The effectiveness of a leadership team is central to the overall effectiveness of the school. Leadership teams that collectively attend to actualizing instructional goals, building relationships and developing the culture of the school often find success in their efforts (Leithwood et al., 2020). However, some leadership teams struggle to develop this concerted level of organizational cohesiveness. This study investigated how teacher leaders' organizational cohesiveness supports the instructional goals of the school. Findings highlight how the team's struggles were rooted in school leadership dynamics, unresolved priority differences and ambiguity in roles and responsibilities.
