Post-16 pupils who need transport from September are being urged to apply from today.
The process to generate and pay for passes opens at half nine this morning.
Passes cost £600 for the whole school year and applicants will be asked to make a deposit when they apply.
Some pupils may qualify for a discounted price and should refer to the guidance notes on the website for details.
