I found a great protest website from Students Against Testing. The site features lots of neat things in PDF format such as bumper stickers, flyers and famous quotes about education. My favorite quote comes from none other than Albert Einstein who said, "Not everything that counts can be counted and not everything that can be counted counts." This site even sells "No more tests" T-shirts.
This should be mailed to every Texas state legislature who wants to expand testing in Texas and to Dubya.
