He will play for Duke University in the Atlantic Coast Conference (ACC) in the 2017–18 season.Bagley attended Corona del Sol High School in Tempe, Arizona as a freshman and Hillcrest Prep in Phoenix, Arizona as a sophomore. In 2016, he transferred to Sierra Canyon School in Chatsworth, California. He was ruled ineligible to play his first year at Sierra Canyon due to California Interscholastic Federation (CIF) rules.
