There are bad tests. However, we have a problem. Most of us would like kids to get as much education as possible given the money we spend. Very few of us are willing to spend money on "education" that doesn't actually educate kids. So, how do you propose we figure out how to spend money on education? If your answer is "spend more", my question is "how do I know what I'm getting for said money?"
