Providing a Model for Replacing the Managers of Four Educational Districts of Karaj (mixed fertilization)

 The present study was conducted with the aim of providing a conceptual model of the succession of managers of the four education districts of Karaj.

 The method of the present research is in terms of practical purpose, in terms of data, it is a mixed exploratory type (qualitative and quantitative), and in terms of the nature and type of study, in the qualitative dimension of the data, it is a self-emerging foundation, and in the quantitative dimension, it is a cross-sectional survey. The statistical population in the qualitative part of the present study includes all experts in the field of human resources. The quantitative part, includes all the education managers of the four districts of Karaj city, in the number of 850 people (500 men and 350 women). The tool of the qualitative part is a semi-structured interview form, which was obtained with the help of open, central, and selective coding. In the quantitative part, after the theoretical saturation of the experts regarding the interview form of the qualitative part, the said form was converted into a questionnaire by attaching the indicators and implemented on the sample group that was randomly selected. The reliability and validity of the measurement tool were done in two parts: A- Qualitative part: The reliability and validity of the measurement tool in the qualitative part was obtained with the help of three-way consensus (consensus of data, consensus of researchers, and community of theories and methodology). B- Quantitative part: In the quantitative part, reliability is calculated with Cronbach's alpha, and its total value is equal to 0.98. Data collection methods - Qualitative part: It includes the following steps: 1- First, the researcher has studied all the theories, patterns, models, and research findings, both national and global. 2- He calculated the indicators of step 1 with the help of open coding. 3- Then he categorized the calculated indicators with the help of axial coding in the form of dimensions, components, and indicators. 4- At this stage, the categorized indicators were prepared in the form of a semi-structured interview form and provided to Delphi and brainstorming experts, and this process continued until theoretical saturation was reached. 5- Dimensions, components, and final indicators were prioritized, and drawn in the form of a pattern and finally validated by experts. The quantitative part: This part includes the following steps: 1- A saturated interview form was developed for experts by weighting the indicators. 2- The aforementioned questionnaire was implemented in the sample group that was randomly selected. 3- The answers of the subjects were manually calculated and then analyzed in the Lisrel software package with the help of the confirmatory factor analysis test. 4- In this way, first, the components and indicators were measured by the sample group. 5- Then the quantitative and qualitative stage was compared. The method of data analysis was carried out in two parts: A- In the qualitative part, the data was analyzed with the help of open, central, and selective coding (interview, Delphi, and brainstorming with experts). B- Quantitative part: It consists of the following two

1- Data description: In this part, conventional methods of descriptive statistics such as drawing descriptive tables, drawing statistical characteristics, and drawing diagrams were used. 2- Data analysis: In this section, so-called confirmatory factor analysis tests were used. The data analysis of the current research was done in two parts, in the qualitative part, this part was done in four stages: A: Open coding: In this stage, 50 indicators were counted by the researcher with the help of global national studies and interviews with informants. B: Axial coding: At this stage, 69 indicators were counted by the researcher in the form of 11 components and 3 dimensions with the help of interviewing the informants. It should be noted that to avoid the confusion of the text of the article, the mention of the open and axial coding table has been avoided. C: Selective coding: In this stage, which was done by the experts, in total for the succession model of the managers of the four education districts of Karaj, in order of priority, 3 dimensions, 13 components, and 75 indicators which are given in table (2) for the succession model of the managers of the four education districts of Karaj city It was finalized.

 As a result, the research findings in the quantitative part confirm the results of the qualitative part. In this way, all the sample people confirmed the findings obtained in the qualitative section. It should be noted that during this process, interviews, Delphi technique, and brainstorming were used. In the quantitative dimension, the saturated form was applied by the experts by giving weight to the indicators based on the criteria extracted from the qualitative stage, the Weber-transformed five continuum questionnaire on the sample group. were randomly selected and implemented. The validity of the measurement tool was measured and confirmed by CVR (CVR) and its validity by Cronbach's alpha. Data analysis was used in the quantitative section in descriptive statistics (drawing tables, statistical characteristics, and graphs) and inferential statistics (confirmatory factor analysis, T-test, one-way analysis of variance, and also K-S test to ensure the normality of the research population). The research in the qualitative part showed that the mentioned model consists of three dimensions in the order of priority: 1- the dimension of individual competencies 2- the dimension of managerial skills - the dimension of talent management, 13 components and 75 indicators were finalized. In the quantitative part, the indicators of AGFA, GFI, RMSEA, and two all indicate that the dimensions identified in a homogeneous structure support the structures of a concept model under the title of a conceptual model of a succession of managers of the four educational districts of Karaj city.

 Based on this, the current research aims to provide a suitable model for the succession of directors of the four education districts of Karaj City, and in this way, this model can be used as a practical guide for the establishment of the succession program in this ministry and other government ministries and educational organizations. Be used similarly.
