I agree... stay with the school you know if you're happy with it.

It's funny because our street is full of kids... who go to different schools: a Catholic school up the street, a Francophone school a bus ride away, our local FI/Montessori school, and so on. Also several former classmates of my kids go to private schools (for various reasons including religion, specialized curriculum and parental accessibility). It kind of seems to be the norm here... that catchment/location means less than suitability.
