Yunzer, there's more to the story than whether anyone is teaching to the test. Personally, I resent that some profit driven company that probably isn't even an American company (I'm thinking of Pearson here) can come in and decide what our students should be learning. Then, let's add insult to injury, many teachers are evaluated on how their students did on these tests, if your students did poorly on this test, well, it's going to show up on your paycheck somewhere down the line.
Then, I resent these tests for one more reason. When my son's safety was at risk in a public school (gang violence), he didn't want to go back to a private school, didn't want to go to another public school, he wanted to be home-schooled. I was working more than 40 hours a week, but this was what my son wanted more than anything, so we went for it - grades 7 - 12. When I had to take time out of an insanely busy schedule to take my son somewhere to take standardized tests, I wasn't happy about it. I took responsibility for my son's education when I disenrolled him. Why does the government need to see test results on him? I felt like they were intruding where they didn't need to be.
My son is over 30, and still says disenrolling him and "unschooling" him is one of the best things I ever did for him. Yeah, he did fantastic on their tests, even though I had no clue how to "teach to the test". But, some kids don't do well...and punishing a teacher that really is trying to teach isn't the answer.
