The High Mountain Institute offers an honors and AP-level curriculum that prepares students for success in the remainder of their high school career and beyond. We design our courses to closely match the content and rigor of our sending schools in order to facilitate smooth transitions home for our graduates. HMI is accredited by the Association of Colorado Independent Schools, an affiliate of the National Association of Independent Schools.

Students at HMI thrive in small-class settings with a 4:1 student to teacher ratio

At HMI, all students are exposed to a completely new academic environment where they are challenged by the diversity of perspectives brought by teachers and peers. Small class sizes (an average of ten students) and a focus on student-led discussion create an inclusive environment where every student participates. Our place-based curriculum connects students with the history, culture, and geography of the American West, while covering key topics necessary for junior and senior year academic progressions. Student-teacher relationships develop beyond the classroom through wilderness expeditions and residential life.

Students take 5-6 courses at HMI and can earn an ungraded ½ credit for physical education. Many students also participate in community service, particularly during the Fall Semester. If HMI does not offer a course that is necessary for a students academic trajectory at their sending school, students have the option to participate in an independent study.
