This study aimed to develop a conceptual model of the role of organizational support in moderating the effect of competence and organizational commitment on management performance. The population was 150 managers of the National Sports Committee of Indonesia in the city, regency and province of Riau. The entire population was sampled and the data was processed using Structural Equation Modeling Partial Least Square (SEM PLS). The study found that competence and organizational commitment have no effect on management performance and organizational support acts as the moderator of the effect of competence and organizational commitment on management performance. Organizational support is a pure moderator that amplifies the effect of organizational commitment on management performance.
