Montessori high schools include students aged 14 to 18, the equivalent of grades 9 to 12 in most schools. In Montessori high schools, students do lots of independent and group work. They also begin note-taking, assignments, and tests, to prepare for university. Below, we list Montessori high schools. These schools can be filtered for several different features.

Some schools aren't Montessori schools, but use a Montessori approach for their preschool or daycare program. This approach gives young learners plenty of freedom to choose tasks and activities that interest them, which promotes their independence and confidence. It also strongly emphasizes concrete learning, where children work with lots of hands-on materials, and do practical life activities. Children usually work independently or in small groups in these programs.

Montessori high schools emphasize self-directed learning, group projects, and challenging coursework. Their overall approach to education is progressive, contrasting with more traditional mainstream schools.
For a broader discussion of Montessori high schools (as well as preschool, middle school, and elementary school), see our main Montessori school guide.
In some Montessori high schools, students have long uninterrupted work periods, often two to three hours, allowing them to focus on self-chosen tasks.
Students also work through a rigorous curriculum covering compulsory subjects such as math, science, history, and English, with optional courses in geography, economics, and psychology. Montessori high schools in Canada prepare students for university or college, assigning tests, assignments, and grades—though typically fewer than mainstream schools.
Students earn credits and grades for courses, and their curriculum must meet provincial Ministry of Education standards. For more details, see our guide to Montessori curriculum.
Child-specific advice on choosing a Montessori school
Explore our child-specific insights on school choice, including Montessori schools. Selecting the right school depends on a child’s unique traits, such as mental focus, academic focus, social tendencies, and activity level.
To customize over 350 school profiles for your child’s unique traits, create a child profile through an Our Kids user account.
The Montessori teaching approach in high schools is distinctive. Lectures are occasional and brief. Teachers focus on ensuring mastery of core subjects but rarely lecture from the front of the classroom. Students do not sit in rows at desks like in mainstream schools.
Textbooks are often personalized to each student’s learning level, rather than using a single text for the entire class. Students can work independently or in groups on projects, with guidance from the teacher, and have considerable freedom to choose their tasks and work at their own pace.
