This study adopted questionnaire survey as the research method and adopted stratified random sampling as the sampling method. The research subjects were 367 teachers serving in public vocational and senior high schools in Kaohsiung City. This study used methods, such as descriptive statistics, t test, ANOVA, product-moment correlation, and multiple stepwise regression analysis, to perform analyses. The results are as follows: (1) For the overall principal service leadership perceived by teachers, “care and communication” was the highest; for teachers’ job involvement, “job identity” was the highest; for school effectiveness, “teachers’ professional quality” was the highest (all were moderate and above); (2) the overall current status of principal service leadership, teachers’ job involvement, and school effectiveness varied with age, post, school scale, and gender of principal; (3) there was a low to moderate positive correlation among principal service leadership, teachers’ job involvement, and school effectiveness; (4) principal service leadership and teachers’ job involvement both could predict school effectiveness; the predictive power of “shaping vision” and “job identity” was the highest; (5) principal service leadership could further positively predict school effectiveness through the partial intervening effect of teachers’ job involvement.
