A study examined whether ACT subtest scores can be used to predict reading skills, as measured by the Nelson-Denny Reading Test, with a degree of accuracy that would support their use as a screening device for college placement. ACT test scores of 2,431 students were used to predict Form C Nelson-Denny raw scores. ACT test scores from 3,016 students were used to predict the Form E Nelson-Denny raw scores. To achieve clarity and accuracy of prediction, separate analyses were conducted for each form of the Nelson-Denny Test. The results indicated that reading skill, as measured by the Nelson-Denny Reading Test, can be estimated with a moderate degree of accuracy by using the ACT Social Studies Reading and ACT English Usage subtests. In addition, the established statistical relationship between the Nelson-Denny and ACT tests suggests that if the ACT tests are used initially for college placement or course predictions, it is doubtful that the addition of Nelson-Denny test data would result in substantive improvement in the prediction.
