Data collection methods in this study were divided into two categories: library and field. In this study, an expert questionnaire was used to collect research data. In order to estimate the validity of the questionnaire, after calculating the CVR, the number 0.62 was obtained, so it was found that all the questions of the questionnaire had the necessary validity. Findings: In the model obtained in the present study, priority consists of 3 dimensions, 13 components and 52 indicators, respectively. Dimensions of research Developing a model of human resource training based on the rotation of brains in the educational system and presenting a model that is considered and deals with the main structure of the research to achieve the desired result and what was the motive and causes and effects of the components of this elite movement process. . These dimensions are: 1- Effects of pattern on elite migration 2- Factors of elite migration 3- Motivation of model providers to intervene in elite migration.
