Dental hygiene programs are challenging, and admission into the programs are competitive. Dental hygiene program admission committees utilize different mechanisms to select qualified student candidates. Many dental hygiene programs utilize in-person interviews, grade point average (GPA) from pre-requisite classes, and performance in science-based classes as a measure in the student selection admissions process. The purpose of this quantitative survey study was to examine whether a relationship exists between participation in a student success course and student involvement of those who successfully passed the National Board Dental Hygiene Examination on the first attempt using Alexander Astin's Theory of Involvement as the theoretical framework. Not passing the NBDHE has negative consequences for several stakeholders. This study expanded the knowledge base about predictors of success on national dental hygiene board examinations by assessing the relationship between participation in a student success course and student involvement of those who pass on the first attempt of the National Board Dental Hygiene Examination (NBDHE). The independent variable in this study was participation in a student success course, and the dependent variables were levels of student involvement (low, medium, and high). This explanatory correlational survey study design used descriptive statistics to describe participants' characteristics and inferential statistics (chi-square, simple and multinomial logistic regression, and independent samples t-test) to assess the independent and dependent variables. Study results produced by chi-square and multinomial logistic regression analyses indicated no significant relationship between participation in a student success course and levels of student involvement. Data analyzed by independent samples t-test suggested that overall student involvement was higher for those who participated in a student success course than those students who did not take a student success course. Data extracted from the linear regression analysis revealed that participating in a student success course leads to an overall increase in student involvement; thus, completion of a student success course was found to be a positive predictor of overall student involvement and is proven to be related with student success. Dental hygiene program directors may find it beneficial when creating admissions criteria. This study has contributed to the body of literature in relation to dental hygiene students. Limitations and recommendations for professional practices and future research are offered. [The dissertation citations contained here are published with the permission of ProQuest LLC.
