Early childbirth is common among young women ageing out of foster care and may impede their educational progress. However, few studies have explored access to postsecondary education among young mothers who have been in foster care. The present study used data from a large, national sample of young people in foster care (National Youth in Transition Database, NYTD) to examine the link between early childbirth and young women's access to postsecondary education between ages 19 and 21, controlling for an array of covariates. The study sample included 2,207 young women who had completed a high school diploma or GED by age 19 and who participated in three NYTD interviews at ages 17, 19 and 21. Childbirth between ages 19 and 21 was linked to decreased access to postsecondary education. However, no relationship was found between access to postsecondary education and childbirth by age 17 or childbirth between ages 17 and 19. Implications for policy, practice and research are discussed.
