At an awards ceremony last year for cheerleaders at Tremper High School in Kenosha, Wis., some of the students received awards called “Big Booty,” “Big Boobie” and “String Bean.” Similar awards had been given to students in 2017.

Now, prizes like those have been banned in the district.

Coaches described the mock awards as good-natured teasing, but some parents and students were appalled, and the event was challenged by the American Civil Liberties Union, which sent a formal warning to the Kenosha Unified School District last month.

On Monday, a letter from the district superintendent, Sue Savaglio-Jarvis, said that “the district has taken prompt and remedial action in order to protect the students and to prevent discrimination and harassment from occurring in the future.”

“Mock awards of any such kind per the date of this memo are strictly prohibited,” it added.

There was also a mandatory training session on discrimination and harassment for administrators, principals, assistant principals and supervisors on Monday. Dr. Savaglio-Jarvis said that district staff members would be disciplined or fired if they harassed students or saw harassment and did not report it.
