Turn evidence into useful practice

Look at the skills behind the faults.

Choose a test centre to explore recorded fault categories. These counts can help structure a conversation about observation, control and planning alongside your own lesson feedback.

Understand the count

A single test can record several faults, including more than one type. Counts are not numbers of failed tests or your chance of committing a fault. The attachment does not supply matching test denominators for a fault-rate calculation.

Keep the dates visible

We use explicitly labelled January and February 2026 rows in DVSA’s July 2026 response. Later and unlabelled repeated blocks are excluded. A centre may have only one of these months; missing observations are not zero.

Practise the full syllabus

Use the figures alongside feedback from a qualified instructor. A recorded category does not identify a test route, exact junction or guaranteed manoeuvre. Historical category names are retained, including legacy labels.

Isleworth (Fleming Way): January 2026 and February 2026

Sorted by serious-fault count, then dangerous-fault count. The driving-fault column is a separate severity category.
