Designing and validating Principals’ Effectiveness Model in high schools

The aim of this study was to design and validate school principals’ effectiveness model at high schools in Lorestan Province, Iran. The experts and specialists were selected through theoretical saturation and the principals (n= 199; 102 men and 97 women) were selected through cluster random sampling method. Data analyses were done in SPSS and LISREL and data validity was confirmed by experts. As for reliability, Cronbach’s alpha was obtained equal to 0.96. Normality of the study population was measured using skewness test and data analyses were through structural equations and path analysis. The results showed that Chi square test (df=2.46) was less than 5, which supports goodness of fit of the model. Therefore, the elements of school principals were significant at 0.99 level and properly confirmed the effectiveness variable in the proposed conceptual model.
