Which of the following is part of preventative officiating?

Preventative officiating is a proactive approach taken by referees and officials to ensure the smooth conduct of a match and to avoid any potential issues that could arise during gameplay. One key element of preventative officiating is checking line-ups prior to each set. This practice helps to confirm that all players are properly registered, eligible, and that the right number of players is on the court. By verifying these details beforehand, officials can prevent conflicts related to illegal substitutions or mismatched player positions, which can disrupt the flow of the game and lead to disputes.

In contrast, while entering player statistics and timing matches are important aspects of officiating, they do not directly contribute to preventing issues during the match itself. Player statistics are generally used for record-keeping and evaluation, while timing matches is essential for tracking the game duration but does not involve proactive measures to ensure compliance with regulations or prepare for potential disputes. Thus, checking line-ups stands out as a vital component of preventative officiating.
