each for America: Elite corps or costing older teachers jobs?

Greg Toppo:

In 2007, fresh out of the University of Massachusetts-Amherst, Chris Turk snagged a coveted spot with the elite Teach For America program, landing here at Cherry Hill Elementary/Middle School in a blue-collar neighborhood at the city’s southern tip. For the past two years, he has taught middle-school social studies.
One recent afternoon, during a five-week “life skills” summer-school course, Turk tells his five students that their final project, a movie about what they’ve learned, has a blockbuster budget: $70.
“We can go big here,” he says. “We can go grand.”
He might as well be talking about the high-profile program that brought him here.
Despite a lingering recession, state budget crises and widespread teacher hiring slowdowns, Teach For America (TFA) has grown steadily, delighting supporters and giving critics a bad case of heartburn as it expands to new cities and builds a formidable alumni base of young people willing to teach for two years in some of the USA’s toughest public schools.
