The population consisted of five to six-year-old children in the preschool stage in District One of Tehran during the academic year 2021-2022. The sample size was selected based on Cohen's table with an effect size of 0.5 and a test power of 0.8, equaling 15 participants for each group. 30 children who met the entry criteria were identified and randomly replaced in two control and experimental groups. Participants completed such computer-based tests as Hungry Donkey Task, Tower of Hanoi, Continuous Performance Test, and N-Back Spatial Working Memory.

(2021) coaching leadership questionnaire as well as, the researcher-made questionnaire of lean behaviors of school principals were used. The reliability and validity of the questionnaires were investigated with Cronbach's alpha techniques, content validity ratio, exploratory factor analysis and confirmatory factor analysis. In order to analyze data and test research hypotheses, correlation matrix analysis and structural equation modeling were used with SPSS.v25 and LISREL.v10 software. The results indicated that: 1) the four types of organizational culture (involvement, adaptability, mission and consistency) had a direct, positive and significant effect on the lean behaviors of school principals 2) the four types of organizational culture had an indirect, positive and significant effect on the lean behaviors of school principals through mediating role of their coaching leadership. 3) Four types of organizational culture and coaching leadership of school principals estimated 59% of the variance of their lean behaviors.
