For school owners looking to elevate their institution on the global stage, and for parents seeking a world-class academic pathway for their children, the Ontario Secondary School Diploma (OSSD) represents one of the most respected credentials in international education. But you do not need to be based in Canada to offer it.
Through an OSSD school partnership with Rosedale International Education, schools anywhere in the world can deliver this globally recognized curriculum to their students, right from their own campus. With more than 100 partner schools across 17 countries, Rosedale has built a proven model that helps institutions expand their academic offerings while giving students direct access to top universities worldwide.
This guide breaks down what an OSSD school partnership involves, how it benefits both schools and students, and the steps your institution can take to become a Rosedale school partner.
What an OSSD School Partnership Involves
An OSSD school partnership is a structured collaboration between your institution and Rosedale Global High School, an Ontario-based Canadian secondary school inspected by the Ontario Ministry of Education (BSID #668726). Rather than requiring your school to independently develop and manage a Canadian curriculum, the partnership model gives you access to a comprehensive, turnkey system.
Here is how schools offer the OSSD through this collaboration. Your school provides the classroom environment, local teaching staff, and student services. Rosedale supplies the transformative OSSD curriculum, a digital learning platform, centralized academic administration, and quality assurance services. All course evaluations are managed centrally by Rosedale’s team of Ontario Certified Teachers based in Toronto, ensuring consistency, academic integrity, and transparency across the entire global school partner network.
Students who enroll in the program register directly with Rosedale Global High School and receive an Ontario Education Number (OEN) from the Ontario Ministry of Education. Their academic records, including Ontario Student Transcripts and report cards, are maintained at Rosedale’s head office in Markham, Ontario, Canada. Upon meeting all graduation requirements, students earn the OSSD and can apply to universities around the world as Ontario high school graduates.
The partnership covers Grades 9 through 12, with more than 59 university-bound courses available across disciplines such as English, Mathematics, Science, Business, Technology, Media Arts, and Entrepreneurship. Schools can choose from several programming options, including a full OSSD high school program, a university pathway program, a creative industry specialty program, or an English language learning enhancement program.
Benefits for Schools and Students
Joining the Rosedale global school partner network delivers tangible advantages for both your institution and the families you serve.
For School Owners
Amplified international profile. Offering a globally recognized Canadian diploma positions your school alongside leading international institutions, helping you stand out in a competitive education market.
Growth in student enrollment. The OSSD attracts families who are actively searching for international academic pathways. Schools in the Rosedale partner network consistently report that the program draws new enrollment from students who might otherwise look abroad.
Operational efficiency through technology. Rosedale’s digital learning platform integrates seamlessly into existing classroom environments. Data-driven learning analytics, centralized evaluation, and a robust learning management system reduce the administrative burden on your staff while raising instructional quality.
Comprehensive teacher development. Rosedale provides extensive training programs and over 5,000 supplemental teaching resources, including detailed lesson plans and instructional strategies focused on higher-order thinking skills. Your teachers gain professional development that strengthens their classroom practice across all subjects.
Quality assurance you can trust. Rosedale’s centralized evaluation team ensures every student assessment meets consistent standards. This protects your school’s reputation and gives parents confidence in the integrity of the grades their children receive.
For Students and Parents
A globally recognized credential. The OSSD is accepted by universities around the world without the need for additional standardized testing. In 2024, Rosedale students received over 4,400 university offers, including acceptances to institutions such as the National University of Singapore, the University of Edinburgh, Imperial College London, and the University of Birmingham.
Personalized learning paths. Through Rosedale’s Individual Growth Plan (IGP), students work with counselors to design a course selection that aligns with their strengths, interests, and university ambitions. With more than 50 courses available, each student’s academic journey is genuinely tailored to their goals.
Skill development that matters. The curriculum emphasizes higher-order thinking skills, real-world problem solving, and global citizenship. Students do not simply memorize content; they learn to analyze, create, and communicate in ways that prepare them for success at the university level and beyond.
Local access to a Canadian education. Families no longer need to send their children overseas to access a high-quality international education. Students attend school locally while earning the same credential they would receive at a high school in Ontario, Canada.

Frequently Asked Questions About OSSD School Partnerships
What is the OSSD, and why is it recognized globally?
The Ontario Secondary School Diploma (OSSD) is the official high school credential issued by the province of Ontario, Canada. It is consistently ranked among the top education systems in the world by the Programme for International Student Assessment (PISA), which is administered by the Organisation for Economic Co-operation and Development (OECD). Universities across North America, Europe, Asia, and beyond accept the OSSD without requiring additional external standardized testing.
Does my school need to be accredited in Canada to offer the OSSD?
No. Your school does not need Canadian accreditation. Through the OSSD school partnership with Rosedale, your institution collaborates with Rosedale Global High School, which holds the Ontario Ministry of Education inspection and authorization to grant the OSSD. Rosedale manages all academic administration and compliance with Ontario regulations from its head office in Canada.
What are the OSSD graduation requirements?
Students must earn 30 credits (18 compulsory and 12 elective), complete 40 hours of community involvement activities, and meet the Ontario provincial literacy requirement. For students who enter the program after Grade 9, Rosedale offers Prior Learning Assessment and Recognition (PLAR) to grant equivalent OSSD credits based on their previous academic work.
How are student assessments managed?
All course evaluations are centrally managed by Rosedale’s Central Evaluation Team in Toronto. Student work is submitted through Rosedale’s digital learning platform and graded by experienced Ontario Certified Teachers. This centralized approach ensures accuracy, consistency, and academic integrity across all partner schools in the network.
Can the OSSD program run alongside my school’s existing national curriculum?
Absolutely. Many schools in the Rosedale global school partner network run the OSSD program alongside their existing local or national curriculum. The flexible programming allows schools to integrate OSSD courses into their schedules in a way that complements their current academic structure.
How quickly can a new school launch the OSSD program?
With Rosedale’s full-solution support, including curriculum, teacher training, and technology deployment, new schools can launch the program in as little as four to six weeks.
