What Are Prerequisites?

In the Ontario high school curriculum, prerequisites are courses that must be completed before a student can enroll in more advanced subjects. For example, students typically need to complete Grade 10 English before progressing to Grade 11 English. Prerequisites ensure that students have the necessary background knowledge to succeed in advanced coursework, building confidence and competence as they work toward their diploma. 

At Canadian Virtual School, we list all prerequisites in our course catalog to help students plan and track their academic progression. If you’re unsure of which courses to take, our academic advisors are available to help create a personalized study plan that aligns with your academic goals and interests. 

Frequently Asked Questions

Why are prerequisites important for high school courses?

Prerequisites are designed to ensure students are prepared for the academic demands of more advanced courses. Each prerequisite builds foundational knowledge, helping students develop the skills and understanding necessary to tackle complex topics in later grades. This preparation is crucial for subjects like mathematics, sciences, and language arts, where advanced learning often builds directly on concepts learned in previous courses. 

Our course catalog includes detailed descriptions of each course, including prerequisite requirements. When planning your high school credits, refer to these descriptions to understand the sequence of courses and ensure you meet any necessary prerequisites before enrolling in advanced subjects. Additionally, our admissions team and academic advisors are available to assist with course planning, providing guidance on selecting the right courses for your educational path. 
The Ontario Secondary School Diploma (OSSD) requires students to complete a specific sequence of courses, many of which have prerequisites.

Following the recommended sequence of prerequisites ensures you stay on track to achieve your diploma in a timely and effective way.
