Rousseau said she is trying to close the gap between her black and white students through outreach programs and intensive tutoring, but admitted the problem is bigger than any school can solve.
"You've got kids never had a book read to them," she said, "and they come home from school and their parents are working because they have to put food on the table."
Asked if she will see a time when the AP classes at Central represent the racial mix of the school, Rousseau said, "I think we have a whole lot of work to do in our society before that ever happens."
But Luster, who is struggling to take advantage of the opportunities at Central, is more optimistic.
"Fifty years may sound like a long time, but it's not," she said. "We have such a long way to go, but we have changed so much already."
