The self-esteem of each individual affects a person’s behavior, and it is important for daily living. The objectives of this study were 1) to investigate the fit of the self-esteem measurement model for ethnic students to the empirical data, 2) to test the measurement invariance of the self-esteem measurement model across diverse ethnic groups of students, and 3) to compare the extent of self-esteem of ethnic students across their backgrounds. The participants were 688 ethnic high school students who were studying in the second semester of the academic year 2018 in four provinces . The instrument of this study was the 5-rating scale questionnaire with Cronbach’s alpha reliability coefficients ranged from 0.90 to 0.95. Data analysis was done by descriptive statistics, interential statistics and structural equation modeling. The results revealed that 1) the theoretical measurement model fitted the empirical data with acceptable fit indices (p = 0.14, CFI = 0.99, RMSEA = 0.04, SRMR = 0.01). 2) the measurement model of the self-esteem was for different groups of ethnic students, was invariant in terms of measurement error and 3) the comparison of the self-esteem levels of ethnic students across backgrounds indicated that the scales of satisfaction of self-ability, family, and society had statistical significance at the level of .05.
