How many seasons must pass after high school graduation for a player to be eligible for the NBA Draft?

A player must wait one full season after their high school graduation to be eligible for the NBA Draft. This rule was instituted to ensure that players have some time to develop their skills and readiness to compete at the professional level. It means that a player who graduates from high school can declare for the draft after they have participated in at least one NCAA season or played professionally internationally.

The timing allows players to either develop in college basketball or gain experience in other leagues, thereby enhancing their chances of a successful career in the NBA. This aligns with the NBA's commitment to ensuring that players are adequately prepared for the demanding competition of professional basketball.
