I think you are living the dream in some ways. A supportive teacher and a peer for your child!
You are correct though, the experience is very teacher dependent. I would have no problem having some in depth conversations with this teacher and picking her brains about how she says your daughter's educational path within that school. Ask her advice about getting the challenge level right but also start planning now for the next few years. They will come upon you very quickly and this teacher sounds like a great advocate and resource.
