The purpose of this study was to determine if there is a relationship between college retention and completion and the number of college credit hours students earn before graduating high school. The number of credit hours a student earned was analyzed along with selected demographic characteristics and academic performance indicators to determine if any one of the variables was more of a predictor of retention and completion of college than the others. The data for the study (12,834 records) were obtained from the Student Information System from five Tennessee Board of Regents Universities. An initial analysis of the data incorporated simple descriptive statistics in the form of frequency tables. Cross tabulation and chi-square were used to compare the gender and ethnicity population of dual/joint-enrolled students and nondual/joint-enrolled students. To determine if dual/joint-enrolled students had greater academic success than nondual/joint-enrolled students, a t-test for independent samples was used to compare high school grade point average, the standardized test score average, and first semester and last semester attended grade point average of the two groups. Chi-square was used to analyze if there was a difference in the retention rate and the time it took to obtain a four-year degree between dual/joint-enrolled students and nondual/joint-enrolled students. A one-way ANOVA was used to determine if the number of college credits earned while in high school had any influence on the time it took to finish a four-year college degree. Multiple Linear Regression was used to see if any of the variables could predict academic performance for a studentÆs first and last semester grading period. Discriminant Analysis was used to determine if any of the variables in the study were predictors of completing a four-year degree. The researcher found that students who participated in dual/joint-enrollment programs had more academic success and a higher retention and graduation rate than those students who did not participate in such programs. The study also revealed that dual credit hours had a significant influence on time to completing a degree.

The purpose of this quantitative research study was to explore dual enrollment as a college readiness strategy and the effects of dual enrollment programs on persistence and achievement within a post-secondary institution. This study examined documented institutional data of former dual enrollment students and their direct entry peers who were 1st-time college students at a community college in South Mississippi. Community colleges in Mississippi have maintained dual enrollment programs for over a decade, but few empirical-based research studies have been conducted to determine whether or not student achievement and persistence rates differed for students with prior dual enrollment experience. Therefore, more empirically-based research is needed to determine whether research findings are generalizable. Further research will contribute to the body of literature regarding the impact and effectiveness of dual enrollment and how it relates to college persistence. The sample included all students who graduated from local service area high schools in the spring of 2012 and matriculated to the community college in the fall of 2012. The study analyzed measures of achievement and indicators of persistence for all students over 2 academic years. The study used an independent sample t-test to compare whether prior dual enrollment students had different rates of persistence and achievement than direct entry students. A factorial analysis of variance was used to test for significance among independent variables of enrollment type with the dependent variables of persistence and achievement among categorical variables of race to determine if there was a difference in proportion of students in dual enrollment versus direct entry. Persistence is defined as the continuous full-time enrollment from the first year to the second year. Achievement was measured using ACT scores and grade point average (GPA). Findings revealed that no significant difference existed in measures of persistence between students with prior dual credit and direct entry students. Significant differences existed in measures of achievement by students with prior dual credit and by direct entry students in two areas: Act scores and cumulative GPA. Other findings indicated differences did not exist for persistence by enrollment type and race or for achievement by enrollment type and race.
