This study uses the confirmatory factor analysis technique to determine whether the number of factors and loads of variables measured on these factors are consistent with what is specified in the theory. According to the results of confirmatory factor analysis, the standardized coefficients are acceptable and relatively large. Through the SEM structural model, it was estimated that the highest correlation and consistency between subjective factor with factor loadings of 0.76 and physical component rank second. With a factor load of 0.63 and finally the educational component with a standard coefficient of 0.58 establishes and promotes a sense of  belonging in high schools.
