Because between my business and my wife's business, I review probably over a thousand resumes and other communications each year from generally recent high school, college, and professional graduates for positions all across the spectrum of sophistication and subject matters. And maybe two dozen of those (including those who are college or professional graduates) reflect someone who has the basic writing, communication, and other skills expected to be taught at the elementary and high school levels. Call it anecdotal if you want, but I trust my own eyes much more than some arbitrary test scores measuring who knows what.
