Interplay between leadership and school-level conditions: A review of literature on the Teaching and Learning International Survey (TALIS)

We combined network analysis and meta-analysis to systematically review the literature on the Teaching and Learning International Survey, focusing on the interplay between leadership practices and school-level conditions. Our initial network analysis utilized 83 nodes (variables in the reviewed studies) and 214 ties (variable associations), whereas our subsequent meta-analysis employed 21 selected variable associations. Results suggested that leadership practices interplayed with school-level conditions through multiple, interconnected variable associations with a range of effect sizes. First, variables concerning teacher working conditions and teacher qualifications indicated relatively smaller effects than teacher self-efficacy. Second, the association between teacher self-efficacy and teacher collaboration indicated the strongest effect among other variable associations, followed by the relationship between collective teacher perceptions of distributed leadership and teacher job satisfaction. Third, variables regarding teacher perceptions of the principal's leadership effectiveness had larger effect sizes than the principal's self-assessment of their leadership practices. Results further suggested teacher self-efficacy and teacher collaboration as the two most prominent variables that would potentially play a bridging role between leadership practices and school-level conditions. We provide implications for educational leadership practices and research.
