Welcome to MAVO

   We are the only volleyball officials association recognized by the Maine Principals’ Association. MAVO provides trained and certified officials for all high school volleyball in Maine. Our members include officials certified by the NCAA (through PAVO), USA Volleyball (USAV), and the NFHS.

Potential work year-round

   Our members can stay active year-round. The season begins with girls’ high school volleyball in late summer through mid-fall, followed by USAV tournaments in winter and spring. Experienced officials also have opportunities to officiate college matches, typically from late summer to mid-November.

We are some of the best-trained high school sports officials in Maine

   MAVO offers extensive training for its members. Starting in March, officials can attend our annual Rookie Officials’ Bootcamp for hands-on development. Our most intensive on-court training runs from late June through July, followed by classroom sessions and preparation for the NFHS high school volleyball exam.New officials who fully participate in this program are well prepared to step onto the court for their first match.

Two questions every potential

MAVO official asks:


1. How much does it pay?
   MAVO officials are among the highest-paid high school sports officials in Maine. Most assignments include at least a JV and varsity doubleheader, and often freshman or First Team matches as well.


2. What does it cost?   There are some upfront costs in your first season. For a full breakdown, click the button. The good news: most officials earn back nearly all of those costs by mid-season through game fees paid by host schools.

Important Registration Information for Aspiring Collegiate Officials


 f you plan to officiate at the college level in 2026, be sure to register with Professional Association of Volleyball Officials (PAVO) by June 30. This allows your assigner to properly prepare you for matches. If you’re interested in moving up, let your assigner know so they can guide you through the process.


   It’s recommended that you have at least a couple of years of high school or USAV officiating experience before making the jump. Another option is to start as a collegiate line judge for a season or two to get comfortable with the speed of the college game.

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.

Shop for uniform shirts

Your gear


In addition to your uniform, you will also need to purchase some additional equipment. These items are not optional.


Every official needs the following:


1. Volleyball net measuring chain.

2. Handheld ball pump.

3. Pressure gauge.

4. Red and yellow sanction cards.

5. Coin for determining serve.

6. Gear bag.

7. MAVO patch.

8. Whistle with lanyard.

9. Digital watch with second hand or timer function.


Every official should have the following:


1. Set of ear plugs.

2. Hand sanitizer.

3. Set of Line Judge flags.

Shop for gear

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.
