Trust me hun, if you drive past a school at playtime, it is often very very hard at first glance to see any teachers. Usually there will be only one, maybe two on 'duty' depending on the size of the school and they may simply have been in a different area that you couldn't see as you drove past. I don't think you should start changing your thoughts about the school based on this one drive by. If you want, make an appointment to tour the school and ask these things. They will be more than welcome to show you around and give you some information even though it is a while till your little one starts school. Perhaps even look up the school on the net - not the myschool website LOL, but each school will have their own website.
