Administration process

Below is a step-by-step summary of the ISA process.


Register your school online. This is a one-off process to collect general information about your school.


Once your registration is approved, log in to your account and place your order for paper and/or online testing in either September or February.


Once orders are closed, the ISA Team will contact your school with details on how to prepare for testing, including uploading student data and creating test sessions. Paper-testing schools will receive materials via courier prior to the testing window.


Administer the tests during the testing window, following the instructions provided in the Administration Handbook. Paper-testing schools return completed materials to ACER in Australia.


The ISA team will confirm student details are correct at the conclusion of testing. Reports are produced and delivered online to schools in December (for ISA September) or in April (for ISA February).


Invoices are emailed to schools after the release of reports.
