Ontario Secondary School Literacy Test

The purpose of the Ontario Secondary School Literacy Test (OSSLT) is to ensure that students have acquired the essential reading and writing skills that apply to all subject areas in the provincial curriculum up to the end of Grade 9. All students in public and private schools who are working toward an Ontario Secondary School Diploma are required to write the OSSLT in Grade 10. The test is administered at the end of March each year.



Students who have been eligible to write the OSSLT at least twice and have been unsuccessful at least once are eligible to fulfill the requirement through the Ontario Secondary School Literacy Course (OSSLC). Principals have the discretion to allow students to enroll in the course before they have a second opportunity to take the test, if the principal determines that it is in the best educational interests of the student (Ministry of Education Policy/Program Memorandum 127). Successful completion of the OSSLT or OSSLC is a graduation requirement.


Students who successfully complete this course will have met the provincial literacy requirement for graduation, and will earn one credit. The credit earned for successful completion of the OSSLC may be used to meet either the Grade 12 English compulsory credit requirement or the Group 1 additional compulsory credit requirement.
