Go and do a tour of the potential schools, get a feel for what they are offering and how they function as a school. We did a tour of the 2 local schools around here, even though my older children had already been to one of them. We still decided that we would look at everything with fresh eyes, things change in the years. We ended up sending our DD3 to the other primary school, and couldn't be happier. What they offered was a better fit for our DD, and we felt that she would have the extra assistance available should she need it. The attitude of the principal swayed us enormously too, one was just going through the motions, the other was genuinely interested in every child, and to this day he knows every child by name!

Good luck with your choices!
