This study examines educational inequalities between boys and girls in secondary schools by using context, space, human resources, education coverage, education process, outputs and outcomes as comparative indicators. The research study is a descriptive - analytical survey. The required data have been collected through both using documents and questionnaires. Using stratified random sampling, the questionnaires were distributed among a sample of 815 high school students (419 boys and 396 girls) in province of Western Azerbaijan. Validity of questionnaires has been confirmed by using factor analysis and reliability by using Cronbach’s Alfa. The findings suggest that in the context of inequality, except for educational sensitivity of parents no other variable showed a significant difference between boys and girls. Given the disparity in the space, human resources and educational coverage indicators,, a significant inequality is evident between boys and girls. As to the question of inequality in educational processes, apart from inequality in the justice treatment, there is no significant difference between boys and girls. For the question of inequality in outputs and outcomes, the educational success of female students as well as their higher percentage of passing the university entrance and developed motivation toward school, shows higher status of girls.
