A pass rate is a record of tests, not a forecast for you
The pass rate is passes divided by tests in a defined group and period. The same person can take more than one test. A centre’s candidate mix, traffic, test volumes and teaching patterns can differ from another centre’s.
Choosing a centre because it has a higher published pass rate does not establish that it will be easier for you. Familiarity with safe driving in varied conditions matters more than memorising a location.
Two waiting measures answer different questions
The forward-availability measure reports how far ahead a defined proportion of weekly appointments becomes available. The median completed wait describes people who actually took a test in that month, including changes to bookings.
Neither measure is an earliest available appointment. The website shows the source period beside each value and keeps the two measures separately named.
Missing data has a meaning
Suppressed, unavailable, not applicable and no-tests values are kept as missing states. They are never silently converted to zero. Some centre outcomes are withheld where the publication’s disclosure rules apply.
Annual all-car results, automatic-only results and quarterly NI figures are not interchangeable. The comparison tool labels the period and transmission for every statistic.
