The Economist (Los Angeles & New Orleans):

OUTSIDE New York, as usual, it is a different story. Most American mayors look longingly at Michael Bloomberg’s accomplishments and wish they were equally mighty. West of the Mississippi, none has succeeded in seizing control of a school system. Nor are they likely to be able to do so: the early 20th century progressive movement, strongest in the West, severely blunted their powers. “We haven’t had reform from the top here,” says Eli Broad, a Los Angeles philanthropist. “So instead we’re seeing change from the bottom up.”
In the vanguard are charter schools like the Academy of Opportunity [Ask Google Live Yahoo] in south-central Los Angeles. Here 13- and 14-year-olds, almost all of them black or Hispanic, firmly shake your hand and outline their plans to go to Yale and Stanford. They work long hours—from 7.30am to 5pm five days a week, plus four hours every other Saturday. The grind pays off. At the end of their first year in the school just 28% of pupils are proficient or advanced in maths, compared to 48% of pupils elsewhere in California. By the time they leave, three years later, they far outperform their peers.
