I represented our school at a training for a new test we will start administering to our first graders in a few weeks. It was on a school day, so I had to request a sub. Unfortunately, I didn't go through all the steps required and it didn't enter the system until after the fact. I told my principal about it so he took care of it by being the sub.
It was an unusual experience to have your boss teaching your class but he said that it went surprisingly well. WHEW!
