Be the Referee: Block/Charge Calls
March 29, 2016
This week, MHSAA assistant director Mark Uyl explains what is often considered the most difficult call to make in all of sports officiating.
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 - Block/Charge - Listen
It’s often been said that the most difficult call to make in all of sports officiating is the block/charge in basketball.
When you’re watching your next basketball game, the key for the official in getting the play correct is determining whether or not the defender gets in a legal guarding position. Many times we’ll hear announcers and commentators talk about the defender having his feet planted and stationary; that actually isn’t required by the rule. The rules require the defender to be in a legal guarding position, which is a position where it’s facing the offensive player and they’ve established a position in advance of the offensive player.
If the defender is in illegal position, the contact is now a charge.

What's My Why: Official Jenna Schroeder
September 9, 2026
Jenna Schroeder, Berkley
Jenna Schroeder has been an NBA referee since 2020 and previously worked in the NBA-G League. Prior to officiating, she played basketball at Oakland University and Saginaw Valley State University.
She was an MHSAA-registered basketball official in 2003-04, 2005-06, and then from 2010-18, and also officiated girls lacrosse for four seasons. She's Clio's all-time leading girls basketball scorer and participated in the MHSAA Officials Legacy Program.
I got into it because I played basketball my entire life. I graduated college in 2009, during the housing crisis and no job prospects, so I tried refereeing and got bit by the bug and I’ve been obsessed with it ever since then.
“What’s My Why” is a weekly feature telling the stories of MHSAA-registered officials in their own words. If you’re an MHSAA official and would like to share your reason why, please submit a 15 to 45-second video, taken horizontally, to director of officials Sam Davis at [email protected].
