My only hang up with standardized testing is that it isn't accessible but not in the ways people might think. When I was in high school, I saw a good number of people who could not travel to a testing center. The closest testing center to my high school was the next city and with no public transport and a variety of family circumstances they couldn't take the test.

Test also cost money and you could find yourself in the middle class trap where you are too rich to get a waiver but too broke to afford the test.
