I'm yet to figure out why common core is so terrible?
But NCLB basically set up the worst performing schools (compounded by terrible social problems) for failure.
CC is a different brand of crap. It assumes kids in Texas learn the same as in New York, and creates this soulless, almost industrially manufactured youth to provide "services." It doesn't teach kids HOW to think, it teaches them WHAT to think.
If you were trying to come up with something that was the complete opposite of true, you would almost have nailed it with this.
