At the website of the National Association of Scholars, an anonymous victim of the educationist racket explains much of what you need to know about why Johnny can't read, write, or calculate (without a calculator). Briefly, it's because teacher's training today is totally controlled by mad folk.
His remarks are "based on a public lecture that the author presented to students interested in issues of campus free speech":
"First, you have to understand that educational policy is consumed by the achievement gap, which is the disparity between groups of students on most educational measures...I don't just mean that this is the number one priority. It's the only priority...Nothing else matters. No Child Left Behind was entirely about the achievement gap and measuring schools to see if they'd closed it. Obama's Race to the Top is just another take...again, focusing on testing and this time holding teachers responsible if they can't get low-performing students to improve."
And, second, you have to understand that, in ed-school, there's only one permissible take on "the achievement gap, its cause and solution" - i.e., "the progressive view...which holds that social injustice, institutionalized racism, white prejudice, and other societal ills cause the achievement gap." Express any doubt on that point - even to the rather timid extent of suggesting, along with those horrid right-wing extremists, the Thernstroms, that differing cultural values may play some role here - and the sociopaths who run the place will do everything in their power to destroy you. Fortunately, in the author's case, they didn't quite succeed (though they did frighten him into anonymity).
So what do our progressive educational overlords really want? They "want to fix the achievement gap by moving underachieving students closer to high-achieving students...who will model desirable behavior..." I.e., for these people, unless your child is an underperforming member of one of the officially approved minorities, they really couldn't care less about what's best for him. So far as they're concerned, his only use is to sit next to the previously mentioned under-achievers in class and to "model desirable behavior" for them. And if, instead, it's the bad habits of the underachievers that end up rubbing off on the better students? No problem. There's more than one way to reduce an achievement gap.
