Nowadays, there is an agreement among organizations that reinforcing of education leads to the improvement of organizational performance. The emphasis on the human capital in organizations reflects the view that market values depend less on tangible resources, but more on intangible ones, particularly human resources. The main purpose of this study was to design a model for faculty members in public Agricultural Higher Education in Iran. A survey method was used to collect data from nine Public Agricultural Faculties in Iran. Samples were collected from faculty members using a simple random sampling method (n=284) and a questionnaire was used as the main research instrument to collect data. Reliability and validity were calculated using Structural Equation Modeling through LISREL software, version 8.54 (above 0.7). Finally, a model was developed and tested for faculty members in Agricultural Higher Education System in Iran. The findings showed that contextual variables (i.e. personal, organizational, social, educational, and professional development) had direct impacts on the process of Human Resource Development (HRD). Furthermore, personal and organizational development had direct and indirect impacts on HRD (R 2 = 0.70).
