  • By submitting this enquiry you are giving your consent to allow RED to contact you to discuss our instructor training course and to send you relevant information about any of its driver training courses and driving related career opportunities via email and SMS. We will hold your data for this purpose for a period of up to 3 years. We will not use your data for any other purpose.

Taking the ADI Part 3 test

  • On the day of your test, make sure to arrive at least 10 minutes early so that you have time to relax and calm your nerves. Remember, the examiner is there to help you succeed—not fail!
  • Once you begin, firstly you’ll need to give your examiner a run-through of your lesson plan. Next up is to introduce them to your pupil and explain the purpose of the lesson to the pupil, noting that they’re not under examination, it’s you.
  • Next up is conducting the lesson, try and think of it as just another lesson with a pupil. But it is worth knowing what you’ll be marked on and keep those areas at the front of mind.

What happens after the exam?

  • Once the lesson is finished, you’ll give your pupil their feedback before getting your result and any observations from the examiner.
  • Along the same lines as the ADI Part 2, you have three attempts at passing but failing all 3 will lead to you having to restart your ADI, so make sure you’re confident in your ability before taking it!

Pete Chiston had to say “The fast track training was very intense and a lot to take in over three days however the follow up support from my in car trainer David was great and tailored to meet my very hands on approach to learning, this in combination with the office support has meant that the process although at points very challenging was still a positive overall experience.”

Preparing for the ADI Part 3 test

  • The best way to prepare for Part 3 is to get as much experience teaching real pupils as possible. This will give you the opportunity to put into practice all the theory you’ve learned in Parts 1 and 2, as well as giving you a chance to get used to being in the driver’s seat when teaching.

Learning with RED

  • When learning with RED, you’ll be given the option to join RED as a potential driving instructor (PDI) and begin giving actual lessons. This is an extremely effective way of honing your skills in instructional ability ahead of your part three test. It also means that you start to make a living as a driving instructor.
  • Your trainee licence is valid for six months, and you will continue to receive 20 hours of additional training, most of which is in-car on a one-to-one basis from a RED trainer prior to your part three test. On passing the test you can apply to be added to the DVSA register of approved driving instructors. The majority of trainees take this route.

When you feel like you’re ready, it’s time to book your test. You can do this by calling the DVSA (Driver and Vehicle Standards Agency). Once your test is booked, make sure to do a mock lesson with an experienced instructor trainer so that you know what to expect on test day.
