This report outlines the development of the Hogan Competency Model (HCM) and describes how the Hogan Research Division uses the model to conduct personality-related research. The HCM has three advantages. First, we designed the model to have minimal overlap between competencies, allowing us to better measure specific behaviors. Second, we designed competencies to target specific areas of performance. In contrast, many models target several behaviors with a single competency. This lack of specificity contaminates measurement and subsequent prediction of the competency. Finally, our development process centered on a review of twenty-one competency models used across academic, commercial, and government settings. This both assures that the model is comprehensive and that it can be easily compared to and used in conjunction with other competency models.
