My DS1 (3.5years) will be in Kinder next year and obviously then going to prep in 2017.

one of our good friends has a boy that will start prep next year so we have been discussing schools a fair bit. I know its still about 12 months till I need to actually choose a school, but I was wondering if people could give me some insight into how you chose your children's school.

It seems so hard to me to be able to pick what my DS would require in a school at this point. Will he be better suited to a small school (say approx. 350 students) or will he thrive in a big school (600+) students? We have a few schools around both home and work (all within a 15 min drive) that are not doing a catchment enrolment. The local school close to us has about 300 students but is very diverse in students and from what I have read has about 25% of students that don't have English as their first language. I don't mind the diversity culturally speaking for students where my kids go, but I am worried with such a high percentage that will require extra support it will mean my son is left a little to his own devices?

not sure if that makes sense... its just a big decision and id like to make sure I have taken everythin into account and make the best choice!
