Important information - November 2025 exams

We have been made aware of a Windows update (known as 25H2) which is affecting the original Exam4 link that has been distributed to ATT students sitting their exams at the November 2025 exam session.

We will be sending a communication to all ATT students entered for the November 2025 session advising them to remove the existing Exam4 link from their device and replace it with the updated link which can be found on the ATT website.  The email will direct students to where the link is on the website. 

This is because there is a risk that even if the device on which the student intends to take their examination is not currently using the 25H2 update that this will be installed automatically as part of a systems update between now and the date of the examination. If this happens the old link will not work for the student. In this event, the student will need to install the new link to enable them to complete the ATT examination. Therefore, we would advise all students to download and test the new link now.

We are also now able to provide a Mac link for those students wishing to use a Mac.  The Mac link will be available via the original candidate email. 

Ahead of your exam day, you must install, test and practice using Exam4 to ensure that it runs correctly on your device and that you are comfortable with all the Exam4 functionality.

The latest version of Exam4 must be installed for the November 2025 exam session.

November 2025 Exams - Candidate e-mails

The November 2025 ATT candidate emails have been emailed to students registered for the November 2025 exam session.  Please ensure you read the email and the candidate instructions carefully.  You are strongly advised to practice using the practice Exam4 link which you can access via your candidate email.
