As for how they handle checking the files, I'm not sure. This is a fairly small school - k and 1st only, about 200 kids in each grade. The asst. principal is the main discipline guy, so I feel fairly sure nobody will be paddling my child.
Honestly, I know there has been a lot of outrage here, and I certainly agree. But, as you said, in this part of the country, this is the norm. We, as non-spankers, are definitely in the minority. I think a lot of it is because of the religious "spare the rod and spoil the child" type thinking. This is the middle of the "Bible Belt" and the basic idea that a good whipping is the answer to most discipline issues still prevails here.
If I had more time and energy, I'd be up for trying to get the law changed, or at least the local school board policy. However, the question of out-lawing corporal punishment in schools has been before the legislature several times and has been defeated each time. Honestly, I don't know that I'm up for that kind of fight right now. I'm just happy to know that my child won't be on the receiving end of the paddle.
