This article describes certain aspects of human resources functioning evaluation within organizations. Through human resources functioning evaluation we try to see what the contribution of the human resources department is, in order to accomplish the organization's objectives. The human resources department contribution may be determined as a result of applying more criteria, both quantitative and qualitative, that are grouped into more categories: organizational criteria, employees' behaviour criteria, criteria referring to the human resources department performance level, user's reaction appreciation criteria and employees' satisfaction criteria.
