Battier graduated from Detroit Country Day School with a 3.96 grade point average and was named the school's outstanding student in his senior year. He went on to attend Duke, where he played four years under head coach Mike Krzyzewski. While at Duke, Battier was often the best defender on the court. He frequently took charges which prompted the Cameron Crazies to chant, "Who's your daddy? Battier!" He led the Duke Blue Devils men's basketball to two Final Fours, in 1999 and 2001, though his team in 1998 squandered a late 17-point lead to eventual national champion Kentucky in the regional finals. The Blue Devils lost to the Connecticut Huskies in the 1999 NCAA Men's Division I Basketball Tournament, but came back to win the national championship by defeating the Arizona Wildcats two years later. In 2001, Battier was a consensus national player of the year with honors including the Naismith, Associated Press and "Sporting News" College Player of the Year awards; the John R. Wooden Award; and the Oscar Robertson and Adolph Rupp trophies. He subsequently had his jersey No. 31 retired by the Blue Devils. Additionally, Battier was a three-time awardee of the NABC Defensive Player of the Year. Battier (778) and Jason Williams on the 2001 national championship team were one of only two Duke duos to each score over 700 points in a season, the other duo being Jon Scheyer (728) and Kyle Singler (707) in the 2009–10 season. Battier graduated from Duke with a major in religion.
