What type of certification is required for scales used in weigh-ins?

The correct answer is annual certification. In the context of wrestling weigh-ins, scales must be accurate and reliable to ensure equitable competition among participants. Annual certification establishes a standard to verify that the scales are properly calibrated and functioning correctly. This requirement helps maintain the integrity of weight classifications and ensures that athletes are competing on a level playing field.

Scales may be subject to other forms of inspection or certification, but the annual certification is important as it reflects a commitment to regular checks and accountability. This consistent verification process is essential in a competitive environment where athletes closely meet weight limits for their respective classes.
