Failing ADI Stage 1: resits, waiting times and appeals

Quick answer. A failed Stage 1 is a delay, not a dead end. Attempts are unlimited, but you must wait three complete business days and request a new eligibility number before you can book again. Once you pass, all three stages must be finished within two years of that pass.

A failed Stage 1 is a delay, not a dead end. The rules around re-sitting are specific, though, and two of them routinely cost candidates more time than the wait itself.

How many attempts you get

Current RSA guidance permits unlimited Stage 1 theory-test attempts, subject to the published repeat-booking process. There is no cap that ends the route after a set number of failures.

The real constraint is elsewhere: once you pass, all three stages must be completed within two years of that pass. Attempts before the pass do not consume the window, but they do consume calendar time and fees.

The waiting period

After failing Stage 1 you must wait at least three complete business days before re-sitting. “Complete business days” excludes the day of the test itself and any weekend or public holiday in between, so a Thursday failure does not usually mean a Monday re-sit.

Do you need a new eligibility number to resit?

The step people miss. You must request a new Prometric eligibility number before applying again. The number used for your first attempt does not roll over. Candidates who go straight to the booking site after the waiting period find they cannot book, and then lose several more days sorting it out.

Request the new number as soon as the result is known rather than at the end of the waiting period — the two processes can run in parallel, and there is no advantage in serialising them.

Use the report before you rebook

You receive a report on your performance at the end of the test. Because Stage 1 is marked section by section, that report identifies exactly which section ended the attempt.

Resist the urge to rebook immediately and revise everything again. If the failure was in one section, general revision spreads your effort across four sections you already passed. Work the failing section to a comfortable margin — not to the threshold — and keep the others warm with light mixed practice. Sections and pass marks sets out what each section is really asking for.

Appealing a result

Current RSA guidance says a Stage 1 result appeal must be made within ten days of the exam, through the published Candidate Service Team process.

Ten days is short, and it runs from the exam rather than from the day you decide something went wrong. If you have a genuine concern — a problem with the test environment, or a question you believe was defective — make a note of the specifics on the day while you can still recall them precisely, and start the process early rather than using the full window to decide.

Planning the second attempt

  1. Read the section report before you leave the centre car park.
  2. Request the new eligibility number the same day.
  3. Spend the waiting period on the failing section only.
  4. Re-test that section in isolation until you clear it with margin.
  5. Book once you are consistently above threshold in all five, not on average.

Frequently asked questions

How long do I have to wait to re-sit the ADI theory test?

At least three complete business days after a failed attempt, under current RSA guidance. You must also request a new Prometric eligibility number before applying again.

How many times can you fail ADI Stage 1?

Current RSA guidance permits unlimited attempts, subject to the published repeat-booking process. Each attempt costs time and the published fee, and the two-year window to complete all three stages only starts once you pass.

Can I appeal an ADI Stage 1 result?

Yes. Current RSA guidance says an appeal must be made within ten days of the exam, through the published Candidate Service Team process. The window runs from the exam date, so act early.
