Guest School Psychology Review (SPR) editors, Jessika Bottiani, Catherine Bradshaw, and Anne Gregory discuss some of the key findings in their SPR Special Issue “Closing in on Discipline Disproportionality,”. They delve into the promising approaches and critical challenges to closing racial and ethnic gaps in schools’ use of exclusionary and punitive discipline practices. They emphasize the need to catalyze scientific rigor in the next generation of evidence-based interventions to close the discipline gap and why this matters to outcomes for students.
