Ds has been stuck on the same book band for six months. He flew through bands before this.
He can read this level and the next level up very easily with maybe one or two words per book he needs help with (e.g. in a non-fiction book obscure non-decodable words), has good expression and understanding. I think he should be on at least the one above if not two above. I appreciate teachers are experts in all this but ours if very overstretched and hasn't heard ds read for a while. Ds doesn't read much at school but reads tons at home by choice.
How long is it normal for a child to be on a particular level for?
