Ausi I am pretty sure I know what school you child is in... my son was there and I found all the teachers to be very unhappy and constantly shouting, and they have no bones about it either... everyday I would go in to pick him up all I could hear was shouting.

If your son is in the primary section, go speak to the nice lady who is head of that section. She can guide you. Also you can go speak to the principal but it is pretty fruitless, she defends the teachers to the death.

Sad... children have a hard enough time to adjusting to a new school and country to be put in such hostile environments. Shame on the teachers.
