The STEM Teacher will work with the teaching team to plan, teach, and oversee the stem curriculum from grades 9-12 within the framework of a Montessori Adolescent program.

The Montessori Adolescent Teacher accepts the challenge and the privilege of maintaining the role of a stable adult presence within the prepared adolescent environment. This professional is responsible for guiding the holistic development of the young people in the Adolescent Community as well as instructing students in academic disciplines.

Adults and students in the Montessori high school function in a community of learners in an atmosphere of mutual respect and support. The program provides a consistent, yet flexible, structure; high expectations for work and conduct; a system of accountability; opportunities for student-led learning; and a focus on problem-solving. The curriculum promotes independence, self-direction, metacognition, and critical thinking. At its core, the collective elements of the program are a means to build community, discover passion, deepen curiosity, and provide experiences for each adolescent to engage deeply and meaningfully in self-discovery.
