The Ontario Secondary School Literacy Test (OSSLT) is a mandatory standardized test administered by the Education Quality and Accountability Office (EQAO). It assesses whether students have the reading and writing skills necessary for success in high school and beyond. 

Administered by the Education Quality and Accountability Office (EQAO), the test is typically taken in Grade 10 and is a requirement for graduation.

The OSSLT evaluates students’ ability to:

• Read and understand a variety of texts
• Express ideas clearly in written responses
• Organize and develop arguments effectively

Students who are not yet successful on the OSSLT can rewrite the test.  Or, if they have been eligible to write the OSSLT at least twice and have been unsuccessful at least once, they can complete the Ontario Secondary School Literacy Course (OSSLC) as an alternative to meeting the graduation requirement.
