The purpose of this study was to investigate psychometric properties for Jordanian version of behavior assessment system (teacher & parents versions). An available sample of (739) teacher and a similar one from parents of students from grade four to grade seven were selected. Results showed that the item correlations with the dimensions which belong to, were moderate to high correlation. Also both Jordanian teachers’ and parents’ versions had a suitable matching of fitness indices when compared with the original version, with values of Comparative Fit Index (CFI) equal to (0.902), and a value of (RMEA) equal to (0.029).Furthermore, values of Tucker – Lewis Indices (TLI) were equal to (0.899), while incremental fitness of index was equal to (0.901), which means that all indices reflect appropriate values of fitness, as well as acceptable construct validity. Results also indicated that the parents\' version achieved appropriate values of fitness, as the value of (CFI) was greater than (0.90) and the value of (RMEA) equal to (0.001).Furthermore, values of Tucker – Lewis Indices (TLI) were equal to (0.989), while incremental fitness of index was equal to (1), which means that all indices reflect appropriate values of fitness, as well as acceptable construct validity.
