@gjjude . Hi.
PTE Academic Score Report is valid for Immigration Purposes in Australia for 3 years, even though on your actual PTE score report you can see it only shows 2 years. I know it is confusing. But it is how it is.
At the request of the Department of Home Affairs, the PTE Academic internal operations team have been working to find a solution to extend the period that test takers can view and assign their scores.
From 29th October 2019 PTE Academic test takers will be able to view and assign their test scores for up to 3 years from their test date.
If a test taker took their test more than 2 years ago and cannot provide their registration ID or Score Report Code for their application, the Department has the capacity to contact PTE Academic's support team to have the result manually verified.
To sum up briefly, for Immigration purposes in Australia, your PTE score report is valid for 3 years. Don’t worry if it only shows on the actual score report only 2 years.
Goodluck sa application!
