Standardized test scores as predictors of success on the dental hygiene national board examination
The purpose of this study was to determine the predictive ability of the American College Test (ACT) and Dental Hygiene Aptitute Test (DHAT) with respect to success on the National Board Dental Hygiene Examination (NBDHE) and which standardized test was a better predictor of success. Research questions included whether the scores of ACT or DHAT of baccalaureate dental hygiene students were predictive of success on the NBDHE. The strength of predictability of ACT verses DHAT was examined. Records of 209 dental hygiene students from the 1975-1984 graduates of Baylor College of Dentistry were used in the retrospective study. The mean, standard deviation, frequencies, and stepwise multiple regression were computed at the .05 significance level. The ACT scores were found to be predictive of success on the NBDHE in 6 of 10 years and the DHAT in 7 out of 10. Neither test made a significant difference in predicting success.
