If you take away the fees, does it offer what you want for your child?
Regardless of the payments, does it offer the ethos, the teaching philosophies, the environment etc that you want your child to go to every day?
We live in a weird little microcosm, so for us the choice was more about where it was going to be the 'easiest' for DD to go to school. Her dad is one of the local coppers, and there are lots and lots of people that he comes into contact with, so we are sending DD to a school where lots of cops kids go, so she won't be singled out and out of place IYKWIM? but we are also sending her there for the ethos, the tiny family environment (there are only 10 classes and the school goes all the way to Yr9) that will mean she won't slip through the cracks. If we lived back in country NSW where we had invisaged she would start school the local primary school was the best for her.
Different strokes for different folks but if you strip it all back to the basics it's a bit easier we found.
