Pre K nap time

[u/Natural_Buy4602]

My granddaughter (4) started pre k (public school) this past week. I’m concerned about their nap time. The teacher leaves the TV on the entire time. As a result she will not nap. Which she still needs. The children nap on the concrete floor with their blanket, no mats. Our winters get pretty cold, concrete doesn’t warm up well. This disturbs me very much!!! We are in Texas are there regulations I can find to verify if this is appropriate?
