Pay attention!

Watch the lines when judging in/out. Don't watch the ball and see where on the floor it lands, watch the line and see if the ball hits it. It can make all the difference in the world.

On attacks, focus on the blockers hands and see if the ball hits it, don't watch the ball and then try to figure out if there was a touch.

Make your call, and make it crisply and demonstratively, without showboating. The referee wants to see your call right away and know you made it confidently, otherwise, he/she might have to overrule you.

Make your signal WHEN THE VIOLATION OCCURS, do not wait until the whistle has blown. The referee will sometimes be screened and unable to see if the ball has hit the floor, and will look to you for the signal. Be sure you have the call ready to go.

And make sure that when a violation occurs, that you ALWAYS signal, no matter how obvious the call is. If the serve goes 50 feet out of bounds, still signal out. Getting used to making the call on every rally will make you more confident to make your call right away on the real close ones.

Good luck!
