Discipline in black and white
Why is it necessary to measure student behavior by race? Test scores are in this way disaggregated to prevent schools from ignoring struggling low-income and minority students, who in the past were often written-off as beyond hope. (Monitoring test scores by race is still problematic, I think, for lots of reasons, but at least its basic justification is strong.)
But what is the justification for observing in a study that black youngsters do worse with "Essential Life Skills"? Should teachers put extra effort into, I dunno, making sure that their minority pupils are suspended less frequently, making sure that their poor pupils don't act out in class?
