebooking for tomorrow and failing again costs another £23.50.

What it costs to retake

  • £23.50 per attempt — the full fee applies every time.
  • Rescheduling an existing booking is free online 72+ hours ahead, or £5 by phone.
  • Cancelling online 72+ hours ahead is a full refund; by phone it carries a £10 admin fee. Inside 72 hours there is no refund.

A four-step plan before you rebook

  1. Read your score report and note the weak areas.
  2. Drill exactly those topics in the topic question banks — read every explanation, including on questions you got right.
  3. Sit full timed 50-question mocks until you clear 45/50 several times running.
  4. Then rebook.

Before you rebook, it is worth knowing exactly what you are up against: the CSCS test pass mark allows five wrong answers out of 50 questions in 45 minutes, which is why most people who fail fail narrowly. For the exam in full, read what the CITB HS&E test is.
