Which of the following details about the uniform is NOT required?

The detail about the uniform that is not required is the inclusion of the school name. While uniforms must meet various specifications regarding numbers and color to ensure consistency and identification during a match, having the school name on the uniform is not a mandated requirement. The primary focus for uniforms in volleyball is that they are identifiable with numbers and uniformity in color among team members, facilitating easier officiating and spectator recognition. Thus, while it may be beneficial for a team to include their school name for branding purposes, it is not a formal regulation within the rules governing volleyball uniforms.
