This report builds on the 2013 and 2014 Reports on Unmet Need and Student Success at Maryland Public Four-Year Institutions by providing data on six-year graduation rates for the students in the original 2008 entering cohort. For this report, both descriptive analysis and logistic regression were used to understand the relationship between students' unmet need and their graduation outcomes and to examine the impact of net cost of attendance (NCOA) on five- and six-year degree completion. The primary findings suggest that five- and six-year graduation rates are affected by students' unmet need and family income; those from the lowest income families and with the greatest unmet need are the least likely to graduate. Also, increases in NCOA can have a significant negative effect on five- and six-year graduation rates of students from the lowest income families (those with family incomes between $0 and $65,513). Students in the lowest income brackets are the most likely to see graduation rates improve when they receive sufficient financial aid to meet their need. Among students from higher-income families (those with family incomes of $100,742 or more), students with unmet need have similar graduation rates to those without unmet need. A secondary finding is that the grade point average (GPA) that a student earns in the first year in college is a stronger predictor of graduation than NCOA or family income.
