The Michigan House has signed off on legislation that would let public school districts create all-boy and all-girl schools.
The measure is expected to reach Governor Granholm's desk soon. The Detroit school district wants to open both an all-boys and an all-girls school.
Supporters say single-sex schools would give parents more options for their children and argue some kids can learn more in single-sex learning environments. But opponents say the plan could create "separate but unequal" schools.
Both the American Civil Liberties Union and the National Organization for Women oppose the measure.
Granholm has said that she'd be open to allowing single-sex public schools as long as there's no discrimination.
