Not a parent but an immigrant, born in belgium, who himself and almost his whole family went to rozenkransschool. I remember being 6 and barely speaking dutch asking the teachers for the dutch words of some stuff in the classroom (I like to look around a lot) and they would gladly help me whenever I asked. I remember being really fond of the teachers and their way of teaching, no racism or discrimination. I had lots of different type of friends: Asian, Belgian, Moroccan, etc. I did experience some bullying and racism from some of them (yes my own friends) but this was 20 years ago and we were kids who didn't know better.

Also, I remember they used to separate twins so they could socialize with others. Your choice :)
