How Credits Work in Virtual High School (OSSD Explained)
Quick Answer: In a virtual high school, Ontario students earn OSSD credits by completing ministry-approved online courses. To graduate with an Ontario high school diploma, you need 30 credits (compulsory and elective), complete 40 volunteer hours, and meet the literacy requirement. Online OSSD credits are fully recognized towards these requirements.
Online education has made it easier than ever to earn high school credits on a flexible schedule. How credits work in virtual high school is a common question for students and parents considering an online option. This comprehensive guide will explain how OSSD credits are earned online and counted toward the Ontario high school diploma. Whether you’re looking to earn high school credits online to graduate early, catch up, or balance other commitments, we’ll break down everything you need to know about virtual OSSD requirements and how online high school works.

What is the Ontario Secondary School Diploma (OSSD)?
The Ontario Secondary School Diploma (OSSD) is the official high school diploma awarded by the Ministry of Education in Ontario. It’s the credential you receive upon completing all Ontario high school diploma requirements, which include earning a set number of credits, completing community involvement hours, and passing a literacy test or course. The OSSD is recognized by colleges, universities, and employers across Canada and internationally. In other words, earning your OSSD means you have successfully completed the Ontario high school program.
For students, each course you take in grades 9 through 12 is worth a credit (or in some cases, half a credit). These credits are the building blocks of your diploma. So, what exactly is a “credit”? In Ontario, a high school credit typically represents 110 hours of coursework in a specific subject. When you pass a course (whether in a physical classroom or an online classroom), you earn one credit toward your diploma. OSSD credits earned online are no different – a credit earned through a virtual high school course counts the same as one earned in a traditional school.
How Do High School Credits Work in Ontario?
High school credits in Ontario are a way to measure your progress toward graduation. To earn the OSSD, students must accumulate a total of 30 credits in specific subject areas:
- 18 compulsory credits – These are required courses that every student must take, such as English, Math, Science, History, Geography, French (or another second language), Arts, Health and Physical Education, Civics, and Career Studies. (Civics and Career Studies are half-credit courses, usually taken in Grade 10, and together they count as one full credit.)
- 12 optional credits – These are elective courses that students choose based on their interests and future goals. Options may include courses like business studies, technology, additional sciences, languages, social sciences, or arts beyond the one compulsory arts credit. You have the freedom to select courses that align with your aspirations (for example, taking extra science courses if you’re interested in a science-related career, or more arts courses if you have a passion in that area).
Note: The Ministry of Education updated the requirements for students starting high school in recent years. For students who began Grade 9 in 2020 or later, there is now a requirement to earn at least 2 online learning credits as part of the 30 credits. (If you attend a virtual high school for your courses, you’ll automatically fulfill this online credit requirement.) Additionally, for students starting Grade 9 in 2024 and beyond, the compulsory credit count is 17 (with 13 optional credits) because a new Grade 10 financial literacy component has been introduced within the math curriculum. The overall total, however, remains 30 credits for an Ontario high school diploma.
Each credit corresponds to a course. When you successfully complete a course, you get a credit added to your transcript. If a course is a half-credit (like Civics or Career Studies), you need to complete both halves to earn a full credit. How credits work in virtual high school is essentially the same as in a traditional school – you take courses, complete the assignments and assessments, and upon passing, you earn credits. The key difference is how you take the course, not how the credit is awarded.
How Many Credits Do You Need to Graduate High School in Ontario?
You need a total of 30 credits to graduate high school in Ontario and receive your OSSD. These credits break down into the compulsory and optional credits explained above. Here’s a quick summary of the requirements to earn an Ontario Secondary School Diploma:
- 30 Credits in Total: Earn 30 high school credits, which include compulsory courses (like English, math, science, etc.) and elective courses of your choice.
- 40 Hours of Community Involvement: Complete a minimum of 40 volunteer hours. This is a requirement that encourages students to contribute to their community. You can fulfill these hours in various ways (charity work, school initiatives, community service projects) as long as they meet the guidelines set by your school or school board.
- Literacy Requirement: Pass the Ontario Secondary School Literacy Test (OSSLT) or complete the Ontario Secondary School Literacy Course (OLC4O). The OSSLT is usually written in Grade 10. If you don’t pass the test, or if you are an adult learner or someone with unique circumstances, you can meet this requirement by taking the literacy course instead.
- Online Learning Credits: (For students who started Grade 9 in 2020 or later) Complete at least 2 credits through online learning. Taking courses at an accredited virtual high school counts toward this requirement. Students do have the option to opt out of the online credit requirement via a formal process, but if you’re already earning your credits online, this requirement is automatically satisfied.
It’s important to note that these requirements are the same whether you attend a traditional brick-and-mortar school or a virtual high school. A virtual OSSD has the same value and requirements as any OSSD earned in-person. The difference lies in the delivery format of the courses, not in what you need to accomplish.
Can I Earn OSSD Credits Online?
Yes, you absolutely can earn OSSD credits online. Ontario’s Ministry of Education allows students to earn high school credits through accredited online schools. These schools, like Canadian Virtual School, are Ministry-inspected private schools that offer courses following the Ontario curriculum. When you complete an online course through a school inspected by the Ministry (with a Board School Identification Number, or BSID), the credit you earn is identical to one earned at any public high school.
Earning OSSD credits online is a flexible option for a variety of students:
- Current high school students can take online courses to supplement their timetable. For example, if your day school doesn’t offer a course you need or if you want to free up your schedule, you can earn high school credits online and have that credit count toward your OSSD. The online school will issue a report card and can send the credit record to your day school to be added to your Ontario Student Transcript.
- Homeschooled or remote students can complete all their high school credits through a virtual high school to earn an Ontario high school diploma from home.
- Adult learners who didn’t finish high school or need additional credits can enroll in an online high school course to work toward their diploma at their own pace, while balancing work or family responsibilities.
- International students can earn credits toward an OSSD online from their home country, which is helpful if they plan to attend university or college in Canada.
The key is to make sure the online school is recognized by the Ontario Ministry of Education. Credits must come from a Ministry-inspected institution to count toward your diploma. Canadian Virtual School, for instance, is accredited and grants OSSD credits that are accepted by universities and colleges. When you earn OSSD credits online through such a school, it appears on your official transcript just like any other credit.
How Does Online High School Work in Ontario?
How online high school works is a bit different from the traditional classroom, but the goal is the same: to help you complete courses and earn credits toward your diploma. Here’s how a typical virtual high school course functions:
- Enrollment: Unlike traditional schools that have semesters, many virtual high schools offer rolling enrollment. This means you can register for a course at any time of the year. Once you enroll and pay any required tuition fee for the course, you’ll be given access to the online learning platform.
- Course Materials: Courses are delivered through an online learning management system (LMS). You’ll find your lessons, assignments, readings, and resources all organized by units or modules. The curriculum in an online course is based on the same Ontario curriculum expectations as a regular school course. For example, Grade 11 Chemistry online will cover the same content and skills as Grade 11 Chemistry in a classroom.
- Self-Paced Learning: One of the biggest differences is that virtual high school courses are often self-paced. You can complete lessons and assignments on your own schedule. If you want to accelerate and finish a course in a few weeks or months, you can often do that (some students might complete a credit in as little as 4-8 weeks of focused work). Alternatively, if you need more time due to other commitments, many online courses allow you to spread out your work over several months (typically up to 12 months). This flexibility is a huge advantage for students who need a non-traditional schedule.
- Teacher Support: Even though you’re not in a physical classroom, you aren’t learning alone. Certified Ontario teachers are assigned to teach each online course. Your teacher will grade your assignments, provide feedback, and answer your questions via email, messaging, or even video calls as needed. Teachers might host occasional live sessions or virtual office hours, but generally the coursework is asynchronous (not in real-time), meaning you can do the work at the times that suit you.
- Assessments: Online courses have assessments just like regular courses. These can include quizzes, essays, projects, presentations, and sometimes proctored exams or supervised tests. For instance, a virtual high school may require a proctored final exam that you arrange to take under supervised conditions. (Some online schools use virtual proctoring services, while others might have you find an in-person proctor such as a librarian or teacher.) Other courses might replace final exams with major projects or cumulative assignments. All assessments in an online course are designed to evaluate the same expectations and learning objectives as an in-school course.
- Credit Achievement: When you have completed all the required assignments and assessments in the course and your teacher confirms you’ve passed (with a final grade of 50% or higher), you earn the credit. The school will issue a report card for that course. If the virtual school is your main school, they will record the credit on your Ontario Student Transcript (OST). If you attend a physical school and took the online course as an extra, you can provide the report card to your guidance counselor at your day school, and they will add that credit to your transcript.
How credits work in virtual high school ultimately comes down to this: you have the freedom to learn at your own pace, but you are still accountable for mastering the material and completing the assessments. The result – a credit on your transcript – is the same outcome you’d get from a traditional class, just achieved in a more flexible way.
What Are the Benefits of Earning High School Credits Online?
Choosing to earn high school credits online can offer several advantages compared to the traditional classroom route:
- Flexibility: Online learning lets you work at the times that are best for you. If you’re an early bird or a night owl, you can study when you’re most alert. You can also adjust your pace – speed up to finish a course sooner or slow down when life gets busy.
- Personalized Pace: In a virtual high school, you’re not forced to move at the pace of an entire class. If you grasp material quickly, you can move ahead without waiting. If you need more time on a challenging concept, you can take that time to master it before moving forward.
- Greater Course Selection: Sometimes your local school might not offer a particular course (for example, a specialized tech course or a higher-level language class). Online schools often have a broad catalog of courses, so you can take the subjects that align with your interests and goals. This can be especially useful for fulfilling specific credit requirements that you can’t meet locally.
- Comfort and Convenience: You can study from home or anywhere you have internet access. This can reduce stress and time spent commuting. It’s also a great option if you have health issues, busy training schedules (as with young athletes or performers), or other circumstances that make traditional school attendance difficult.
- Credit Recovery or Advancement: If you need to catch up on credits (credit recovery) or if you want to get ahead (maybe graduate early or take an extra credit to lighten a future semester’s load), online courses are an excellent solution. You can do summer courses online, or take an extra course during the school year without overloading your daily school schedule.
- Preparation for Post-Secondary: Online learning requires you to develop good time management, self-discipline, and initiative – skills that are extremely valuable in college, university, and the workplace. By taking responsibility for your learning now, you’ll be better prepared for the independence of post-secondary education.
Tips for Success in a Virtual High School
While the flexibility of online learning is fantastic, it also means you need to be responsible and organized. Here are some tips to help you succeed when earning credits through a virtual high school:
- Create a Schedule: Treat your online course like a real class by setting aside dedicated time for it each week. Make a schedule or calendar for when you’ll watch lessons, do readings, and complete assignments. Having a routine can keep you on track.
- Stay Organized: Keep all your study materials, notes, and assignments well-organized. Since everything is digital, create folders on your computer for each course. Use checklists to track completed lessons and upcoming deadlines.
- Avoid Procrastination: Without the daily reminder of attending class, it can be easy to procrastinate. Set short-term goals, like finishing a module by a certain date, to keep yourself motivated. Remember that how credits work in virtual high school depends on you making consistent progress – steady work each week will help you earn your credit on time.
- Ask for Help: Your online teachers are there to help you. If you don’t understand something, reach out. Don’t hesitate to email your instructor with questions or ask for a virtual meeting. Some schools also have online tutoring or discussion boards where you can get help from teachers and fellow students.
- Stay Engaged: Actively participate in any discussion forums or group activities if your course has them. Engaging with the material (and with peers, if possible) helps solidify your learning. Even if your course doesn’t have class discussions, make an effort to connect concepts together and reflect on what you learn.
- Keep Track of Requirements: Make sure you’re aware of any midterms, final exams, or major assignments that have special requirements (like needing a proctor or being due by a specific date). Mark these on your calendar early so they don’t sneak up on you.
- Use Available Resources: Take advantage of the resources provided – if there are review quizzes, practice tests, video tutorials, or extra materials, use them to reinforce your understanding. Many virtual courses include rich content like interactive lessons and videos; make sure to utilize these for a deeper grasp of the subject.
- Maintain Balance: While online courses let you accelerate, be careful not to burn yourself out by rushing too fast. Balance your studies with breaks, extracurricular activities, and rest. It’s important to maintain your well-being while pursuing your academic goals.
How many credits do you need for an OSSD?
To earn the Ontario Secondary School Diploma, you need 30 credits in total. This includes a set of compulsory credits (in subjects like English, math, science, etc.) and additional elective credits of your choice, adding up to the 30 required credits.
Can you get an Ontario high school diploma online?
Yes. You can earn an Ontario high school diploma (OSSD) online by taking courses through an accredited virtual high school. As long as the school is authorized to grant OSSD credits, the diploma you receive is the same credential you’d earn at a traditional brick-and-mortar school.
Are online high school credits accepted by universities and colleges?
Absolutely. Online high school credits from a Ministry-inspected Ontario school are accepted by universities and colleges. Post-secondary institutions care that you have the OSSD and the required prerequisite courses; it doesn’t matter if you earned those credits online or in a physical classroom.
How long does it take to complete an online high school course?
The time can vary. Many online high school courses are self-paced – motivated students might finish a course (earn a credit) in as little as 4-8 weeks. Other students might take a few months or up to a year to complete a course. The schedule is flexible, but you should check if your school has a maximum time limit (for example, one year to finish a course).
What are compulsory and optional credits?
Compulsory credits are the 17 or 18 specific courses the Ontario Ministry of Education requires all students to take (like 4 English credits, math, sciences, etc.). Optional credits (electives) are the courses you choose based on your interests to make up the rest of the 30 credits. Both compulsory and optional credits can be earned through virtual high school courses.
Do students have to take online courses to graduate now?
For students who started Grade 9 in 2020 or later, Ontario’s graduation requirements include at least two online learning credits. However, students can opt out of this requirement if they prefer. If you’re completing your high school through a virtual school, you will naturally meet this requirement without any extra steps.
Can adults return to earn high school credits online?
Yes, absolutely. Adults can earn high school credits online to complete their OSSD. Online high schools welcome adult learners who may need one or many credits to finish their diploma. The flexible online format is ideal for adults who are working or have other responsibilities while they study.
