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.

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.
