The present study aims to present an educational model for the development of the staff of the National Organization for Civil Registration. The research method was mixed (qualitative and quantitative). The data collection tool in the qualitative part was a semi-structured interview, and in the quantitative part, a researcher-made questionnaire on staff development was used. The reliability of the questionnaire was calculated through Cronbach's alpha. The results of these interviews were a set of initial themes that were gathered through the coding process, from which categories were extracted. Then, in the axial coding stage, the connections between these categories were determined. For analysis, structural equation modeling was used, and to determine the current situation, one-sample t-test was utilized. For comparing the current and desired situation, one-sample t-test was employed through SPSS24 software. For presenting the final research model, measurement modeling was used, and for fitting the model in the structural equation modeling technique, PLS3 software was used. The findings of the qualitative part of the research led to the identification of two dimensions (individual and organizational). The organizational development dimension consisted of 8 components, and the individual development dimension consisted of 3 components, which included 19 themes (sub-components) for assessing the mentioned components. The current situation of staff development in the National Organization for Civil Registration showed a gap and distance in the organizational development dimension, while there was no gap and distance in the individual development dimension between the current and desired situations. Based on the research results, the components and indicators were identified, and the final model was drawn. The developed model can serve as a guiding charter for the macro-level planning of managers and planners of the National Organization for Civil Registration.
