Roughly one in three candidates fails at least one of the SIA Door Supervisor multiple-choice papers on first sitting. Almost every one of those failures is avoidable. The qualification doesn't test you on obscure case law or physical strength — it tests whether you've understood the workbook and can apply it calmly under timed conditions. This guide gives you a two-week plan for a typical evening or weekend learner who already has the course booked.
Two weeks before your course
Most training providers send you the SIA workbook before classroom week begins. Read Units 1, 2 and 3 straight through — yes, all of it — before you arrive. Spend roughly 6–8 hours over the fortnight, highlighting anything you don't understand. Don't try to memorise yet; the goal is familiarity. You'll retain twice as much in class because you already have a mental scaffold.
During classroom week
Sit at the front, ask every question you have, and write notes in your own words rather than copying the slides. Trainers see thousands of candidates a year and know exactly which questions trip people up — pay extra attention whenever they say "this comes up in the exam". After each day, spend 30 minutes going through that day's quick-check questions in the workbook.
The 48 hours before the exam
Stop reading the workbook and switch to active practice. Take a full mock under timed conditions for each unit you have left to sit. Mark it ruthlessly, read every explanation — including the questions you got right by guessing — and write down any rules you didn't actually know. Do this twice and you'll usually gain 5–10 marks on the real paper.

- Emergency procedures — fire safety, evacuation, terror response (ACT principles).
- Equality and diversity — the Equality Act 2010 and protected characteristics.
On exam day
Arrive 20 minutes early with a valid photo ID — usually a passport or driving licence. Read every question twice before answering. Use the flag function to mark anything you're unsure of and come back to it. Never leave a blank — there is no negative marking, so a guess is always better than a zero.
What to do if you fail a unit
You can normally re-sit a failed paper within 28 days for £25–£45. Do it as soon as possible while the material is still fresh. Use the time to drill the unit you failed using free mocks, not to re-read the whole workbook.
After you pass
Apply for your SIA licence the day your certificate arrives. Approval typically takes 5–10 working days if your DBS check is clean. While you wait, brush up on venue-specific topics with our other Security & Door Supervision practice mocks.

Quick study plan
If you only have a fortnight to prepare, split your time into three blocks. Spend the first few days reading any official handbook or syllabus straight through — don't try to memorise yet, the goal is familiarity. Move on to topic-by-topic revision, focusing on the areas you found least intuitive on the first read. In the final week, switch to timed mock tests under exam conditions; mark every paper ruthlessly and read every explanation, including for questions you got right by guessing. Most candidates improve by 8–12 marks between their first and third mock simply by closing knowledge gaps this way.
Common myths to ignore
Three myths trip up more candidates than any single topic. The first is that "if I sit enough mocks, I'll spot the real questions on test day" — modern UK exam banks contain hundreds of items and the question you see on the day will probably be brand new to you. The second is that you can cram the night before; most assessments reward calm focus more than recent recall, and tired candidates make basic mistakes. The third is that the pass mark is the only thing that matters: aiming for a comfortable buffer of 5–10 marks above the threshold is the single best insurance against an unlucky paper.
What to do on test day
Plan to arrive 15–20 minutes early with valid photo ID — usually a UK driving licence or passport — and any booking confirmation you've been emailed. Eat something light beforehand, drink water but not so much that you'll need a comfort break mid-paper, and silence your phone before you walk through the door. Read every question twice, flag anything you're unsure of, and never leave a blank — there's no negative marking on the assessments most readers of this site sit, so a considered guess is always better than no answer at all.
