He was a McDonald's All-American in high school in Missouri and played college basketball for the Duke Blue Devils. Tatum was selected by the Boston Celtics with the third overall pick in the 2017 NBA draft and was voted to the NBA All-Rookie First Team in the 2018 season.

High school career
Tatum attended Chaminade College Preparatory School in Creve Coeur, Missouri. He was inspired by Bradley Beal, a senior at Chaminade, while Tatum was in his first year there as a seventh grader. Tatum struggled with the school's college preparatory curriculum, and his classmates were substantially more privileged than he was. Tatum played alongside Tyler Cook and was in gym class with classmate Matthew Tkachuk. Tatum wanted to play under his father, the head basketball coach at nearby Christian Brothers College High School, but his mother preferred Chaminade so Tatum would still work hard on academics.

As a freshman, Tatum averaged 13.3 points and 6.4 rebounds per game and was named 2013 Metro Catholic Conference (MCC) Co-Player of the Year, leading the Red Devils to both MCC and Missouri District 2 crowns.

On July 11, the Eagles narrowly defeated future Duke teammate Harry Giles and Team CP3 74–73 in the Nike Peach Jam Semi-Finals with a game-winning buzzer-beater to advance to the championship game, where Tatum finished the game with 28 points and five rebounds. The next day, he had 24 points, seven rebounds, and four blocks in a 104–77 loss to the Georgia Stars and future Duke one-and-done Wendell Carter Jr. in the 2015 Nike Peach Jam championship game. During the Circuit, Tatum led the EYBL in scoring with 26.5 points to go along with 9.5 rebounds per game.

Before his senior year, Tatum made a verbal commitment to Duke University over North Carolina, Kentucky, and Saint Louis University.

As a senior in 2015–16, Tatum averaged 29.6 points and 9.1 rebounds and posted six 40-point games while leading Chaminade to its second Missouri Class 5A state championship. Among his senior year highlights were a 40-point, 17-rebound game in a 76–57 victory over Bentonville High School and its star Malik Monk, a 46-point game against Huntington Prep and Miles Bridges at the Cancer Research Classic, and a final 40-point game against DeMatha Catholic High School and future #1 NBA draft pick Markelle Fultz at the 2016 HoopHall Classic.
