[ scoring 27 points in his final high school game to lead Roselle Catholic to a win in the state's overall Tournament of Champions.][Dzenis, Brian. "Roselle Catholic takes TOC title over Pope John", The Trentonian, March 23, 2015. Accessed November 27, 2020. "This year’s Tournament of Champions ended the way most of these games have ended at this stage of the postseason: on an anticlimactic note. Roselle Catholic didn’t have its best game, but the effort was enough to beat Pope John, 57–45, Monday night at Trenton’s Sun National Bank Center. In the matchup between Kentucky-bound Isaiah Briscoe and Moustapha Diagne, who will be a future teammate of TCA’s Malachai Richardson at Syracuse, Briscoe showed why he caught the eye of John Calipari. He led Roselle with 27 points on the final night of his high school career."] As a senior, Briscoe averaged 21 points, five rebounds and three assists per game. He models his game after Deron Williams and Tyreke Evans. Prior to his senior year, Briscoe led the AAU New Jersey Playaz to the championship at the 2014 Nike Peach Jam in South Carolina. He posted averages of 19.2 points and 5 assists over 23 total games in the Nike Elite Youth Basketball League (EYBL) in 2014. Isaiah finished as Rivals.com #10 nationally ranked player and the #1 point guard in the class of 2015.
He committed to Kentucky on November 13, 2014, live on ESPNU, becoming the third highest ranked point guard that John Calipari signed at the school. "(UK) puts me in the best position to play basketball after college," Briscoe said. "Calipari puts you on the highest stage. The last couple years, all his point guards have been in the NBA. I'm just trying to be the next one."[ He chose Kentucky over St. John's. He was the nation's consensus top point guard, was ranked No. 13 overall player by ESPN and Scout, No. 10 by Rivals, and No. 12 by 24/7 Sports recruiting services.] He helped lead Team USA at the 2014 FIBA Americans U18 Championships to a gold medal. He was a first-team Parade All-American in 2015. He was a McDonald's All-American Game, Jordan Brand Classic, and Nike Hoop Summit game selection.
College career
As a freshman, Briscoe averaged 9.6 points and 5.3 rebounds per game. However, he struggled with his shooting particularly from outside, hitting only 14 percent of his attempts from behind the arc. Coming into his sophomore season, he worked at playing more of a point guard role. He posted 12.1 points, 5.4 rebounds, and 4.2 assists per game as a sophomore.
At the conclusion of his sophomore season, Briscoe announced that he would forgo his final two years of collegiate eligibility and enter the 2017 NBA draft joining teammates De'Aaron Fox, Malik Monk, and Bam Adebayo becoming the fourth Kentucky Wildcat to do so.
