The purpose of the present research is to explain and design the model of internal factors of strategic human resource planning based on the recruitment and adjustment of knowledge-based employees in the National Development Fund. The research method is descriptive-survey. The statistical population consists of two groups, the first group includes experts familiar with the theories of strategic human resource planning and the recruitment and adjustment of knowledge-based employees, whose number is unspecified and have been scattered throughout the country and their selection method is selective and in this research their opinions have been used in the section of compiling and designing the model, and the second group includes knowledge-based employees (having university education) of the National Development Fund (2,115 people) that 325 people were selected as sample based on Cochran's formula. In the field of data collection, the questionnaires of internal factors of strategic human resource planning, knowledge-based employees, recruitment of knowledge-based employees and adjustment of knowledge-based employees were used whose validity were 0.91.5, 0.94.9, 0.93.8, 0.92.1, and their reliability were 0.86, 0.99.1, 0.94.6, 0.90.2 respectively. Data analysis was performed using structural equation modeling by applying LISREL software version 8.8. The results showed that there was a significant relationship between the internal factors of strategic human resource planning including (organizational goals, skill level, employees' efficiency, organizational structure, job satisfaction, organizational culture, organizational value, and organizational mission) and the recruitment of knowledge-based employees in the National Development Fund.
