This follow-up study examined the long-term effects of providing 5 years of high-quality childcare for low-income mothers participating in the Abecedarian study, a randomized trial of early childhood educational intervention for children from low-income families. Participating in the age-21 follow-up were 100 of the original 109 biological mothers; 51 were mothers of treated children and 49 were mothers of control children. Ninety-eight percent of children were African American. Findings indicated that about twice as many teen mothers of treated children as teen mothers of control children attained post-high school education. There were no treatment effects on employment. However, mothers of treated children had a higher average Hollingshead score than mothers of control children. It was concluded that high-quality childcare can have long-lasting benefits for teen mothers. (KB)
