Ability--Testing; Grading and marking (Students)


This study was conducted to determine if the tests of Verbal Reasoning and Abstract Reasoning of the Differential Aptitude Tests could be used in the prediction of grade point average after the freshman, sophomore, and junior years at Central High School, Burlington, Illinois. A second purpose of the study was to add to the information available about Central High School. In the investigation the scores of the two tests were correlated separately with the same students' grade point averages for the freshman, sophomore, and junior years. Each correlation was checked for its percent of efficiency as a predictor of academic success. A review of the literature revealed studies which supported the effectiveness of the Differential Aptitude Tests in predicting academic success. The results of the Verbal Reasoning Test were shown by several studies to be the best indicator of success. The study was limited to a sample of 127 students who were enrolled in eighth grade, and who had attended Central High School. The correlations were 0.493, 0.523, and 0.415 between the Verbal Reasoning Test and freshman, sophomore, and junior grade point averages. The correlations were 0.495, 0.512, and 0.415 between the Abstract Reasoning Test and the three grade point averages. Further investigation is needed into the relationship between the Differential Aptitude Tests' results and grades achieved in individual subjects at Central High School. A study which separates the sexes would also be of benefit. Because of the unexpected findings of this study involving the Abstract Reasoning Test' a further study of the scores achieved by Central High School students on the Abstract Reason­ing Test could be undertaken.
