Education in Canada is a provincial responsibility, but schools are administered by local school boards. Kindergarten is for children who are four or five years old. Children begin formal full-day schooling in Grade 1, when they are about six years old. They must stay in school at least until they are sixteen. However, most students continue to finish high school. Some go on to college or university. Each year of schooling represents one grade. The school year extends from the beginning of September to the end of June. Elementary school includes kindergarten to about Grade 8. Secondary school or high school may start in Grade 8, 9, or 10 and it usually continues until Grade 12.
