GLENDALE -- A student at Glendale High School brought a Confederate flag to an English class Wednesday and declared the day should be "White Privilege Day," a school spokesperson confirms.

Wednesday also happened to be the final day of class for seniors, who will graduate on Sunday.

"This action disrupted the class and is in violation of district policy," Superintendent Dr. Robert Kobylski said in a statement. "We conducted an investigation that resulted in disciplinary action."

The extent of that discipline was not immediately clear. The school says personnel are available to assist students who wish to talk about the incident.

"Fostering an educational community based on tolerance and respect is of the utmost importance to the administration, faculty, and staff at Nicolet," the statement says.
