I do have to agree with the R1C...
In Charleston County, we get 3 personal days a year. I have used all of mine. Therefore, if our girls had made it to the title game, I would have had to fudge a sick day in order to be at the game. Then what if my principal grants me the sick day but then wants a doctor's note to verify things? If you're honest, they may say no right from the beginning especially since Friday was a PACT testing day. I know if you teach in a school similar to mine (below average, high poverty, limited subs) there is probably no way you can get a day off to go and volunteer especially during PACT.
I'm not sure how to remedy that problem except to go to a Sat/Sun format or consecutive Saturdays but both of those open up another whole can of worms.
