Kerry: thanks for your comment, and best of luck with the teachers at your school. Hopefully they will fall in line with the administration.
ColinsMum: Hm! It's not too far. I'll have to at least look into residency requirements.
Dbat: Fantastic, thanks! I'll check it out.
geofizz: Good to remember. We looked at one school (which is promising but has other issues) in which the principal said to us, in passing, "Of course, sometimes kids from Kindergarten walk up to 2nd grade for math." This was without our asking.
