Welcome to BASIS Flagstaff


The first BASIS charter school in Northern Arizona, BASIS Flagstaff opened in 2011 to serve 425 students in grades 5–12, adding 4th grade in fall 2015 and 3rd grade in 2016. BASIS Flagstaff now serves 650 students who go to school every day with the best view in all of Flagstaff. Last year, BASIS Flagstaff joined the Arizona Interscholastic Association (AIA), which opened up incredible opportunities for students to participate in sports and other activities.
Perhaps most notably, in the spring of 2016, BASIS Flagstaff received the extraordinary rank of #2 Most Challenging High School in the U.S. by The Washington Post. Additionally, the BASIS Flagstaff Class of 2016 was a group of 37 highly gifted, talented students who received a collective total of $2.8 million in merit aid. Among these 37 students, one was named both a National Merit Finalist and a National Merit Semifinalist, and five were recognized as Commended Scholars.
