DD1 is in Year 5. Here in WA primary school is finished at the end of Year 6 and you subsequently start high school in Year 7.

To get into a private high school you traditionally have your interview process term 1 Year 5 - so now. Public high school I am not sure about.

DD has been to one interview yesterday and has another one in a fortnights time. The whole choosing a high school business is doing my head in and I am so confused so am after some advice.

Option 1 - Catholic girls only high school. Great facilities. Love the school and the support and education it offers. One of the top schools in Perth re tertiary entrance scores. None of her friends will be attending.

Option 2 - Catholic co-ed high school. Again great facilities. A larger school with good results and support/education. A number of her friends will be attending.

Option 1 is more expensive pa by around $2k but that isn't too much of a factor. DD is a very sociable child so should make friends easily but would it be better to have the transition factor with some friends from her primary school?

I actually love Option 1 and that is my first preference if DD was my only child BUT the big thing that keeps playing in my head is would it be nice for the kids to go to school together?

My sister is 13 years younger then me so we never attended school together. DH says it actually doesn't matter re siblings and that once at school you pretty much ignore each other all day. So in his eyes he thinks I am silly to think about it.

Logistically it would be harder at the single sex schools and it would be easier at the co-ed. For at least 1 year we would have all 3 together.

Thoughts??
