My husband and i also like CAIS. I also talked with someone know about the teachers and students in church, the teachers are good (with heart in education and treat students good) and the students are behaved and not look like some "international school students".
Why you can approach CAIS parents ? in what occasion you can contact them ?
There was an open night held on few weeks ago at Former Saint Too College. Actually the open night was for parents (K~G2 in this academic year). I and my husband talked to few parents.
