The statistical population consisted of MSc students in College of Agriculture and Natural Resources, University of Tehran (N=712). According to Cochran formula, 175 students were selected through quota sampling method. The instrument for data collection was a questionnaire which its validity was confirmed by a panel of experts. Its reliability was confirmed by Cronbach's alpha coefficients (α ≥0.7). The results of descriptive statistics showed that the amount of achievement motivation, global self-esteem, family self-esteem and social self-esteem found to be at a moderate level, whereas their educational self-esteem was found to be at a low level. The results of ANOVA showed that there are significant differences among students based on their levels of self-esteem and achievement motivation. Students with higher levels of self-esteem had achievement motivation more than others. Moreover, the results of logistic regression demonstrated that different aspects of self-esteem (including global self-esteem, social self-esteem and educational self-esteem) has a great ability to predict levels of students' development. These factors explained 69.10 percent of the total variance.
