I suggest that you visit the school, look at the environment, hygiene, how the teachers interact with the children & etc. Check out the vibes that the children give out, are they genuinely happy or like military trained. You may want to look out for certain things(eg. Time table, their curriculum, mode of communication(e.g. communication book, email or facebook?) , the set up of the environment if it safe(e.g. any gate at staircase if it is double storey? If the classroom are clutter & messy?)
