Welcome to
BASIS Flagstaff

Since opening its doors in 2011, BASIS Flagstaff has expanded and grown in ways that make us all proud to be the home of the Yeti! Now a full K–12 school, BASIS Flagstaff offers the rigorous BASIS Curriculum to families in the cool pines of Northern Arizona. Earning the #5 Best High School in the Nation designation from U.S. News & World Report in 2018, academic excellence happens across grade levels through a connected and cohesive curriculum that promotes student development and engagement. Our school culture is one where the spirit of support and cooperation encourages students and teachers to explore ideas, collaborate, and grow. It is not uncommon to see an eleventh-grade student helping a third grader with Mandarin, a history and a math teacher working to make connections between lessons, or the Dean of Students reciting poetry at a staff meeting. BASIS Flagstaff cultivates lifelong learners.
