Oh dear. Is this stupid simplistic implicit idea really what all this support for RTTT comes down too? The idea that testing + charter schools --> public schools that are as good as private schools?
Because gawd that's stupid. Since (a) as Valerie Steele points out, it's a path directly away from that kind of schooling so long as all this signature testing is involved, and (b) it overlooks the HUGE OBVIOUS difference and obvious path to making them more equal: spend a lot more money per student on virtually everything. Which RTTT is a facile substitute for, if not verily a path towards spending less (firstly on teachers).
This is almost Victorian in its smugness.
