Predictive validity of dental hygiene competency assessment measures on one-shot clinical licensure examinations.

The purpose of this study was to examine the predictive validity of traditional and nontraditional dental hygiene competency assessment measures on one-shot clinical licensure examinations in a baccalaureate dental hygiene program. Traditional assessment data including overall grade point average (GPA), Clinical GPA, National Board Dental Hygiene Examination (NBDHE) scores, and Central Regional Dental Testing Service (CRDTS) scores along with nontraditional assessment data in the form of Portfolio scores were collected from seventy-four students. Factor analysis and subsequent linear regression modeling were used to explore the ability of four variables (Overall GPA, NBDHE, Portfolios, and Clinical GPA) to predict one-shot clinical licensure examination (CRDTS) scores.
