I’m with kenty on this. I wouldn’t be happy if a child of mine was held back because political correctness dictates that non English speaking pupils must be educated in the same class.
They should be taught to read, write and speak English before they join their peers in the classroom.
How else is any child going to learn?
I gave up teacher training for secondary school kids because I didn’t believe in the system of teaching all abilities in one class. Kids need to be streamed depending on their ability as I personally think it is more beneficial to all.
