BETWEEN classes at Fenger High School, on the far South Side of Chicago, hundreds of students churn through the halls. Elizabeth Dozier, the new principal, keeps a watchful eye. “Let’s go, gentlemen!” she shouts. “Let’s go to class!” Ms Dozier wears a two-way radio to deal with problems the minute they arise. One is small: the girls’ toilets have no paper towels. One is bigger: there’s a brawl upstairs. It’s not to be ignored: on September 24th an honour-roll student was beaten to death near Fenger, swept up in senseless violence.
For an idea of the task confronting Arne Duncan, Barack Obama’s education secretary, Fenger is a good place to start. The school lies closer to Indiana’s mills than Chicago’s Magnificent Mile. From 2006 to 2008 fewer than 3% of pupils met Illinois’s meagre standards of achievement. But this year everything is supposed to change. The Chicago school district chose Fenger as a “turnaround”. Old teachers have been sacked and new programmes put in place. Fenger faces formidable odds. But if Mr Duncan has his way, the school’s transformation will be the start of a larger shift.
