[W]e have politicians deciding that since Kindergartner's are having trouble meeting the developmentally inappropriate standards of CCSS, the problem must be that they aren't "ready" for kindergarten. So we have the spectacle of people seriously suggesting that what four-year-olds need is some rigorous instruction, and of course THAT means that we'll need to give those four-year-olds standardized tests in order to evaluate how well the program is going.
It's like some sort of unholy alliance between people who won't be happy until they're selling eduproduct to every child in this country and people who won't be happy until we've made certain that no child in this country is ever wasting time playing and enjoying life.
The Big Data machine needs more data. Right now we can only plug your child in when she reaches age five. Oh, but if we could only get our hands on those children sooner. Even a year sooner would be an improvement. Pre-K programs will allow more data collection and fatter file for each child.
Don't you want to know what career your four-year-old is best suited for? Don't you want to be certain that your four-year-old is on track for college? The let us add another link to the Big Data Pipeline.
All this in the name of "investing" — pun fully intended — in children's futures. We're witness to the bastardization and monetization of early education.
