As someone whose career has revolved around education, I have to say I'm a bit disappointed with these guidelines. The focus is entirely on formal schooling as opposed to education.

The problem is that "widely accepted standards", especially in the US are sub-optimal in terms of educational outcome. Even if Common Core were great (which is not the case), continuing to improve pedagogy and curriculum should be ongoing goals. Similarly, why push people to use a closed system such as Lexile® for rating the difficulty of reading material instead of something open?

On an even more basic level, should edtech offerings be limited to children living in the US at all? I would say no. Most Americans aren't children and most humans aren't Americans.
