Evidence of Construct Validity for New TEPS

The purpose of this study is to obtain evidence of construct validity for the revised TEPS. Multiple data sets were obtained from the operational TEPS administrations before and after the revision and four pilot tests during the revision process and used for correlation analysis and confirmatory factor analysis. Inter-section correlation coefficients and standardized factor loadings were compared across forms, and the model-data fit indices were examined for each form. Based on the results, it was found that the original TEPS and the revised TEPS measured very similar or virtually the same construct. Even though the revision introduced major changes to the TEPS, the underlying factor structure was the same for all the forms examined in this study.
