The purpose of this study was to determine students' success by examining the effects of certain demographic variables (gender, race/ethnicity, age, GPA, and course pass rate) on degree completion (certificates and associate degrees) at a suburban community college in the Mid-Atlantic region over a period of seven years (from 2012 to 2018). In addition, one basic factor that influences graduation in college is persistence based on the enrollment of students in school every semester. The independent variables in this study included gender, race/ethnicity, age, GPA, and course pass rate. The dependent variables included certificates and associate degree' completion. Descriptive statistics were used to summarize and classify the community college students' demographic characteristics. A T-test and analysis of variance (ANOVA) were conducted to assess the effects of certain demographic variables (gender, race/ethnicity, age, GPA, and course pass rate) on the completion of certificates and associate degrees. Some of the major findings in this study indicated that female and white community college students had higher associate degree completion than their counterparts. Black community college students had higher certificate and associate degree completion than the other racial groups but not higher than their white counterparts. The data collected, were analyzed and compared to examine issues affecting the graduation rates among community college students. Therefore, the results from this study would contribute to the existing research on students' persistence and degrees' completion. Finally, the other major findings in this study along with the recommendations for professional practices were geared toward future research studies.
