High school career
Before high school, Shumpert and fellow NBA player Evan Turner were teammates on the same 8th grade basketball team at Gwendolyn Brooks Middle School in Oak Park, Illinois.
Shumpert was first-team all-state player at Oak Park and River Forest High School and was one of the nation's top 30 seniors. He helped Oak Park and River Forest High School to three conference titles and was named conference MVP as a junior and senior. He was rated No. 15 among the nation's senior players by Scout.com and No. 26 by Rivals.com. Iman Shumpert was also selected to play in the 2008 McDonald's All-American Game

During the 2009-10 season, Shumpert underwent arthroscopic surgery to repair a damaged meniscus in his right knee on Dec. 3, and missed six games. He ended up the season as GT's third leading scorer, with 10.0 ppg. He was also second in the ACC in steals.
In the 2010-11 season, Shumpert led his team in scoring (17.3 ppg), rebounding, and assists, becoming only the seventh player in ACC history to do so. He ranked fourth in the ACC in scoring, 15th in rebounds, 10th in field goal and free throw percentage, and first in steals (seventh in the nation). He was named to the second All-ACC team and was a member of the conference's all-defensive team. Having impressed scouts with his defense and athleticism, Shumpert opted for the 2011 NBA Draft. Shumpert impressed scouts with his vertical jump, recorded at the combine of 36.5".
Shumpert was drafted with the seventeenth overall pick in the 2011 NBA Draft by the New York Knicks. Then teammate Jared Jeffries said that "he’s about as good an on-ball defender as there is in the league right now".Shumpert was selected to participate in the 2012 NBA All-Star Weekend Slam Dunk Contest, but was unable to due to a knee injury.
On April 28, 2012, during a first round playoffs game against the Miami Heat, Shumpert suffered a knee injury while dribbling in midcourt. He was immediately helped off the court. An MRI later revealed that Shumpert tore the ACL and meniscus in his left knee and would miss the rest of the season.
