Q&A with Tim King

At Urban Prep Charter Academy for Young Men, students dress in suit jackets and ties, wear close-cropped military haircuts, attend classes from 8 a.m. till 4:30 p.m. and then, participate in mandatory after-school programs. Tim King, the former head of Hales Franciscan High, wants to replicate the charter elsewhere in Chicago and nationwide. King talked to writer David Smart about the philosophy behind Urban Prep and how single-sex education can help young black men succeed.
