For any school offering the Ontario Secondary School Diploma (OSSD), understanding every graduation requirement is essential. Among these requirements, the Ontario Secondary School Literacy Test, commonly known as the OSSLT, holds a central place. Whether you are a school owner evaluating an international curriculum partnership or a parent exploring the best academic pathway for your child, knowing what the OSSLT involves will help you make informed decisions. This guide breaks down everything you need to know about the OSSLT exam, from its purpose and format to how international students can fulfill the literacy requirement through the OSSD program.
What the OSSLT Is and Who Must Take It
So, what is the OSSLT exactly? The Ontario Secondary School Literacy Test is a standardized assessment created and administered by the Education Quality and Accountability Office (EQAO), an agency of the Ontario government. The test is designed to determine whether students have acquired the foundational reading and writing skills outlined in the Ontario curriculum through the end of Grade 9.
Successfully completing the OSSLT is one of 32 requirements students must meet to earn the OSSD. That means no student can graduate with an Ontario Secondary School Diploma without first satisfying the provincial literacy requirement. This applies across the board, whether a student attends a public school in Toronto, a Catholic school in Ottawa, or an international partner school delivering the OSSD in another country.
Most students sit for the OSSLT for the first time in Grade 10. However, eligibility begins once a student has earned at least eight credits, which typically happens after completing Grade 9. Students who do not pass on their first attempt are given the opportunity to retake the Ontario literacy test in subsequent years. If a student has attempted the test at least twice and has been unsuccessful at least once, they become eligible to enroll in the Ontario Secondary School Literacy Course (OSSLC), a credit course that can satisfy the same graduation requirement.
For schools and families considering the OSSD pathway, the OSSLT is an important milestone to plan for well in advance.
Format, Timing and How to Pass the OSSLT Exam
The OSSLT exam is a computer-based assessment divided into two sessions. Session A typically runs for about 65 minutes, while Session B takes approximately 75 minutes, though additional time is available for students who need it. The test uses a linear format, meaning every student receives the same set of questions in the same order.
The assessment evaluates two core skill areas: reading comprehension and writing. On the reading side, students encounter a variety of text types, including informational paragraphs, news reports, real-life narratives, and dialogues. They answer multiple-choice questions and provide short written responses that demonstrate their understanding of the material. On the writing side, students are asked to compose longer written pieces, such as an opinion essay and a news report. It is worth noting that all written work on the OSSLT is scored as first-draft writing, so students are not expected to produce polished, publication-ready text.
Scoring on the OSSLT uses a scale that ranges from 200 to 400. To achieve a successful outcome, a student must earn a minimum scale score of 300. Results are reported simply as “successful” or “not yet successful,” rather than as a percentage grade. The score does not appear on report cards and does not count toward any course mark. Instead, the Ontario Student Transcript records whether the literacy graduation requirement has been met.
EQAO offers the OSSLT during specific test windows each school year. For the 2025 to 2026 academic year, the fall administration window runs from November through early December, while the spring window falls between late March and April. Exact dates vary by school, so administrators should confirm the schedule with EQAO directly.
Results from the OSSLT are typically released approximately two months after the test window closes. Schools should plan accordingly and communicate timelines to families so that students and parents know when to expect outcomes.
The OSSLT for International Students
One of the most common questions from schools and parents outside Canada is whether international students pursuing the OSSD need to take the OSSLT. The short answer is yes. Every student working toward an Ontario Secondary School Diploma must satisfy the provincial literacy requirement, regardless of where they are located.
However, the pathway to meeting that requirement is flexible enough to accommodate students studying outside Ontario. International students enrolled in an OSSD program through e-learning or an international partner school outside the province may enroll directly in the Ontario Secondary School Literacy Course (OSSLC, course code OLC4O) to fulfill the literacy graduation requirement. This means they are not required to travel to Ontario to sit for the OSSLT in person.
The OSSLC is a full-credit course designed to help students develop and demonstrate the same cross-curricular literacy skills evaluated by the OSSLT. Successfully completing the course satisfies the provincial literacy requirement in the same way that passing the OSSLT does. For international students whose first language is not English, this course-based route can reduce the stress of a timed standardized test and provide a more supportive learning environment.
For schools that operate within Ontario or have the infrastructure to administer the OSSLT on-site, students may write the test at their registered school during the designated EQAO test windows. Rosedale Global High School, for example, centrally manages OSSLT registration for all eligible students through its head office in Toronto, ensuring that every learner in the network has a clear path to meeting the literacy requirement.
Regardless of the route chosen, the key takeaway for school owners and parents is that the OSSD literacy requirement is non-negotiable. Planning ahead and understanding the available options will help ensure that students stay on track for graduation.
Frequently Asked Questions About the OSSLT and Rosedale
Is the OSSLT the same as a final exam?
No. The OSSLT is not a course exam and does not count toward any individual course grade. It is a separate provincial assessment that measures whether a student has met the minimum literacy standard set by Ontario. A student’s transcript will simply indicate whether the literacy graduation requirement has been fulfilled.
What happens if a student does not pass the OSSLT?
Students who are unsuccessful on their first attempt can retake the OSSLT during the next available test window. After attempting the test at least twice with at least one unsuccessful result, a student becomes eligible to enroll in the Ontario Secondary School Literacy Course (OSSLC). Passing this course fulfills the same literacy requirement as the OSSLT.
Can international students skip the OSSLT entirely?
International students studying outside of Ontario through an accredited OSSD program may enroll directly in the OSSLC without first attempting the OSSLT. This provides a practical alternative for students who cannot access an in-person test administration site.
How does Rosedale handle the OSSLT for its partner school students?
Rosedale Global High School centrally manages academic administration for the OSSD, including registration of all eligible students for the OSSLT through the Education Quality and Accountability Office (EQAO). Students at Rosedale’s international partner schools receive clear guidance on how to meet the literacy requirement, whether through the OSSLT or the OSSLC. Grade 12 students who have not yet satisfied the requirement are supported in completing the literacy course to ensure they remain on track for graduation.
Does the OSSLT score affect university admissions?
No. Universities do not see the specific score a student earns on the OSSLT. They only see that the student has met the literacy graduation requirement on their Ontario Student Transcript. The test is a pass-or-fail benchmark and carries no weight in university admission decisions.
