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.

The cost of Montessori high schools tends to be lower than the cost of other private high schools. In fact, Montessori schools are usually on the lower side of private school tuition in general. Private school tuition can range from $5,000 to over $30,000 per year for day students.

Some Montessori high schools offer needs-based financial aid, such as bursaries or tuition relief. Some offer scholarships (a form of merit-based financial aid). Check out our financial aid guide for more on these options.

Montessori high schools have lots of self-directed learning, group projects, and challenging work. Overall, their approach to education is progressive, and constrasts with more mainstream schools

For further discussion of Montessori high school (not to mention preschool, middle school, and elementary school), see our main Montessori school guide.

Montessori school curriculum

In some Montessori high schools, students have long uninterrupted work periods, of two to three hours. During these periods, students can often work on their own chosen tasks.

On the other hand, Montessori students need to work through a challenging curriculum. They must master material in compulsory subjects such as math, science, history, and English. And, they’ll have the option of taking other subjects, such as geography, economics, and psychology.

Montessori high schools prepare students for university or college. Unlike preschool and elementary schools, they give students tests and assignments. They also grade many of these (though less than in mainstream schools).

Students are also given credits and grades for courses. Like mainstream high schools, for students to graduate with a diploma, their curriculum must meet the standards of the Ministry of Education.

For more details, see our guide to Montessori curriculum.

Montessori teaching approach

Montessori high schools have an interesting teaching approach. Some lectures are given, though less than in mainstream high schools. Teachers must ensure students master the basics, especially in required subjects. Usually, though, the teacher doesn’t stand in the front of the classroom, and students don’t sit at desks.

Teachers use textbooks in some courses. Often, though, each student will have their own textbook, tailored to their special learning level. Rarely will there be one textbook for the entire class.

Students have the option to work alone or in groups to complete some projects, with some guidance from the teacher. Moreover, teachers give them quite a bit of freedom to choose their tasks and work at their own pace.
