At DD's old public there was actually a list of people begging to be room moms and they were supposedly selected by lottery. Why? Because horrible principal would not allow parents in the school. If you were a room mom you got access, at least occasionally, to see what was happing to your kid 7 hours a day. Of course the "lottery" always seemed to select the parents that were the least likely to ruffle any feathers regardless of what they witnessed. Go figure. 1st grade I entered the lottery but 2nd grade I ran for the hills.
