Thank fuck, no. Some of the k8 schools in the district do, but my recollection from the substitute days was that it was generally sort of haphazard. Here at the high school, we don't do it at all in the day-to-day. I don't go to enough sports events to know if they do it there. (I know we sing the anthem at graduation, I don't remember if we did the pledge as well)
