News - Ontario Secondary School Literacy Test (OSSLT)

​​​Ontario Secondary School Literacy Test (OSSLT) UPDATE

Successful completion of the O.S.S.L.T. is a graduation requirement. In order to prepare for the O.S.S.L.T., we are offering a 4 day O.S.S.L.T. Prep Course for Grade 10 students and for those Grade 11 and 12 students who are missing the OSSLT requirement. The purpose of this Prep Course is to help familiarize students with the test’s new online format as well as go over core literacy skills that will be assessed. We highly recommend your child’s attendance in this program. This course will run November 6, 7, 8, 9 from 2:30pm to 3:30pm after school in person. Please see the documents below for further information.
