The Ontario Secondary School Literacy Test (OSSLT) is typically written in Grade 10 by all students who are working toward an OSSD. The purpose of the OSSLT is to determine whether 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.
The OSSLT is administered in the spring (late March or early April) once per year. All students must write the test on the same day at the same time.
If a student does not successfully complete the test in Grade 10, (unsuccessful result or did not attempt at all) the student will have the opportunity to take it again the following year.
Students earning their OSSD from outside of Ontario can write the OSSLT at an alternative location (Keystone International Schools – Camlica Campus) with an invigilator who has been approved by the Education Quality and Accountability Office (EQAO).
