The Ontario Education System is divided into four main levels: elementary, secondary, post-secondary, and adult education. Elementary education typically spans from kindergarten to grade 8, while secondary education covers grades 9 to 12. Students in Ontario must attend school until they are 18 years old or have completed their high school diploma. The system is publicly funded and overseen by the Ontario Ministry of Education. It includes various types of schools, such as public, Catholic, and private institutions. The curriculum emphasizes core subjects like math, science, and language arts, along with arts and physical education, ensuring a well-rounded education for all students.
