When Lesley Del Rio goes to the library to do her college math homework, she often has a study buddy: her precocious 8-year-old son, Leo.
Del Rio is working on her associate degree; Leo is working on third grade.
And Del Rio is not alone: More than 1 in 5 college students in the U.S. are raising kids. That's more than 4 million undergraduates, and they are disproportionately women and people of color. Of those students, more than half will leave school without getting a degree.
