Hello
There are no league tables but the websites for most schools are quite comprehensive so you can trawl
Through those. There are tests cslled Naplan.
Most schools will put their weekly newsletter on their website which is a far more informative way of finding out what is actually going on.
In my humble opinion schools are vastly different from each other. I'm a supply teacher in the eastern suburbs. My own dds are in prep and grade three. Some schools are all shiny and full of iPads and performing arts centers. Some have a set of unifix cubes.
Some schools have a thousand pupils. Some have 90. There are different pros and cons of both.
There is definitely flexibility with starting times. Mostly in Victoria, children are 5 when they start school. However some are 4 and some are 6. I was most impressed with this when I got here until I realised that 5 and an 8 year old can be in the same class. A lot of schools teach two year groups together. So year 1&2 together, 3&4 together.
I find special needs to not be as well catered for as in the uk but obviously that depends on the school.
In my dds prep class there is no other adult. I don't know how her teacher does it!
Schools have 'voluntary contributions' but they are not that voluntary. Ours is $300ish per child a year. You have to pay for all extras like trips, swimming, or you don't go.
I have just been to the school uniform shop this morning to buy a wide brimmed hat for next term. Our school uniform provider is called 'Primary School Wear' and it has a website.
