I don’t know much about them but according to the article black students are ten times more likely to be suspended than white students.
Statistics don’t tell you all you need to know. It is all about behavior. I know more than a handful of educators who left the public school systems in Maryland because of race based reporting and punishment. The majority students end up being over-reported and punished to get the numbers to ‘look right’.
