This study is an attempt to examine the psychometric properties of the academic engagement scale formulated by Tinio in 2009. The academic engagement scale was administered to a sample volume of 358 students who were randomly selected thorough the process of cluster sampling. The construct validity, convergent validity and internal consistency of the scale were calculated by exploratory factor analysis, confirmatory factor analysis, Pearson's product-moment correlation coefficient and Cronbach’s alpha coefficient. The results of principle component analysis and oblique rotation demonstrated that the academic engagement scale had three factors. The goodness of fit indices of confirmatory factor analysis also confirmed the three factors. Moreover, the multidimensional scales of academic engagement scale were shown to be an acceptable measurement model in this sample. The correlation coefficients between academic engagement subscales were positive and significant (p<0.05), which confirmed the convergent validity of the scale. Regarding the internal consistency, the alpha coefficient was calculated as 0.96, behavioral engagement as 0.90, emotional engagement as 0.92 and cognitive engagement as 0.88 of the total scale. In conclusion, Tinio's scale was proved to be a valid and reliable instrument for measuring THE academic engagement of the Iranian students.
