Meta-analysis of transformational school leadership effects on school outcomes in Taiwan and the USA

Researchers have suggested that transformational leadership is an important aspect of effective schools; however, whether the effects vary across related studies and the robustness of the overall effect size remain unclear. A meta-analysis technique was used to synthesize the results of 28 independent studies and to investigate the overall relationship between transformational school leadership and three measures of school outcomes. The study found that, in terms of the mean effect sizes, transformational school leadership does have positive effects on teacher job satisfaction, school effectiveness perceived by teachers, and student achievement.
