What must all wrestlers do before competing at a high school event?

Before competing at a high school wrestling event, all wrestlers are required to weigh in. This is a critical procedure as it ensures that each athlete is competing in the appropriate weight class, maintaining the integrity of the competition and the safety of the participants. The weigh-in process typically occurs right before the event and is supervised to ensure that all athletes comply with the weight regulations set by the governing body of the sport.

Weighing in is essential for fair competition, as significant disparities in weight can lead to safety concerns and unfair advantages. This practice is regulated, and wrestlers must meet the weight limits for their respective classes to ensure that matches are competitive and safe.

The other options, while important in the context of overall participation and compliance with various requirements, do not have the same immediacy or necessity as the weigh-in in relation to competition readiness. For example, submitting a medical history form is important for athlete safety, but it is typically done well in advance of competition and does not directly affect the immediate readiness to compete on the day of an event.
