The Impact of Dual Enrollment on College Degree Attainment

Dual enrollment in high school is viewed by many as one mechanism for widening college admission and completion of low-income students. However, little evidence demonstrates that these students discretely benefit from dual enrollment and whether these programs narrow attainment gaps vis-à-vis students from middle-class or affluent family backgrounds. Using the National Longitudinal Study of 1988 ( N= 8,800), I find significant benefits in boosting rates of college degree attainment for low-income students while holding weaker effects for peers from more affluent backgrounds. These results remain even with analyses from newer data of college freshman of 2004. I conduct sensitivity analyses and find that these results are robust to relatively large unobserved confounders. However, expanding dual enrollment programs would modestly reduce gaps in degree attainment.
