A Comparison of Attrition Rates in Dental Hygiene Programs Using Selective and Nonselective Admissions

The purpose of this study was to determine if there is a difference between attrition rates for dental hygiene programs that use selective admissions and nonselective admissions. Admissions to dental hygiene programs is based on a predetermined class size; therefore, applicants must meet the criteria to be considered for selection. Dental hygiene programs want to retain their enrolled students and maximize their student successes; therefore, it is imperative to validate current admissions practices that help reduce attrition rates. An online survey consisting of forced choice and open-ended questions was sent to the directors of accredited dental hygiene programs in the United States. Surveys were analyzed using descriptive statistics and frequency distributions. Open-ended questions were analyzed using the constant comparative method to identify recurring themes. Ninety-nine surveys were returned for a 30% response rate. There was no statistical difference in attrition rates when selective or nonselective admissions criteria was used in dental hygiene programs (year 2011 p=.435 and year 2012 p=.784). Results of this study also showed baccalaureate degree dental hygiene programs have significantly higher completion rates than associate degree dental hygiene programs (2011 p=.002 and 2012 p=.005). Evidence from this study suggests there is no difference between attrition rates for dental hygiene programs that use selective admissions versus nonselective admissions. Additionally, this study determined that baccalaureate degree dental hygiene programs have less attrition compared to associate degree dental hygiene programs.
