Introduction: Understanding the sources and the effects of collective teacher efficacy has been one of the central interests to many educational researchers and practitioners, because it is critical to understand how teachers can shape, and are shaped by, the educational processes in schools. Following the social cognitive perspective on the sources and consequences of efficacy beliefs, this study examined how school support influences collective teacher efficacy which in turn affects teachers’ organizational commitment. Method: The participants included 969 teachers sampled from 28 primary and secondary schools in Hong Kong. To appropriately address the nature of collective teacher efficacy and school support as school-level variables, the doubly latent multilevel structural equation modeling approach was used to analyze the data. Results: The results revealed the mediation mechanism played by collective teacher efficacy in explaining the effect of school support on teachers’ organizational commitment. Discussion: Schools are suggested to consider fostering a supportive school environment as a strategy to improve teachers’ collective efficacy beliefs if it is wished to enhance teachers’ commitment to schools. Copyright © 2023 Zhang, Lee, Yin and Yang.

This study attempted to identify communication as a human relational 'path' through which principal leadership influenced teacher professional learning. The data was collected from a sample of 970 teachers from 32 Hong Kong primary schools. Online survey was administered, with two questionnaires to measure teacher perceptions of principal leadership and school capacity. Baron and Kenny' s (1986) four-step causal process for mediation analysis was employed and integrated with bootstrapping method. Further significance of the mediating effects of communication was tested, and the sizes for both the direct and indirect effects in the relationship were made explicit. The findings affirmed the role of communication as a mediator in the relationship between principal leadership and teacher learning.
