my dd came home saying she moved to another reading group, although when I asked her who is in her group she still says most of the kids who used to be in her group. It seems that the teacher of her group changed, but dd thinks she was moved down a group because of that. Should I speak with the teacher and double check which group she is in or will the teacher see me as a competitive mother?
A child moving 'down' a group doesn't necessarily mean they haven't made good progress. It may mean that other children have excelled their progress and are therefore working at a more able level than your child. I have done this today (maybe you're one of my parents?). I have two children who moved down because they are better being more confident with quieter children than having to compete with those who are more outspoken. Also one of them is an extremely able reader but very slow, which slows down the pace at which the group reads. Another child moved down because although his reading level is at the required stage for Y2, his comprehension levels are below and therefore needs a book that is less challenging on the comprehension side of things. As long as YOUR child is making good progress, I wouldn't worry.
