Ontario Secondary School Literacy Test (OSSLT)

All students must successfully complete the Ontario Secondary School Literacy Test (OSSLT) requirement under the Education Quality and Accountability Office (EQAO) to earn a Secondary School Graduation Diploma (OSSD). For most students, this requirement is met through the administration of the OSSLT in the spring of Grade 10.

The test is based on the Ontario Secondary School Curriculum expectations for language and communication, particularly reading and writing, up to and including Grade 9.

The test identifies areas for remediation for students who are unsuccessful in completing the test. Students who write the test but do not succeed may retake the test and must successfully complete both the reading and writing components to pass. There is no limit to the number of times the test may be taken.


Students who are receiving Special Education programs and services that have an Individual Education Plan (IEP) may receive the accommodations that are set out in the students' IEP.


Deferral of the test may occur for students who have been identified as exceptional and students registered in English as a Second Language (ESL)/English Literacy Development courses who have not yet acquired the level of proficiency in English required for successfully completing the test. The principal determines if a deferral should be granted and the time period for the deferral.


Students whose IEP indicates that they are not working towards the attainment of a Secondary School Graduation Diploma or Ontario Secondary School Diploma may, with parental consent and approval of the principal, be exempted from participating in the OSSLT.
