High School — Flatirons Academy

High School Program

Our comprehensive High School program provides students with a meaningful, rigorous, and supportive liberal arts education. With the apostle Paul, we believe all things were created through Christ and for Christ, in whom all things hold together (Colossians 1:15-17). Therefore, our passionate and caring teachers invite students to learn as an act of worship of our Creator. With theological study as the keystone of a meaningful education, students learn, not only the knowledge and skills required for higher education, but the tools of learning for a lifetime.

academic schedule

Our academic schedule invites students into rhythms of grace and the opportunity to engage in the full high school experience. Through alternating academic blocks and the Bison Day schedule at the end of five day weeks, students have the opportunity for deep study, co-curricular engagement, and a social life. On Bison Day, students change pace from core classes to engage in worship through chapel, fellowship with friends through societies, read a great book, and receive help through additional access to teachers during tutorials. Bison Day is an essential element of our program supporting the academic success and development of each student.
