KIPP is the equivalent of educational shock and awe. No question it breaks the kids out of the mindset and educational culture that they knew. That’s an unqualified asset to the system. But once they’ve broken out, what replaces it? Where do they go from there?
Like shock and awe, the initial result can be spectacular. But once the flash and bang have faded, do the kids really have the skills to take control of their lives and create the best possible lives for themselves? I’m not sure that a test-prep, firm discpline, drill-heavy regime is really the best way to go about do that.
And what happens to the students who drop out, or who are driven out of KIPP schools? Given their sky high attrition rate this is a crucial question.

Most, if not all, of them eventually die.
Good work in making this connection. It came in handy for my post on the current financial crisis.
