We have not found a county-by-county pass rate for the Irish theory test in any official source we have read, so this page does not rank counties. The format and the pass mark are set by test category, not by location: the car test has 40 questions in 45 minutes and you need 35 correct, whichever centre you sit it in. Below is what is published, and the official test centres in each county.
What Is Published and What Is Not
The official Driver Theory Test FAQs publish the number of questions, the time allowed and the pass mark for each category. They say the questions are selected randomly from the question bank. They do not give results by county or by centre.
Our theory test results page shows the yearly totals the RSA has published and explains their limits. We removed the county table that used to be on this page because we could not trace its figures to an official source.

Does It Matter Where You Sit the Test?
Not for the test itself. The number of questions, the time limit and the pass mark come from the test category. What does differ between centres is the appointment times they have, so compare two or three centres on theorytest.ie before you pay.
Pick the centre you can reach comfortably 30 minutes before your test time. That is the official advice, and if you are late or arrive without the required ID you will not be allowed to test and you lose the fee.
What Decides Your Result
Your preparation does. Five mistakes is all the pass mark allows, and the questions are picked at random, so every topic counts.
- Take the free 10-question test. It needs no account.
- Work through each topic and review every mistake.
- Sit timed 40-question mock tests until you score 35 or more each time.
- Read the study guides for the rules you keep getting wrong.
A practice score shows how well you have prepared. It is not a prediction of your official result.
If you do not pass, you can book again. There is no limit on the number of attempts, the car test fee is €45 each time, and the official advice is to wait at least 3 complete business days before you re-sit. You can choose a different centre for the next attempt if its appointment times suit you better.
