DVSA test guide

How the DVSA driving test works

Plain-English references for instructors: how the test is marked, what the DL25 records, how to run a mock that means something, and how your own Standards Check is scored.

Driving test faults The practical test is marked in three fault types. Knowing exactly where the lines sit helps you judge a pupil against the real standard. The DL25 explained DL25 is the driving test report — the record of every fault on a test. Its structure is the backbone of a good mock. Running a mock test A mock is only useful if it feels and marks like the real thing. Here is how to run one that a pupil learns from. Test readiness Readiness is about consistency without help, not a single good lesson. These are the signals worth trusting. ADI Standards Check Your own check, marked on the same form as ADI Part 3. Here is how the score becomes a grade.

Figures follow published DVSA guidance, last checked 27 August 2026. Check the current DVSA guidance — only a DVSA examiner can give a real result.

Mark a mock the DVSA way

Lesson Diary groups mock-test faults in DL25 order, gives a live pass or fail, and feeds every fault into the pupil’s progress record.
