The PDC has a dedicated online entry system.
All players must Register their details with the system at this link (existing PDC players are required to do this with the new system to ensure that your details are correct).
Following your registration, you will receive an email to confirm that you are available to enter tournaments, and at this stage you can login to make your entry to the relevant Qualifying School. This verification may take up to 48 hours.
Players should pay particular attention to the entry deadlines for events, as the automated system closes entry at the advertised date/time.
