A concerning reality in higher education is the persistent disparity in retention and graduation rates between students of color and White students. These persistent outcome differences are commonly referred to as opportunity or achievement gaps. To address these gaps, higher education institutions are enacting targeted approaches to mitigate or eliminate opportunity gaps. Harford Community College (HCC), the institution included in this study, created a race-based student empowerment program in the fall of 2014, known as the My College Success Network (MCSN) to meet the College's strategic plan goal of eradicating achievement gaps due to race, income, gender, and ethnicity. To date, the effectiveness of the MCSN program in meeting the original goal of eradicating achievement gaps has not been determined. This study evaluates whether MCSN predicts improved retention and graduation rates for Black/African American students, the population of students at the institution where the largest opportunity gaps are observed. Retention and graduation were tracked among unique student cohorts over time which eliminated the availability of a true control group when analyzing the impact of the program. Therefore, Comparative Interrupted Time Series (CITS) was used to compare the before-and-after changes in the outcomes for treatment and control groups to estimate the overall impact of the program. The study compared new Black/African American and White students from cohorts entering HCC between 2009 to 2018. Findings showed Black/African American participants in the MCSN academic coaching program were retained from fall-to-fall and graduated in three years at higher rates than Black/African American non-academic coaching participants. The graduation rate gap between Black/African American and White students decreased after MCSN program implementation in 2014.
