The research instruments included demographic information form capturing gender, age, level of education, years of working background, and a researcher-made questionnaire ( 50 items), whose face validity was confirmed based on expert opinion, while its reliability was calculated using Cronbach alpha method on 30 staff as 0.95. The data were analyzed by exploratory factor analysis and structural equations modeling methods in SPSS-25 and Smart PLS-3 software.

The statistical population of the study was the principals of public primary schools in Tehran in the academic year of 2019-2020. In two stages of sampling, samples were selected by quota and then purposive sampling methods. Semi-structured interviews were used to collect data. The interview continued until the data exploration and data collection process reached a theoretical saturation point after interviewing 14 people. Data were analyzed by open and axial coding steps. Two methods of verifying the interviewees and verifying an external expert were used to control the validity. Two methods of verifying the interviewees and verifying an external expert were used to control the validity. To determine the reliability, two methods of reviewing the writings and also the method of recoding were used. The agreement was calculated in the coding homogeneity and the agreement coefficient was 86%. Findings showed that the professional development framework for primary school principals has 3 dimensions, 14 components with 117 indicators  Which includes : the content dimension of professional development (with components of general management knowledge, specialized management knowledge, interactive skills, resource management skills, professional skills, personal inclinations, managerial attitude, physical and mental ability and intellectual ability), the dimension of professional development process (with the components of self-development actions and developer relations) and the dimension of organizational requirements (with the components of knowledge acquisition and acquisition of skills, modification of selection and appointment methods of managers, improvement of organizational structure and processes).
