Second: Even if this school has good results, it seems unlikely that it will scale well, because it's relying on more money (from outside donors, etc.). You can't throw more money at a problem, then declare you've come up with a general solution.
From Larry Summers talking with Tyler Cowen:
COWEN: And this is K–12.
SUMMERS: Yeah. That’s likely to be the most effective thing that you can do, but that you need to be very careful not to succeed by cannibalization. Many, too many, philanthropists interested in education decide they’re going to set up a charter school. Only their charter school is only going to admit highly motivated kids with highly motivated parents.
Their charter school’s going to pay 20 percent more than the regular schools and cherry-pick the best teachers out of the regular schools. Then they’re going to be really thrilled about how they have better achievement than the regular public schools when it’s clear from the nature of their model, selecting the kids and cherry-picking the teachers, that it is supremely nonreplicable.
I would say impose a replicability constraint on yourself and innovate in the area of education. My general view has been that a lot of the way successful innovation happens is alongside big systems.
