A study investigated the results of the use of Form E (Vocabulary and Comprehension subtests) of the Nelson-Denny Reading Test (NDRT) with six successive cohorts of freshmen entering a midwestern state university. The purpose of the study was to determine the relationships existing between NDRT scores and other indicators of academic success such as high school and college grade point average (GPA), rank in class, American College Testing Program scores (ACT), and Scholastic Aptitude Test (SAT) scores. Although 11,953 subjects were tested, only the data collected from 7,635 currently enrolled students were used to form the basis of the analyses. Results revealed that NDRT scores correlated positively with ACT Composite scores, with SAT Verbal scores, and to a lesser degree with college GPA and high school GPA. Also, NDRT scores added no predictive value to equations already containing high school grades and SAT or ACT scores. Finally, the Vocabulary test of the NDRT-E exhibited effects of speed, and neither the Vocabulary nor the Comprehension tests proved to be "power" tests, i.e., neither one was likely to provide much diagnostic value as subscores.
