they were only training him in the 3 R's.
Yes I doubt there is anything I could do to stop my dd from learning the 3 R's, so they are not all that important to me.
The one I am looking at is very focused on real games, they seem to play a lot, they are into deep exploration of subjects, and they do bring in a martial arts instructor for PE, they manage a garden. Some of the other warning signs you mentioned I do think I need to still look out for carefully, but they have many open houses, so I might just keep going to some of these and try to get more of a feel. It is worth noting as well that my dd does love the place so far, but that is just the open houses.
