Candidates are able to defer their ISAT registration once. Any subsequent deferrals will incur a deferral fee of $65 AUD. Candidates can defer to any Window within the 2022 – 2023 testing period.

Candidates must request a deferral via their ACER ISAT account only. To defer your registration, log in to your online account and select the ‘manage’ option on your registration. You will be able to update your registration details.

Deferral requests close:

  • Test Window 1: 18 April 2022 (9pm AEST)
  • Test Window 2: 18 July 2022 (9pm AEST)
  • Test Window 3: 24 October 2022 (9pm AEST)

Once a deferral has been processed, candidates cannot then apply for a refund for their deferred sitting.
