Once you have received your Disclosure and Barring Service (DBS) number you may now register as a PDI (Potential Driving Instructor).


To do this, you can apply by post or online.

  • your driving licence number
  • your Disclosure and Barring Service (DBS) check and the date it was produced (unless you’ve been told not to get one yet)
  • details of any motoring or non-motoring offences, and disqualifications from driving or of any court cases being brought against you


The DVSA will write to confirm your registration and PRN.

This whole process can take about 4-6 weeks so we advise starting your studies ASAP and complete Part 1 whilst this process is completed.

You now have your DVSA PRN (personal reference number). You may now book your 1st test when ready.
