The aim of this study was to identify the dimensions and components of administrators decision making in educational organization. This research method was a mixed exploratory research. The statistical population in the qualitative section included all school principals in Tehran and expert principals of educational system and the sampling method was purposeful and theoretical. In quantitative part, the statistical population was all school principals in Tehran, which according to Cochran's formula, the number of sample members was 249. Data collection tool in the qualitative part of the interview was semi-structured and retesting and reliability between the two coders were used to check the validity and reliability of the interviews and coding, and they are approved as 0.75 and 0.77 respectively. The collection tool in the quantitative part was a researcher-made questionnaire that its validity was checked and confirmed by content validity method and confirmatory factor analysis. The reliability of the instrument was evaluated and confirmed using Cronbach's alpha method, and it was approved as 0.625. Grounded theory approach was used to analyze the data in the qualitative part. One-sample t-test, Pearson correlation coefficient and confirmatory factor analysis were used to analyze the quantitative part. The findings showed: 1- Dimensions of decision making were classified into eight categories: knowledge, experience and expertise, ethical, psychological, social, human, technical and economic. 2- There was a significant correlation between the dimensions and components. 3- Knowledge dimension and psychological dimension had the highest and lowest mean, respectively.

Objective: The purpose of this study was to identify the weight of each of the courses of academic record and scoring based on the psychometric approaches of factor analysis and the continuous IRT model and the approaches based on the viewpoint of the experts of Topsis and AHP, as well as the comparison of the effect of the weighting model on variance and the predictive validity of the scores. Methodology: The method of this study was a mixed research method. In order to conduct research in the first part, 11 items (courses) of academic background were taken from the expert group and weighed and prioritized using Topsis and AHP techniques. In the second section, the final third year high school grades of volunteers and admitted students of psychology and counseling at universities across the country were received from the Sanjesh Organization for estimating standard weights in the form of factor analysis and calculating Theta. In the third section, in order to compare different weighing and scoring models, the sample group was firstly scored based on scores derived from all four approaches, and compared in terms of dispersion indexes and predictive validity. Results: The results of the comparison of the four approaches showed that the most variance is related to the IRT continuous modeling method. Also, the results of the data analysis showed that the scores obtained from the continuous IRT model had the highest correlation with the university's average score and the psychology score of the Konkoor. Conclusion: The comparison of the frequency distribution of the score-ability in the framework of all four approaches indicates that the abundance distribution in the IRT encompasses a wider range of abilities and more variance, and also results in higher predictive validity Has enjoyed. Based on this, it seems that with enough information, the test scoring framework can be changed to the theta scores that have a higher predictive validity and higher detection capability.

Concerns have been made about the personality characterize indices after the appearance of personality tests. In this regard, the aim of the present study was to compare the relationship between personality traits and social desirability in students with honest and faking responses. The present study was a causal-comparative study in which 235 students completed the research questionnaire. Subjects were randomly assigned into two groups: honest and faking. To collect the data in this study, NEO's personality questionnaire (1992) and social desirability scale by Crown and Marlow (1960) were used. The findings showed that there is a relationship between personality dimensions and social desirability, and this relationship is not meaningful between the two groups. Therefore, we can say that we must propose methods for controlling the probabilistic effect of social desirability in studies with a five-factor personality model.
