What the numbers mean for you
Of the 1,659 car tests taken at Dumbarton between April 2025 and March 2026, 876 ended in a pass. That is better than the 50% average across every centre in the country, by 2.8 percentage points.

A pass rate is not a difficulty score. It measures who passed, not how hard the routes are. Centres serving mostly well-prepared candidates score higher, and a quiet rural centre with few tests can swing several points on a handful of results. Use it to compare options, not to predict your own result.
