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 cycle within the 2021 – 2022 testing period.

Candidates must request a deferral via their ACER ISAT account only.

Deferral requests close:

  • Cycle 3: 26 July 2021 (9pm AEST)
  • Cycle 4: 25 October 2021 (9pm AEST)

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