Successful completion of the literacy test is one of the requirements to earn an Ontario Secondary School Diploma." - EQAO

The Facts at a Glance

  • All grade 10 students in Ontario write the OSSLT on the same day (usually in late March)
  • The test is designed to test your abilities in reading, writing, and following instructions
  • The test is written all in one day, usually in two 75-minute blocks during the morning with a brief break in between blocks
  • You need at least 75% (300 out of a possible 400) to pass the OSSLT
  • You write the test in grade 10, but if you're unsuccessful then you can write it again
