Merthyr Tydfil Theory Test Centre: 41.10% pass rate
DVSA recorded 13,427 car theory tests here in April 2025 to March 2026 and 5,519 passes. The fee is £23 a sitting everywhere in Great Britain, so at this rate a pass takes £55.96 of test fees.
Of the 13,427 car theory tests sat at Merthyr Tydfil in the year to March 2026, 5,519 ended in a pass and 7,908 in a fail. 41.10% is 3.74 points below the 44.84% national figure. That is the 151st highest pass rate of the 165 centres with enough tests to compare, and 15th of 17 in Wales. Merthyr Tydfil is a high-volume centre, working through roughly 1,119 sittings a month.
The theory test fee is £23 at every centre in Great Britain, so what changes from place to place is not the price of one sitting but how many sittings a licence takes. Each pass at Merthyr Tydfil takes 2.43 sittings on average, which is £55.96 of DVSA fees per licence, £4.67 more than the £51.29 national figure. The 7,908 fails at Merthyr Tydfil last year came to £182k in fees paid for tests that had to be taken again, out of £309k taken at this centre in total.
DVSA publishes the split by recorded gender. Women passed at 42.63% here against 39.72%, a difference of 2.91 points, where the national gap is 4.20 points. In fee terms the group with the lower rate spends about £3.95 more per pass at this centre.
Month to month the rate moves about. January 2026 was the strongest month here at 46.0%, April 2025 the weakest at 38.2%, and September 2025 the busiest with 1,252 sittings. A swing of 7.8 points across one year is normal in a sample this size and is not a reason to time a booking.
Across Wales as a whole, DVSA recorded 125,666 car theory tests at 17 centres over the same twelve months, a pass rate of 42.98% and £53.51 of fees per pass. Merthyr Tydfil is below that regional figure by 1.88 points.

The £23 fee, applied to Merthyr Tydfil
The theory test fee does not vary by centre, so this table is the same £23 arithmetic everywhere, run against Merthyr Tydfil's own published pass rate. It describes what theory testing costs the candidates who book here on average. It is not a prediction for one person, and it is not a reason to travel: the question bank and the pass mark are national.
| Measure | Merthyr Tydfil | Wales | Great Britain |
|---|---|---|---|
| Pass rate | 41.10% | 42.98% | 44.84% |
| Sittings per pass | 2.43 | 2.33 | 2.23 |
| DVSA fees per pass | £55.96 | £53.51 | £51.29 |
| On top of one £23 sitting | £32.96 | £30.51 | £28.29 |
| Against the national average | +£4.67 | +£2.22 | £0.00 |
| Fees paid on tests that failed | £181,884 | £1.6m | £37.1m |
Sittings per pass is tests conducted divided by passes, so it counts everyone who sat at this centre, including repeat attempts. Fees per pass is that figure multiplied by the £23 DVSA fee. The fee is ours, from the fee page; the counts are DVSA's.
One retake buys nothing
A second sitting is another full £23. There is no retake discount. The official DVSA revision app is £4.99, so a retake costs about 5 times as much as the thing that would have prevented it.
Share of the learner bill
At Merthyr Tydfil's rate the theory fee works out at 3.8% of the £1,470 minimum cost of learning to drive, alongside lessons at about £30 an hour on this site's Wales band. See the full budget.
The two-year clock
A theory pass lasts 2 years. Miss that window before the practical and the £23 is due again. Retakes also need 3 clear working days between attempts, so a fail costs time as well as money.
