This study investigates how learning-oriented school cultures, conceptualized through the Schools as Learning Organizations (SLO) framework, relate to teacher self-efficacy, job satisfaction, and work effectiveness in primary schools within a centralized education system. While these constructs have received considerable attention in the literature, they have rarely been examined together within a unified organizational learning perspective, particularly in contexts marked by limited school autonomy. Using a cross-sectional survey design, data were collected from 94 teachers in nine public primary schools, alongside aggregated student ratings of instructional effectiveness from 364 pupils. The findings showed that learning-oriented school cultures were positively associated with teacher self-efficacy, job satisfaction, and work effectiveness. Teacher self-efficacy also partially mediated the relationship between SLO conditions and both job satisfaction and work effectiveness. These findings indicate that learning-oriented school cultures may strengthen teacher outcomes directly and indirectly by reinforcing teachers’ sense of efficacy. Thus, the role of school leadership in cultivating collaborative and inquiry-oriented professional environments is particularly important
