Abstract

This study was conducted to whether the biodata of undergraduate students could predict academic achievement and satisfaction of school life. A Biodata Scale, comprised 76 items, was administered to 807 university students to extract 17 items predicting academic achievement and 33 items predicting satisfaction. Results of cross validity indicated that when the WAB method is applied, the correlations between items and academic achievement and satisfaction were significant in both developmental and validity group. When Factor Scaling method is applied, validity coefficient of developmental group was decreased and stability of validity was increased in predicting academic achievement than WAB method. But validity coefficient of both developmental and validity group was decreased on prediction of satisfaction. Finally, the implications and limitations of this study were discussed and the future directions of study were suggested.
