I work at a company that is involved in providing consulting services to K-12 educational organizations (that is, schools). My officemate gets the pleasure of writing & rewriting our testing coding, which basically handles the testing & test scores of students.  Therefore, it should be no surprise (or, well, at least only moderately surprising) that I found the following site mildly interesting:
http://www.fairtest.org

This is an interesting organization whose purpose is to show the implicit failure of standardized testing.  I have to say, I kinda agree with some of their points…I almost wish I could help them redesign their website…
