I also wonder if he is being under placed in the new class? Skipping needs to be supported to work...

My DD skipped into yr 1/2 class 18 months ago, one and a half school years later she's top of the class in some areas, highly placed in all and I wish we'd accepted the double skip that was offered... Sort of... I don't want her double skipped if we can avoid it, but the one year hasn't bought much.
