This document summarizes an online administrator mentor roundtable on school culture and transformational change. It provides an agenda for the roundtable, including introductions, norms for collaboration, a discussion of how the topic relates to participants' current roles, objectives, and a discussion of key aspects of school culture like defining culture, different culture types, and using a school culture typology worksheet. It also discusses transformational change through triple-loop learning and provides a scenario for participants to discuss how to address a principal struggling with cultural resistance to changes. The document aims to help administrators examine and potentially transform their school's culture.
