Ontario Secondary School Literacy Test (OSSLT): 2023-2024

The OSSLT measures whether students are meeting the minimum standard for literacy across all subjects up to the end of Grade 9. Successful completion of the literacy test is one of the requirements to earn an Ontario Secondary School Diploma (OSSD). All students across the province write this test.

After writing the test at least once, if a student is still unable to pass the test, he/she can take OLC4O1: Ontario Secondary School Literacy Course in their Grade 11 or 12 year to meet the literacy graduation requirements for an OSSD.

Grade 11 and 12 students who were previously eligible and identified as needing to complete the Ontario Secondary School Literacy Test (OSSLT) will have the opportunity to write on Tuesday November 28, 2023.

St. Mary Grade 10 students will write on Tuesday April 23, 2024.

Practice Test
Students have the opportunity to become familiar with the online test and its platform through EQAO’s online practice test. The online practice test comprises two sessions, which include content from previous tests. The practice test is equivalent to the two sessions students will be completing during the live test. In addition, the practice test includes an introductory session that allows students to become familiar with the new online platform’s tools and functions
