This one is being cited- lots of statistics- but, more evidence- of the connection between academics and disipline-makes the case for both the science of reading, PBIS, and evidence-based interventions that are culturally responsive important for addressing disparities.

We also found evidence that the association between the Black-White achievement gap and the Black-White discipline gap was attributable, in part, to the tight coupling of achievement and discipline for Black students in particular, who experience higher suspension rates in districts with larger achievement gaps and who experience higher achievement in districts that suspend them less frequently. Notably, this tight coupling of discipline and achievement was not observed for White students. This pattern indicates that the mechanisms connecting achievement and discipline (e.g., teacher biases, peer effects, feelings of belonging) are more salient for Black than White students.
