It is well established that adverse childhood experiences (ACEs) are linked to health and emotional outcomes. But less is known about the relationship between ACEs and educational attainment—a potentially important feature of educational stratification in America. Using the National Longitudinal Study of Adolescent to Adult Health (Add Health), a nationally representative youth study of 7-12th grade students in the 1994-95 school year, I investigate whether ACEs is linked to post-secondary attainment and examine the role of health and socio-emotional factors as mediators. Results confirm that there is a graded relationship between ACEs and timely bachelor's degree attainment. I find that an additional ACE decreases the odds of timely bachelor's degree attainment by about 17%, even after accounting for other related factors.
