This document discusses the concept of "non-discussables" in schools. Non-discussables are important issues that everyone is aware of but avoids openly discussing due to anxiety and fear. Each school has its own non-discussables, such as poor leadership, decision-making processes, or underperforming teachers. By avoiding these issues, schools give problems license to continue. To change school culture, instructional leaders must enable open discussion of non-discussables to address issues impeding learning.
