We call it collaborative efficacy. Marzano referred to collective efficacy. Students call it, "Everyone on the same page." At Catholic Central High School, we strive to create and maintatin a culture where staff rely on each other for instructional advice, share cross-curricular ideas and recognize the value of shared leadership. Results from a School Social Network analysis indicate that we have a strong collaborative culture that benefits student learning. In this presentation, we will share some of the strategies the administrative team has put in place to achieve these positive results.
