The thing I have noticed as I watch my friends and family is just how much their personality and mental acuity changes with environmental factors and new interests. I think the vast majority of these tests are laughable because they provide a snapshot without measuring any derivatives (not that you could easily). It's like trying to play the stock market by only looking at current prices. I can see how you might want to do that to pick out kids that are probably teachable, but the downside is that everyone else is penalized despite their current level. I know in college there were several times when I wasn't ready to be taught something, but a year or two later I was. How could we do it better? The only option I can think of that would solve many problems adequately would be to fund all the students so they can seek out a teacher that is right for their level. Too bad that's a pipe dream.
