From the article:
According to the National School Boards Association, for-profit organizations today run about 12 percent of all charter schools. Nonprofits run 20 percent, and the rest — 68 percent — are so-called “mom and pop” charters, run by parents and local community groups.
Some are doing really well. Others are doing quite poorly. Most charter schools, though, are doing no better than traditional public schools, Kolderie says. He says they’re just not being innovative or radical enough in their approach to teaching and learning.
“The concept of autonomy at the beginning was to be free to try new models, including different concepts of what was meant by achievement, performance and success,” he says.
Going forward, Kolderie says, the charter school movement will be grappling with whether charters even make sense if they’re doing what everybody else is doing.
