This national report represents the first major effort to fill the knowledge gap around school discipline and suspension rates. The researchers find that the frequent use of suspension brings no benefits in terms of test scores or graduation rates. Thus the oft-repeated claim that it is necessary to kick out the bad kids so the good kids can learn is shown to be a myth. They conclude that a relatively lower use of out-of-school suspensions, after controlling for race and poverty, correlates with higher test scores, not lower.
