I'm afraid that I can't help you personally with the question about schools, but this may be of some help.. http://www.schule-baden.ch/index.php?id=23
We lived near the Kantonsspital in Dattwil for some years and liked the area very much.
It is relatively quiet, handy for buses into Baden, close to woodland and farmland.
There is a local Spar and some other small shops, a hairdresser, chemist etc. For bigger shopping you would need to go into Baden.
