Under strict DVSA regulations, Trainee Driving Instructors (PDIs) have just 2 years after passing ADI Part 1 and a maximum of 3 attempts to pass Part 2 and Part 3. Here is how to secure senior examiner cancellations fast.

1. Why ADI Part 2 and Part 3 Examiner Slots Are 5× Scarcer Than Learner Tests

Unlike standard Category B learner tests, ADI Part 2 (Test of Driving Ability) and ADI Part 3 (Test of Instructional Ability) can only be conducted by Senior DVSA Driving Examiners. When a PDI fails or needs to reschedule, waiting 16+ weeks can push you dangerously close to your mandatory 2-year ADI Part 1 expiry date or your 6-month Trainee Licence deadline.

Our Pro & Priority Tier (discounted from RRP £24.99 to £14.99 one-off) is engineered specifically for PDIs and Green-Badge ADIs.

  • Supports your 6-digit ADI Personal Reference Number (PRN).
  • Supports your 9-digit ADI Part 1 Theory Pass Certificate Number for priority qualifying-window verification.
  • Calls your UK mobile (+44) aloud while you are out teaching on a pink trainee licence or green badge.

2. Earn £5.00 Commission Per Referred Learner Pupil

Every registered ADI and PDI on our platform also receives a free 5-digit Instructor Referral Code. Whenever one of your learner pupils activates a £14.99 pass using your code or link, £5.00 commission is automatically credited to your ADI Partner Portal for UK BACS or PayPal payout.

💡 Double Benefit for Driving Schools

Not only do you earn £5.00 per referred pupil, your pupils also pass weeks earlier - freeing up prime weekly lesson slots in your tuition car for new incoming students.

Frequently Asked Questions

Q: How much is the ADI Partner referral commission per pupil?

Every verified pupil who activates a £14.99 pass using your 5-digit ADI referral code earns you £5.00 commission, paid out to your UK bank account or PayPal.
