Student Username Change

Posted On Monday January 16, 2023

In support of Thames Valley District School Board’s (TVDSB) ongoing commitment to protect the safety and privacy of students, usernames to access online platforms will be changed on Tuesday, January 17, 2023.

In an effort to improve the cyber security of student accounts, the previous username format will be replaced with a numeric system using the student’s identification number. This number is a unique identity, generated by the Student Information System (SIS) and assigned to each student for the duration of their learning at TVDSB. 

The SIS identity for each student can be found in the following locations:

Please note that SIS identification numbers are not the student’s Ontario Education Number (OEN).

Students are asked to log out of all services on the evening of Monday, January 16, 2023, in order for these changes to take place.
