This week, MHSAA officials coordinator Sam Davis explains the differences in high school pass interference rules from those at the college and pro levels.
Be The Referee is a series of short messages designed to help educate people on the rules of different sports, to help them better understand the art of officiating, and to recruit officials.
Below is this week's segment – Pass Interference – Listen
One of the big differences between high school football and the college or pro game is how pass interference is called.
In high school, there is no such thing as an “uncatchable” pass. If there is illegal contact by the defender while the ball is in the air, that’s pass interference, no matter where the pass ultimately ends up.
Also – in high school – a defender can “face guard” as long as no contact is made with the receiver. That is not pass interference, even if the defender does not look back for the ball.
Both of those interpretations differ from the college and pro game. Both (of those) levels have an uncatchable exception, and neither allows for face guarding.
Keep that in mind the next time you think you’ve spotted pass interference at the high school level.

Be The Referee is a series of short messages designed to help educate people on the rules of different sports, to help them better understand the art of officiating, and to recruit officials.
Below is this week's segment – Volleyball Libero Uniforms - Listen
Before the match begins, a volleyball team takes the court wearing super-stylish, brand-new jerseys. The libero is in a bright neon top, but two other teammates also have the same neon sleeves.
At first glance, it looks like multiple liberos are on the floor. As the referee, you must check carefully: Under current NFHS uniform rules, the libero’s jersey must clearly contrast from all other teammates in color, design, and trim.
Accessories like sleeves or leggings are permitted, but they cannot confuse the identification of the libero. In this case, because the libero’s jersey color is the same as teammates’ sleeve color, the contrast is not sufficient, and the coach must correct it before play begins.
This ensures quick identification for substitutions, scoring, and libero actions.
