Unlocking the Secrets of a Great Volleyball Official

The clothes make the official, official

"Professionalism starts with our presentation at every match we officiate. Below are some essential do's and don'ts for selecting and wearing your uniform."

    Uniforms create a professional, consistent look, so wear them with pride and keep them in top condition. Your uniform should always be clean, pressed when needed, and free of wrinkles, stains, or damage. Replace any items that are worn or faded.

Start with quality basics: navy blue dress pants and clean, comfortable all-white shoes. Pants should be dress-style (no jeans, Dockers, or sweatpants), fit properly, and include pockets and belt loops for a black or navy belt.

Shoes should be used for indoor court wear only—never outside. They must be all white, including logos and laces. Choose comfortable shoes and wear all-white crew socks (no short or hidden socks).

Official shirts must be purchased from our approved vendor. White is required and serves as the default when there’s no agreement on color. Grey and cyan blue shirts are also available, in both short- and long-sleeve options.

If you wear an undershirt, it must match the uniform shirt color, and sleeves should not extend past the uniform. Do not wear a long-sleeve undershirt under a short-sleeve uniform—use the proper long-sleeve uniform shirt instead.

Your official shirts MUST have the above logo on the left sleeve.

NOTES:

• MAVO uniforms differ from the NFHS-required uniform and instead align with PAVO and USAV standards.
  
• Use a net measuring chain that works for both women’s and men’s net heights.
  
• Your whistle and lanyard should match. A whistle with a cushioned (rubber) mouth grip is recommended.
• Keep a backup whistle or two, and clean them regularly during the season.
  
• A ball pressure gauge is required and must accurately measure 4.2–4.6 psi.
• Combination pump/gauge units are a good option.
  
• Line judge flags must be red and sized between 12" x 12" and 16" x 16".
  
• A digital watch with a timer or countdown function is required.
  
• The MAVO patch must be worn on the upper right chest. It can be attached with Velcro or magnets (sewing is not recommended).
  
• NFHS rule and case books are included with your MAVO registration.
  Invest in a comfortable, durable pair of shoes—they make a big difference during long matches.
