AURORA, Ill. (CITC) – An Illinois STEM school is facing a federal civil rights complaint over a club which allegedly segregates students based on race in various activities. The complaint against the Illinois Math and Science Academy (IMSA) in Aurora, Ill. was filed Wednesday by advocacy group Parents Defending Education (PDE). It follows PDE obtaining documents showing the top-ranked high school offers an “affinity group” exclusively for Black and “Latinx” students.
