“Policies and practices that might be successful overall could actually help one group of students while harming another, so care should be taken when evaluating them to see whether they are benefiting all, some, or no students – and whom they are benefiting. Schools might do a better job ensuring success for all students the more they investigate how the practices are affecting different groups of students. We hope that this analysis will shed some light on possible policies and practices to be evaluated more rigorously, and to encourage a careful analysis of heterogeneous effects of policies and practices.” (more)
