This study aimed to examine the influence of conflict, leadership, organizational culture, and work ethic on employees' work performance in North Sumatra Education Authority, Indonesia. This becomes important because this organization is not a profit-oriented organization, so it needs further understanding about how to foster the work performance. However, most of these research topics still concentrate on the western populations. A quantitative approach was used to conduct this study, where data were collected directly to the office of Education Authority with n = 180. Partial Least Square Structural Equation Modeling (PLS-SEM) is employed for data analysis in this study. The results showed that conflict negatively affects employees' work performance. However, leadership, organizational culture, and work ethic have positive effect on employees' work performance.

This paper aims to identify the development of the quality of Human Resources in improving the quality of educational institutions. The results of the study indicate that efforts to guarantee and improve the quality of education, especially human resources, are difficult to separate from quality management, where all management functions carried out are directed as much as possible to provide services that meet or exceed national education standards. In this regard, efforts are needed to control quality through optimization as illustrated by a good and systematic Standard Operating Procedure (SOP), and supported by an organizational culture that continues to evolve towards improvement.
