Research on parental involvement has traditionally focused on social class differences in parenting behavior throughout early childhood and K-12 schooling. Yet there is mounting evidence that similar class divides persist as children exit high school and progress through young adulthood. This review examines parents' roles in young adults' lives, focusing on class differences in non-financial forms of involvement. These processes are often hidden from public view and have received less attention in prior reviews. Beginning with the transition out of high school, I discuss current research on parents' roles in relation to five traditional young adult milestones: finishing school, finding a job, leaving the family home, getting married, and becoming a parent (Furstenberg, 2010). The findings underscore that understanding the transition to adulthood requires understanding young adults' relationships with parents.
