The Ontario Secondary School Literacy Test (OSSLT) is typically written in Grade 10 by all students who are working toward achieving the Ontario Secondary School Diploma. The purpose of the OSSLT is to determine whether or not students have acquired the literacy (reading and writing) skills that they are expected to have learned by the end of Grade 9 as outlined in the Ontario curriculum. Students must meet the Provincial Secondary School Literacy Requirement in order to graduate, and OLC4O, the Ontario Secondary School Literacy Course, is an option for students who have not been successful in writing the OSSLT.

Eligibility and Outcome

OLC4O is a grade 12 open level course that is offered only to students who have been eligible to write the OSSLT at least twice and who have been unsuccessful at least once. This course is designed to help students acquire and demonstrate the cross-curricular literacy skills that are evaluated by the OSSLT. Students who complete the course successfully will meet the provincial literacy requirement for their Ontario Secondary School Diploma.

Course Content

We recently launched an updated version of OLC4O, which enables students to develop strategies that are used in decoding everything from titles, images, and texts, to writing longer pieces such as news reports and opinion essays. The course contains multiple-choice tests that provide students with immediate feedback on lessons. Exemplars that model concepts may be found throughout the course, and students are required to submit a final portfolio that contains their best pieces, fully edited, before they write the exam.


Student Support

Additional resources provided in our courses include access to FREE online tutoring throughout the course as well as ReadSpeaker, a text-to-speech tool, that enables students to listen to the notes and instructions in the course. This tool facilitates learning for students who face challenges in reading and writing and has proven most successful in the past.
