Black boys are disproportionately disciplined. It starts in pre-K

Black students, boys and students with disabilities are a minority in K-12 schools across the U.S., but are disciplined more than anyone else, according to a new Government Accountability Office study. The study found that the disproportionate discipline often starts in pre-school, where black students as young as three or four years old are being suspended or expelled from school. It also found that discipline rates were the same across poverty levels.

Why it matters: The study reveals that race, gender and disability are key factors in student discipline, even if they aren't consciously being considered. And family income levels nor the age of a student changes that.
