John Hattie’s research tells us that collective teacher efficacy has the highest effect size on student achievement. When educators come together consistently, share best practices, break down data, and put a plan together to impact student success it’s a good thing (HATTIE, J. 2017). Our four integration specialists design, deliver and sustain high quality, hands-on professional development that aims to increase staff efficacy and proficiency in being able to align best practices in Positive Behavior Interventions and Supports (PBIS), Response to Instruction and Intervention (RtI²), and Multi-Tiered System of Support (MTSS) with an emphasis on culturally relevant pedagogy and the development of cultural competency.
