NBA Rising Stars Challenge

Rookie Challenge (1994–2011)

The Rookie Challenge, established in 1994, was originally competed by two randomly selected teams composed entirely of first-year players. This format was continued until 1996, when it was changed to pit rookie teams of both the Eastern and the Western Conference against each other. In 1999, the game was cancelled as a result of the NBA lockout. Since the 1998 rookie class did not compete that year, the game was revamped and featured a team of standout first-year players ('rookies') against a team of standout second-year players ('sophomores').

Rising Stars Challenge (2012–2021)

The format of the game and name was changed to the Rising Stars Challenge in 2012. For 2012 and 2013, the format was changed to having two teams drafted by Basketball Hall of Famers Charles Barkley (Team Chuck) and Shaquille O'Neal (Team Shaq). In 2014, the two teams were drafted by Chris Webber (Team Webber) and Grant Hill (Team Hill). The game format changed in 2015 to Team USA vs Team World, where each team should choose at least three Rookies and three Sophomores, and the squad of each team should have four back courts, four front courts and two swingmen.

Unlike regular NBA games, the game was divided into two twenty-minute halves plus multiple five-minute overtime periods, similar to men's college basketball. The participating players were chosen by voting among the league's assistant coaches. In the game, players wear their respective regular team uniforms, except for 2009, in which players wore fan-designed jerseys. The head coaches of the two teams are the lead assistant coaches of the NBA All-Star Game coach. Starting in 2009, two active NBA players were added to the game coaching staffs.

Tournament-style format (2022–present)

The format was then changed again in 2022. 28 players are selected: 12 rookies, 12 sophomores, and 4 NBA G League Ignite players. They will be drafted into four teams of seven, which are led and coached by members of the NBA 75th Anniversary Team via a draft, in commemoration of the NBA's 75th anniversary season. The coaches include: Rick Barry, Gary Payton, Isiah Thomas and James Worthy. The format itself is now a tournament, with a Final Target Score for each round: 50 points for the semifinals, and 25 points for the finals, for a total of 75 points total for the team that wins the tournament, another nod to the NBA's 75th anniversary.

The format was slightly altered in 2023. 28 players are still selected, but the pool now consists of 21 NBA rookies and sophomores, and 7 NBA G League players (not just limited to NBA G League Ignite). The Final Target Score for the semifinal games was lowered from 50 to 40. In 2023, the 21 NBA players were drafted into three teams led by Pau Gasol, Joakim Noah, and Deron Williams, while the 7 NBA G League players form a single team led by Jason Terry. In 2024, the coaches were Pau Gasol, Tamika Catchings, Jalen Rose, and Detlef Schrempf, with Schrempf coaching the G League team.
