Ontario Secondary School Diploma (OSSD)

Rosedale centrally manages the academic administration of the Ontario Secondary School Diploma (OSSD) for Rosedale Global High School from our head office in Toronto, Ontario, Canada. Students attending Rosedale Global High School with an international partner school register with Rosedale Global High School and are granted an OSSD upon meeting the graduation requirements.

Why We Chose OSSD to Develop Rosedale Global High School

From inception, Rosedale’s objectives were clear:  

  1. Offer education with an emphasis on transformative competency development that will reshape the future of global education, while equipping students for our future world and to be the designers of their own path; 
  2. Create a program that fully values each student’s unique talents, allowing them to take ownership of their learning, reach their highest potential, and discover their personal definition of lifelong success; and,  
  3. Impact global education so it is accessible to more students around the world, while ensuring we scale its delivery for our international partner schools. 

With these clear objectives, and through a comprehensive analysis, we determined the Ontario Secondary School Diploma (OSSD) system provides a much stronger foundation and more flexibility than any other curriculum in meeting our objectives and supporting Rosedale’s vision of a transformative approach to learning.

We chose the OSSD because of its: 

1. Skill Focus

The OSSD curriculum emphasizes and develops 21stcentury higher order thinking skills and transformative competencies through curriculum design, evaluation and pedagogical practice. “The goal is to prepare students to solve messy, complex problemsincluding problems we don’t know aboutassociated with living in a competitive, globally connected, and technologically intensive world. (Ontario Ministry of Education, 21st Century Competencies Discussion Document)   

2. Equity and Accessibility

“The Ontario education system is based on a vision of an equitable and inclusive system…where every student is supported and inspired to succeed in a culture of high expectations for learning …”  (Ontario Ministry of Education, Ontario Schools: Policies and Programs).  In fact, Ontario’s education motto is “Support Every Child, Reach Every Student.”  The OSSD program is able to do this through a flexible system that adapts to individual student interests, strengths, learning styles and goals. Teachers are required to differentiate their instruction and evaluation to meet the needs of the learners so every child has the support they need to succeed.  

3. Progressive and Diverse Evaluations

Unlike education programs based on a standardized test model, the OSSD curriculum offersa progressive evaluation model that weighs all term work as a significant portion of astudent’s final grade. Through this model, students have multiple and diverse opportunities to demonstrate their learning throughout each course. The OSSD evaluation also allows a variety of formats of student work products (projects, case studies, reports, exams and more) in which a student has the ability to, and is required, to demonstrate their learning. The program provides educators the system-level support and flexibility they need to enable differentiated learning and evaluation. 

4. Global Recognition

The OSSD is a world-renowned differentiated education program and is consistently evaluated as one of the top education systems in the world by the Program for International Student Assessment (PISA), a triennial international study that evaluates education systems worldwide, from the Organization for Economic Co-operation and Development (OECD). The OSSD is also highly recognized by universities around the world.

Academic Adminstration

1. Ontario Education Number (OEN)

At registration, each student in Rosedale Global High School  is assigned an Ontario Education Number (OEN) by the Ontario Ministry of Education. The OEN is a 9-digit student identification number that is unique to every Ontario elementary and secondary student. It is used as the key identifier on a student’s school records and will follow the student throughout their elementary and secondary education. 

Rosedale uses the online platform to manage program academic administration and the required reporting for the Ontario Ministry of Education. Administrators from international partner schools can log in to review OEN’s directly.

2. Ontario Student Record (OSR)

The Ontario Student Record (OSR) is the ongoing, confidential record of an Ontario student’s educational progress. Each Ontario school keeps a hard-copy OSR for each student enrolled at their school and continually adds academic materials to it, such as, report cards, transcripts and other important documents. The OSRs of all students in Rosedale Global High School are securely held at the Rosedale Head Office in Toronto.

3. Report Cards

Student achievement in Rosedale Global High Schoolis formally communicated to students and parents through the Ontario report card. Report cards at Rosedale Global High School follow Ministry of Education report card templates. The report card focuses on two aspects of student achievement: the achievement of curriculum expectations and the development of learning skills.

  • Midterm report cards are issued when students have completed the first 50% of a course. 
  • Final report cards are issued within 10 business days of the student’s final exam. 

Each report card shows: 

  • The student’s percentage grade in the course 
  • The course median: This is the median of all Rosedale students taking the course 
  • The credit earned: If the course has been successfully completed, 1.00 credit will be awarded; if the course has not been successfully completed, 0.00 credits are awarded 
  • Grading teacher’s descriptive comments: Comments can be made about student strengths, areas in which improvement is needed, and ways in which improvement might be achieved  
  • Learning skills and work habits: Students are evaluated on a four-point scale in six categories: responsibility, organization, independent work, collaboration, initiative and self-regulation. E – Excellent, G – Good, S – Satisfactory, N – Needs Improvement   

The evaluation of learning skills, apart from any that may be included as part of a curriculum expectation in a course, are not considered in the determination of percentage grades.  


Grades in Ontario are reported as percentages in both and are defined as follows:

A credit is granted and recorded for each course in which the student’s grade is 50% or higher. 

4. OSSD Credit

Students receive one credit for each Ontario course they successfully complete at Rosedale Global High School. To earn the credit, the student must receive a minimum average of 50% in the course. Once the credit is successfully earned, the course and the grade will be posted on the student’s Ontario Student Transcript. 

5. Ontario Student Transcript (OST)

The Ontario Student Transcript is a provincially standardized document that provides a complete record of all Ontario secondary school credit courses taken. Any course completed successfully, withdrawn from or failed will appear on the student transcript along with the marks earned in each course. Transcripts can be requested at any time, and they can be sent to post-secondary institutions across Canada and worldwide. At graduation, the final transcript will be signed, sealed and sent to Rosedale’s international partner schools along with the Ontario Secondary School Diploma.

6. Ontario Secondary School Diploma (OSSD)

Rosedale issues the Ontario Secondary School Diploma, (OSSD) to students who meet all of the requirements laid out by the Ontario Ministry of Education. Upon successful completion of the program, students are able to graduate and attend post-secondary programs.   

Ontario Scholar Certificates (OSC) are also issued for Rosedale graduating students whose six highest Grade 12 courses have an average above 80%.  

The diplomas are sent to students at international partner schools at the time of graduation along with final transcripts.  

7. OSSD Graduation Requirements

Students have to meet the following three requirements in order to graduate from Rosedale Global High School with an OSSD.

Earn a total of 30 credits  

Students have to earn a total of 30 credits from Grades 9 to 12, including:  

  1. 18 compulsory credits, earned in English, Mathematics, Science, Secondary Language, History, Geography, Civics and Career Studies, Art and Physical Education.  
  2. 12 optional credits, earned in courses that the student may select from the full range of courses offered by the school.  

Students receive 1 credit for each course they successfully complete. To earn the credit, the student must receive a minimum average of 50% in the course.  

For students who are admitted to Rosedale after Grade 9, Rosedale offers Prior Learning Assessment and Recognition (PLAR). This process grants students equivalent OSSD credits based on their prior learning.   

Complete 40 hours of Community Involvement Activities  

Each student must find, organize and complete a minimum of 40 hours of Community Involvement Activities. The purpose of this requirement is to encourage students to develop an understanding of the various roles they play in their community, and to help them develop a greater sense of belonging within the community.  

The number of required hours depends on what grade the student enters Rosedale. Rosedale provides international partner schools with the guidance needed to help students meet the community involvement requirements.   

Meet the Provincial Literacy Requirement  

Each student must meet the Provincial Literacy Requirement by either successfully passing the standardized Ontario Secondary School Literacy Test (OSSLT) or passing the Ontario Literacy Credit Course (OLC4O). This requirement ensures that all students have the essential competencies in reading and writing that they will need to succeed at school, at work and in daily life.   

Under the direction of the Ontario Ministry of Education, the Education Quality and Accountability Office (EQAO) offers the OSSLT once every year. Rosedale Academy Head Office is responsible for registering all eligible students with the EQAO.  

Grade 12 students who are unsuccessful in passing the OSSLT must successfully complete an additional course, the Ontario Secondary School Literacy Course (OLC4O), to meet the literacy requirement for graduation. An additional fee will apply. Students cannot take the OLC4O without having attempted the OSSLT.  

8. Prior Learning Assessment & Recognition (PLAR) for International Students

For students who are admitted to Rosedale after Grade 9, Rosedale offers Prior Learning Assessment and Recognition (PLAR). This process is completed by Rosedale’s counselling team, and involves the assessment of an entering student’s prior transcripts and the granting of equivalent OSSD credits. Through PLAR, students can receive credits based on what they’ve previously learned.

9. English Language Placement Test

To ensure students can successfully complete the OSSD program and to make accurate OSSD course recommendations, the English Placement Test is administered to assess the student’s English level when entering Rosedale Global High School. The student’s CEFR levels are reported at the conclusion of the test. An IELTS/TOEFL/Duolingo or Cambridge Test score can be submitted at the time of registration in lieu of taking the test.  

This is mandatory for all students who are from a non-native English-speaking country or from an education system that is not taught full-time in English. Rosedale Global High School is an academically rigorous program and has set English Language Proficiency as one of the admission criteria to ensure students can succeed in the program.

Rosedale Academy also holds high standards of academic rigor and academic integrity through central management of course evaluation.  

Rosedale’s Grading Teachers also provide quality feedback to all students and collaborate with classroom teachers in partner schools to recommend personalized learning strategies and help students improve throughout the school year.
