The enduring existence of disproportionate representation of students from culturally and linguistically diverse backgrounds in special education programs and disciplinary practices creates a double bind for educators, educational leaders, and families. Disproportionality is an adaptive systemic issue that is not under any entity's control; thus, it demands collaboration and critical dialogue among local stakeholders. This article examined the implementation of Learning Lab, a new methodology of systemic transformation, for local stakeholders to collectively examine and address disproportionality in behavioral outcomes from the ground-up. Learning Lab aims to increase equity within the local implementations of Positive Behavioral Interventions and Supports (PBIS) by opening up decision-making and problem-solving processes with local stakeholders. Designed to increase authentic collaboration and dialogue among educators, families, and community-based organizations, Learning Lab offers the possibility of contextually fit, culturally responsive implementations of PBIS and building the capacity for forming adaptive and inclusive schools.
