No child left behind

Do those words sound to something familiar to you? Probably you thought of "Leave no man behind", the motto of the United States Army Rangers. Any relation to it? Maybe, if you consider the military has access to teens data thanks to this Act.
This is a controversial Act from 2001. I found this article about it. Certainly, being able of using your mother tongue is not only important, but absolutely necessary to succeed in the other subjects. No child left behing? How good are we doing it? And here, I am not asking about the U. S. How good are our kids doing? Not about grades, but about knowledge. I am pretty disappointed.
If you have a whole life to read, here you'll find the complete Act. But I assume that's too much reading for someone like me, so I''ll also point at the Wikipedia article about the Act.
