“The DVSA impose timescales during the qualificaiton process. Once you’ve passed your Part 1 test, you have two years until that theory test pass expires. During those two years, you must pass the Part 2 and Part 3 tests in order to become an Approved Driving Instructor.
If you do not complete the tests in this period, you will have to restart the process from the Part 1 test.
For this reason, we have course timeframes in place to ensure you work through Parts 1, 2 & 3 in a timely manner to ensure your qualification.”
