Cass Tech Building Update: Wednesday, May 2, 2018

Dear Cass Tech Families and Staff,

As you should know, we informed you yesterday evening through a robocall that school was open today. That information was accurate. Unfortunately, the city’s three major TV stations reported, without confirmation, that the school would be closed. We immediately contacted the media to retract the misinformation.

Although there appear to be continuing complaints of an odor, the District performed a quality air test and the building was cleared for use.

Due to the TV stations’ error, all student and teacher absences will be waived for today, Wednesday, May 2, 2018.
