The Ontario Secondary School Literacy Test (OSSLT) measures whether or not students are meeting the minimum standard for literacy across all subjects up to the end of Grade 9. Successful completion of the literacy test is one of the requirements to earn an Ontario Secondary School Diploma.
All students across the province write this test on the same date, usually in late March each year.
