Any public school teacher can give you at least 15 reasons that standardized testing is a pain in the butt. Here's one to add to the list.
During my break, I just danced down to the office to grab my attendance. A sixth grade student that I had for fourth grade was sitting at a table. Concerned that he may be in trouble (and because I can never mind my own business) I asked him if everything was okay.
He had a doctor appointment that morning. His class is completing a standardized test and because he was late, he cannot enter the classroom. This student is a favorite of mine, and I couldn't leave him sitting in the office for two hours. He's now sitting at my computers working on a math program.
As we walked down the hallway, another late student came in. Her class is also testing. Guess where she is spending her time? Wasted morning.
