Abstract

The primary purpose of this study is to examine the relation between academic performance of college students and score of biodata inventory that consists of Owen`s Biographical Questionnaire(1976) and the biographical questionnaire for prediction of job performance developed by Lee(2001). The second purpose is to verify the stability of validity when the same biodata items and item weighting system were applied to freshmen after one year. Eight hundred sixty seven cases were used in the item analyses and validation study and 865 cases were used in cross-validation study. Based upon the relationship of biographical items and academic performance, 26 items among 86 biographical items were selected. The validity of empirically keyed biodata(WAB weighting system) was .59, which was higher than the validity of the National Academic Aptitude Test and the high school records. When weight yielded from this was applied to 865 freshmen(cross-validation group) after one year, the biodata was considerably stable in validity and had higher validity than other selection tools.
