Are Math Courses Mandatory in Grade 12?
Share
For many students, math is one of the most challenging subjects. Without a foundational understanding of mathematical concepts, it’s hard to keep up with advanced math courses that not only challenge these concepts, but introduce new and more complex formulas. While mathematics is a constant component of education throughout elementary school, its role in high school raises additional questions. With increased freedom and flexibility in course selection during high school, students wonder whether math remains a mandatory subject in Grade 12. This article will clarify the requirements regarding math courses in Grade 12 and provide practical advice for students who are struggling with this essential subject.
Why Do You Have to Take Math in High School?
The requirement to take math in high school comes from the belief that mathematics is a foundational skill vital for success in various aspects of life, work, and further education. Math fosters the development of critical thinking and problem-solving abilities. By engaging with mathematical concepts, students learn to analyze information, identify patterns, and systematically approach challenges. These skills are applicable not only in academic settings but also in everyday decision-making and in various career paths.
Moreover, math is integral to many fields of study and professions. Careers in science, technology, engineering, and mathematics (STEM) require a solid understanding of mathematical principles. Even in seemingly unrelated fields such as art, psychology, and social sciences, a grasp of quantitative reasoning enhances research capabilities and leads to more informed conclusions.
Completing math courses in high school prepares students for post-secondary education and helps fulfill prerequisites for many college or university programs.

When Do You Have to Take Math?
Math is a mandatory course throughout Grade 9 and Grade 10, although student choice is limited during these early years. More advanced courses start in Grade 11, offering not only general mathematics courses but also options that focus on specific subjects. Some of the most popular Grade 11 to Grade 12 math courses are Advanced Functions, Data Management, and Calculus and Vectors. Each course presents a new level of difficulty and delves deeper into specific concepts. For the Ontario Secondary School Diploma (OSSD), students are required to have three math credits.
Are Math Courses Mandatory in Grade 12?
No. If you have taken a Grade 11 math course and have the three required math credits to graduate, math is no longer mandatory in Grade 12. Most students complete their final required math course in Grade 11, earning their third credit to graduate. While some students choose to continue their mathematics education by taking additional courses, it’s not required if this criteria has been met.
What If I Haven't Taken a Grade 11 Math Course?
If you haven’t taken or passed a Grade 11 math course, you will need to earn an additional math credit to graduate. Fortunately, being in Grade 12 does not necessarily mean you must take a Grade 12 math course. While Grade 12 math is the most advanced option, taking a Grade 11 math course in Grade 12 will still allow you to receive your required math credit.
Please note that you cannot fulfill your math credit requirement with a Grade 9 or Grade 10 course. One of your three math credits must be from either a Grade 11 or Grade 12 course. If you are struggling with math and unsure what course to choose, the best option is to take the general Grade 11 math course unless you feel confident in a specific area, such as algebra or geometry.
Who Should Take Math in Grade 12?
Even if you have fulfilled all mandatory credits, you may still want to take a Grade 12 math course depending on your future aspirations. Several career paths require Grade 12 math credits for admission to college or university programs. Here are a few examples:
- Engineering
- Computer Science
- Science
- Nursing
- Health Sciences
- Business
As a Grade 12 student, you should be making informed decisions about your future, whether pursuing a specific career or continuing your education. Carefully review the requirements for your desired path and confirm whether a particular math course is needed. Some university and college programs require general Grade 12 math, while others specify classes in targeted areas like Advanced Functions.
