How did you get to the 1:8 nursery ratio? My 3 year old is at nursery here and it is brilliant, she loves it and the staff are fantastic and that is 1:6 but there are always additional staff around. A lot more expensive here than UK, Base rate is $430 a week for my daughters nursery but that includes all meals, sunscreen, hats, nappies if applicable which we think is great as we didn't have that in the UK - You get the CCR so not actually that bad in comparison.
Don't read too much into it, i think you can only truly decide once you have been to see a few schools yourself, I don't think you can make a sound judgement on what you read.
