For school owners and parents evaluating international pathways, few credentials carry the weight of the Ontario Secondary School Diploma. Understanding how to get OSSD certification is the first step toward opening doors to leading universities worldwide. This guide breaks down exactly what earning the diploma involves, from enrolment to graduation, and how partner schools and families can bring the program to their students.
The Three Core Requirements: Credits, Literacy, and Community Hours
Every graduate of an Ontario secondary school must satisfy three requirements set by the Ontario Ministry of Education. These are non-negotiable, standardized, and applied consistently whether a student studies in Toronto or at an international partner school.
- Thirty credits. Students must earn a total of 30 credits across Grades 9 to 12. This total is split into 18 compulsory credits and 12 optional credits. The compulsory credits cover foundational subjects: English, Mathematics, Science, a secondary language, History, Geography, Civics and Career Studies, the Arts, and Physical Education. The 12 optional credits are chosen from the school’s full course offering, giving students the freedom to pursue their interests and strengthen their university applications. One credit is granted for each course completed with a minimum average of 50%.
- The Provincial Literacy Requirement. Each student must demonstrate essential reading and writing competency. This is met either by passing the standardized Ontario Secondary School Literacy Test (OSSLT), offered once a year by the Education Quality and Accountability Office, or by completing the Ontario Secondary School Literacy Course (OLC4O). The literacy course is available only to students who have already attempted the OSSLT without success.
- Forty hours of community involvement. Students must plan and complete a minimum of 40 hours of community involvement activities. The requirement is designed to build a sense of civic responsibility and belonging, encouraging young people to understand the roles they play beyond the classroom.
Meeting all three requirements is the definitive answer to how to get OSSD certification. There are no shortcuts, but the pathway is clear and well-supported.
Step-by-Step: From Enrolment to Meeting University Prerequisites
Understanding the requirements is one thing; navigating the journey is another. Here is how the process unfolds in practice.
Step 1 — Enrolment and registration. A student registers with an Ontario-inspected school authorized to grant the diploma. At Rosedale Global High School, students enrolling through an international partner school are registered centrally, and each receives a nine-digit Ontario Education Number (OEN) assigned by the Ministry of Education. This number follows the student throughout their secondary education and anchors their official records.
Step 2 — English placement. Because the OSSD is academically rigorous, students from non-native English-speaking backgrounds complete an English Placement Test to confirm their readiness. A qualifying IELTS, TOEFL, Duolingo, or Cambridge score may be submitted in place of the test. This step ensures accurate course recommendations and sets students up to succeed.
Step 3 — Course enrolment and credit accumulation. Students begin earning credits toward the required 30. Each successfully completed course, at 50% or above, is posted to the Ontario Student Transcript, a provincially standardized record recognized by universities across Canada and around the world.
Step 4 — Ongoing evaluation and reporting. Progress is tracked through Ontario report cards, issued at the midpoint and conclusion of each course. Grades are reported as percentages, and report cards also assess six learning skills, including responsibility, collaboration, and initiative. This progressive evaluation model weighs term work throughout the course rather than resting a student’s future on a single final exam.
Step 5 — Meeting literacy and community requirements. Alongside coursework, students complete their 40 community involvement hours and satisfy the literacy requirement.
Step 6 — Graduation and university application. Once all three core requirements are met, the diploma is issued. Graduates apply to global universities as students of an Ontario high school. The OSSD is accepted worldwide without additional external testing, and high achievers whose six best Grade 12 courses average above 80% also receive the Ontario Scholar Certificate.
Earning the OSSD as an International or Online Student
One of the diploma’s greatest strengths is its accessibility beyond Canada’s borders. Students do not need to relocate to Ontario to graduate.
Rosedale Global High School is an independent, Ontario-based secondary school inspected by the Ontario Ministry of Education and authorized to grant the diploma. It centrally manages academic administration, curriculum, and evaluation from its head office in Toronto, delivering the program through a digital learning platform. International partner schools provide classroom instruction, learning facilitation, and local student services, while Rosedale’s Ontario Certified Teachers handle central evaluation to guarantee accuracy, consistency, and academic integrity.
For students who join after Grade 9, Prior Learning Assessment and Recognition (PLAR) is available. Rosedale’s counselling team assesses a student’s previous transcripts and grants equivalent credits for prior learning, so students transferring from other systems are not required to start over. This flexibility makes the diploma a realistic goal for learners entering at various stages of their secondary education.
FAQ: OSSD Equivalents and Rosedale Education
Is the OSSD equivalent to a high school diploma in my country?
Yes. The OSSD is a full secondary school graduation credential, consistently ranked among the world’s strongest education systems by international assessments. It is recognized by universities globally and is treated as equivalent to, and often stronger than, standard national secondary diplomas.
Can students earn OSSD credits for studies completed elsewhere?
Yes, through PLAR. Students admitted after Grade 9 can receive equivalent credits based on prior learning, assessed by Rosedale’s counselling team.
Do students need to sit external university entrance exams?
Generally, no. The OSSD is accepted globally without the requirement of additional external testing, though individual universities may have their own supplementary criteria.
Who is authorized to grant the diploma?
Only Ontario-inspected schools such as Rosedale Global High School may grant it. Partner schools deliver instruction locally but do not hold the authority to issue OSSD credits themselves; all credits and evaluations are centrally managed by Rosedale.
How is student progress tracked?
Through the OEN, the Ontario Student Record, and the Ontario Student Transcript, alongside standardized report cards, all managed centrally and reported to the Ministry of Education.
