I have a friend who has moved to the UK from China with her son. They have been here for nearly two years now and her sons English is pretty good. He has achieved a level 2C.
I suspect that 2C is at end of year 3 and from my limited experience, you should be looking at level 3 at the end of year 3, KS1 SAT. No doubt others will disagree.
She is concerned that the school is not pushing him enough as she expects him to go to the local grammar school. I think she has just realised that the primary school is not very interested in getting kids into the grammar - only in getting the kids to their targets.
She may be right as most schools focus on their SAT results as that is what they are measured on. Also, I am very aware that many chinese place a very high regard on education and are well noted for their high levels of commitment to good schooling. I think it may be a cultural thing that we could learn from in this country.
I can advise her on the process of preparing her son for grammar school exam as I have just done that for my eldest DS, but I am not sure how to advise on bringing his English up to a higher standard.
Show them this website and let them take the lead themselves. English will be the biggest hurdle as Maths and NVR probably translate relatively easily. Try working through the Bond English books, starting at Third level probably and progressing to Fourth papers when possible.
Does the exam process take account of English as a second language?
I have never heard of any 11 plus exam taking account of English as a second language. Maybe they should?
He is in yr 4 now.
Plenty of time to get the English sorted. Good luck and I hope it goes well. Hopefully others can add to my notes and clarify some issues for you.
