If you are an international student, the Ontario Secondary School Diploma, or OSSD, is one of the most respected high school credentials in the world. Universities in Canada, the United States, the United Kingdom, Europe, and beyond recognize it. The good news is that you can now earn it fully online, from any country, at your own pace.
This guide breaks down exactly what international students need to graduate with an OSSD, how transfer credits work, and how to finish faster than you might expect.
What is the OSSD?
The OSSD is the official high school diploma of Ontario, Canada. It is granted by schools inspected by the Ontario Ministry of Education. Because it is a Ministry recognized credential, an OSSD earned online carries the same value as one earned in a classroom in Ontario.
For international students, that means a globally trusted pathway to university, without needing to move to Canada before you are ready. If you want the full picture of how our school works, read Why Choose Royal Ontario Academy?
OSSD graduation requirements at a glance
Every student, whether in Ontario or overseas, must meet the same core requirements to earn the diploma:
- 30 credits total. This includes compulsory credits and optional credits. The number of compulsory credits depends on when a student started Grade 9. Students who began Grade 9 in September 2024 or later complete 17 compulsory credits, while earlier cohorts complete 18.
- 40 hours of community involvement. These are volunteer activities that can often be completed in your home community.
- The literacy requirement. Students must pass the Ontario Secondary School Literacy Test, known as the OSSLT, or complete the approved literacy course.
- Two online learning credits. Under Ontario policy, students earn a minimum of two online learning credits, with opt out provisions available.
Depending on when you began Grade 9, additional graduation requirements may apply. Students who entered Grade 9 in September 2024 or later must complete a Grade 9 or 10 Technological Education credit and one credit from the STEM-related compulsory course group. Ontario also introduced a financial literacy graduation requirement in Grade 10 mathematics beginning in September 2025.
Do international students need a study permit?
Students completing ROA courses online while remaining outside Canada generally do not require a Canadian study permit. You study from home, on your own schedule, and graduate with a recognized Ontario diploma.
This is one of the biggest advantages of the online model for international families. You can begin building your Canadian credential now and make decisions about studying abroad later.
A study permit may be required if you plan to enter Canada for in-person study. Always consult current IRCC guidance for your circumstances.
English proficiency: what you actually need
Many international students worry about English requirements. Here is the practical picture.
To succeed in Grade 12 university preparation courses, you need a solid working level of English. Some schools ask for proof through a test such as IELTS, TOEFL, Duolingo, or a Cambridge exam, while others use a placement assessment at registration. If your English is still developing, taking English credits within the OSSD itself helps build the exact academic language universities expect.
The key point is that strong English support is built into the diploma. You are not left to figure it out alone.
Transfer credits: how PLAR can save you time and money
If you have already completed high school courses in your home country, you may not need to start over. This is where PLAR comes in.
If you completed secondary school courses outside Ontario, the principal will review your official academic records to determine how many equivalent Ontario credits may be granted. Mature students may also qualify for Prior Learning Assessment and Recognition, known as PLAR. The appropriate process depends on your age, previous education, and enrolment status.
Typically, students completing their diploma from outside Ontario still take a set number of Ontario credits, including Grade 12 English, to satisfy graduation rules. A proper PLAR assessment tells you exactly where you stand, so you never repeat work you have already done.
At Royal Ontario Academy, PLAR assessments are free. We review your records, recognize prior learning where the Ministry allows, and build a clear plan for the credits that remain. For a full walkthrough of how the process works for students coming from another country, read our PLAR Guide for International Students: Earning the OSSD.
Which courses matter most for international students?
Most international students come to ROA for Grade 12 university preparation credits, because these are the courses universities look at for admission. The most in demand are:
- Grade 12 English (ENG4U), required by almost every university program
- Advanced Functions (MHF4U)
- Calculus and Vectors (MCV4U)
- Biology (SBI4U)
- Chemistry (SCH4U)
Missing even one of these can delay a university offer. We explain this in more detail in The Hidden Roadblock: Missing Grade 12 Courses That Limit Study Abroad Opportunities. If you know the university program you are aiming for, choosing the right Grade 12 courses early makes admission far smoother.
How long does it take?
This is often the most welcome surprise. With flexible online learning, you can finish a course in as little as four weeks, or take up to six months if you prefer a steadier pace. Students on accelerated paths often take several courses at once to reach graduation and university admission sooner.
You choose the pace that fits your goals, your schedule, and your time zone.
