The aim of this study is to investigate the effect of educational management on students' academic success, teachers' job satisfaction, school efficiency, and parental interaction in schools in the Kianparsh region of Ahvaz city. The present study is applied in terms of its purpose and is a correlational research. Its statistical population includes students, teachers, and parents of secondary schools, of whom 320 people were selected as samples using stratified random sampling. The data collection tool was structured questionnaires with a five-point Likert scale, and their reliability was confirmed by Cronbach's alpha coefficient between 0.85 and 0.9. SPSS software was used to analyze the data. The research findings showed that educational management has a positive and significant correlation with students' academic success (r = 0.65), teachers' job satisfaction (r = 0.6), school efficiency (r = 0.7), and parental interaction (r = 0.55) (Sig < 0.01). Multivariate regression also showed that educational management is able to explain 42% of the variance in academic achievement, 36% of the variance in job satisfaction, 49% of the variance in school efficiency, and 30% of the variance in parental engagement, respectively. Also, the ANOVA test confirmed that there is a significant difference between different levels of educational management and dependent variables (Sig < 0.001). These results indicate that educational management plays a key role in improving academic performance, job satisfaction, school efficiency, and parental involvement. Therefore, it is suggested that educational administrators and policymakers create an optimal learning environment for students by implementing targeted management programs, improving teachers' professional skills, and encouraging parental involvement.
