All i can say is that at least the teacher is talking to you about his reading. Ours won't answer any questions at all. She completely ignored my email asking when is the last time his reading had been assessed and why his reading level is what it is. She saw the email but the only thing she will talk about is acceleration for math, and that is because people higher in the district are now involved.
I also don't think it's a huge deal between late second grade and mid-third grade but if you address it again with them, I would focus on the lack of progress being made and tell them that you expected to see at least one year academic gain from your son in reading, just like what the other kids are seeing. Then it makes them look silly for not teaching him (but you are not directly saying that).
