Lone Peak High School (LPHS) opened its doors in 2009 and serves students in grades 9-12. As the newest edition to the Big Sky School District, LPHS has a strong record of academic achievement, including an impressive university acceptances list. Lone Peak High School is an IB World School offering the International Baccalaureate Diploma Program.  IB World Schools share a common philosophy - a commitment to high-quality, challenging, international education - that we believe is important for our students. For more information, please see the IB Diploma Handbook for grades 11 and 12 at the bottom of this page.

At Lone Peak, our teaching and learning are guided by a standards-based, constructivist approach. Utilizing Montana State Standards for Math, Language Arts, Science, and Social Studies, our study of core subjects is engaging and rigorous. Our Math program is an integrated approach where students are exposed to the major disciplines within Math each year but at a more sophisticated and abstract level as they progress through the program.  Our Science curriculum is discipline-focused on Biology, Chemistry, and Physics. In Language Arts, students study a wide range of literary works while continuing to cultivate their research skills as well as their written and verbal expression. Our Social Studies courses entail a global, national, and state perspective through the lens of  Government and History. 

In addition to the core subjects, students at Lone Peak High School receive a holistic education through specialist courses.  We offer an enriching course of study with a second language - Spanish, Music, Art, Design Technology, and Health Enhancement. Students may also opt to enroll in the Montana Digital Academy, BYU, University of Nebraska or Edgenuity to explore other interests and pursuits.  Students can also participate in a wide-range of extracurricular activities, which include: Mock Trial, Interact Club, National Honor Society, the Film Club, Student Council, Big Brothers Big Sisters, Thespian Society, A capella, and Yearbook.

To complement our curricular approach, students partake in experiential learning in the Greater Yellowstone Ecosystem and beyond. Students participate in the yearly Expedition, downhill skiing days, science field research,  and a myriad of local field trips to enhance the classroom experience. Guest speakers/experts are a regular feature at Lone Peak High School in our state-of-the-art Warner Miller Performing Arts Center.

The Diploma Program (DP) provides a challenging, internationally focused, broad and balanced educational experience for students aged 16 to 19. Students are required to study six subjects and a curriculum core concurrently over two years. The program is designed to equip students with the basic academic skills needed for university study, further education and their chosen profession. Additionally the program supports the development of the values and life skills needed to live a fulfilled and purposeful life.

To ensure the broadest possible reach of its academic programming for students, the school's IB Diploma Program is founded on an open enrollment policy that is supported through the school’s course selection process. All students in grades 11 and 12 have access to IB courses and may participate in the program as diploma candidates or course candidates.
