Schoolwide Positive Behavior Support, a framework for remediating and preventing student problem behaviors and supporting schools, has demonstrated a reduction in office disciplinary referrals (ODRs) among student groups. However, African American students are still overrepresented in ODRs. This study extended a prior study that explored parents' perceptions of schoolwide expectations. The previous study resulted in the development of a social skill curriculum to embed parental input within the meaning of the expectations as one way to build cultural responsiveness. Specifically, authors aimed to examine the effects of the social skill curriculum on the nonadherence to classroom expectations of K-1 African American students' using multiple-probes across participants design. Results indicated improved adherence to behavioral expectations across participants. Implications for research and practice are provided.
