The NBA assigns referee crews based on multiple factors including official experience, performance ratings, travel schedules, and rest requirements. The league aims to distribute assignments evenly while ensuring high-quality officiating for all games. Crew Chief positions are typically assigned to the most experienced officials.

The Crew Chief is the leader of the crew with proficiency in all positions, responsible for high-level play calling and crew management. The Referee position serves as the glue for the crew through consistency and teamwork, carrying a larger workload than the Umpire. The Umpire focuses on aggressively and accurately calling plays in their primary area of responsibility with strong mechanics and rules knowledge. All three positions work together as a cohesive unit to officiate NBA games.
