The determination on playoff advancement for referees is based on referees’ overall evaluations from the regular season, as well as their performances in the previous round of the playoffs.  Those evaluations factor in analytical data and ratings by coaches, GMs and referee management.

Thirty seven Referees were selected for the First Round, while 30 are selected for the Conference Semifinals. The pool will be narrowed down to 20 for the Conference Finals and 12 for the NBA Finals.
