The purpose of these studies was to provide information on the Dallas Preschool Screening Test (DPST). While the DPST is widely used in Texas, little research on the instrument exists. Study 1 provides data on the predictive validity of the DPST for total and component scores of the Comprehensive Test of Basic Skills (CTBS). It was hypothesized that the DPST total and partial scores would significantly correlate with the CTBS Reading Total as would a subset of the DPST subtest scores with the CTBS Reading Total score. Subjects were 107 children with Fall, 1981 DPST scores from the Center for Children with Special Learning Needs plus Spring, 1983 CTBS scores from Hillsborough County Public Schools. Although results indicated some significant correlations, the size of the correlations suggested that they have little predictive value. It is recommended that the DPST be used in conjunction with some other measure. A second study of the predictive validity of the DPST investigated the relationship between preschool performance, as measured by the DPST, and kindergarten success, as measured by the Hillsborough Early Rating Scale (HERS); the relationship betwen the CTBS and the HERS also was explored. Subjects were 101 kindergarten children. Results indicated that the DPST had a limited predictive relationship with the HERS and that the CTBS had only a minimal predictive relationship with the HERS. Results suggest that the use of the DPST as a predictor of later school success is questionable. (RH)
