This study examines the structural relationships among learning‐organization culture, self‐efficacy, work engagement, and job performance in Korean workforce institutions. The authors also investigated the mediating roles of teachers’ self‐efficacy and work engagement on the relationship between the learning‐organization culture and teachers’ job performance. Working with a total of 481 valid surveys from workforce‐education teachers at 21 Korean workforce‐education schools, structural equation modeling (SEM) and the Sobel test were primarily implemented to examine the hypothesized model and research hypotheses. The results showed the positive impacts of learning‐organization culture in Korean workforce institutions on teachers’ self‐efficacy and work engagement. Teachers’ self‐efficacy positively affected their work engagement and job performance, and the relationship between work engagement and job performance was statistically significant. Also identified were the mediating roles of self‐efficacy and work engagement on the relationships between the learning‐organization culture of workforce‐education schools and the teachers’ job performance.
