Studies indicate that many students engage in procrastination, thus in this study the aim was to examine the structural relationship of early maladaptive schemas and academic procrastination with the mediating role of the perfectionism in students. The participants included 281 high school students (143 male, 138 female) that were chose by multistage cluster sampling method. Solomon and Rothblum's academic procrastination scale with the Cronbach alpha coefficient 0.81 and Young early maladaptive schema questionnaire with the Cronbach alpha coefficient 0.93, and Positive and Negative Perfectionism questionnaire with the Cronbach alpha coefficient 0.86 were administered. Structural Equation Modeling (SEM) and Sobel tests were conducted to explore direct and indirect pathways of study's model respectively. Results showed that early maladaptive schemas and academic procrastination are antecedents and consequences of perfectionism in students respectively. The results indicated that perfectionism has a significant mediating role on the relationship between early maladaptive schemas and academic procrastination. The findings of this study could help school counselors, education psychologist, and teachers to reduce student's procrastination and academic problems.
