What is Secondary Education?

In the U.S., secondary education, commonly known as high school, typically includes grades 9-12. Secondary education students learn about general subjects, such as English, math and science, and complete elective courses. Secondary education schools take many forms and offer a variety of learning environments.

Secondary Education Structure

In the U.S., secondary education typically encompasses grades 9-12, but grades 6-8 also may be included in some school districts. Public high school is the most common form of secondary education. According to the National Center for Education Statistics (NCES), there were 98,577 public high schools in the U.S. during the 2020-2021 period.

In primary school, students generally are assigned to one classroom and one teacher for an entire academic year. In the typical secondary education structure, however, students attend various classes in different classrooms throughout the day. Class periods typically range from 30 to 90 minutes, with a different teacher conducting each class.
