Then the effect of transformational leadership and mediateing variables on academic achievement and also goodness of fit indexes of hypothesized and 5 alternative models were analyzed. Results demonstrated indicated that hypothesized and 3 alternative the initial models did not dont have good fit with observed data. After developing the final model, all of direct, indirect and total effects were found to be significant. This model has showed good fit with observed data and explained 0.32 of variance of academic achievement. In general, the results indicated that academic achievementtransformational leadership of principal hads significant indirect effect on academic achievement and attention to the role of mediating variables is crucial.
