The Ontario Secondary School Literacy Course


The Ontario Secondary School Literacy Course (OSSLC) is designed to help students acquire and demonstrate the literacy skills that are evaluated by the Ontario Secondary School Literacy Test. Students who complete the course successfully achieving a final mark of 50% or higher, will meet the provincial literacy requirement for graduation and the Ontario Secondary School Diploma.


Students who have been eligible to write the Ontario Secondary School Literacy Test (OSSLT) at least twice, and have been unsuccessful at least once, are eligible to take this course to achieve both a Grade 12 credit and their literacy credential for graduation.

Mature Students

As of September 1, 2008, mature students may enroll directly in the OSSLC without first attempting the OSSLT. Successful completion of the OSSLC provides mature students an alternative means of demonstrating the required reading and writing competencies measured by the OSSLT. A mature student may still elect to meet the literacy graduation requirement by successfully completing the OSSLT.

A “mature student” is a student who meets all of the below criteria:

  • is at least eighteen years of age on or before December 31 of the school year in which he or she registers in an Ontario secondary school program;
  • was not enrolled as a regular Ontario day school student for a period of at least one school year immediately preceding his or her registration in a secondary program;
