I think this school thing is bollocks - I'm with Scotty. I note in the paper today (SMH) they list a few schools and various categories on the front page. 2 of the prominent primary schools are in Paddington and Woollahra. Now call me a cynic, but I suspect there is a higher chance that one or both parents of many of these kids are professionals with tertiary education, as compared to a public primary school west of Penrith for example. I also know many kids in this neck of the woods are being tutored from early ages outside of school (and yes, from age 5 onwards, believe me) because, strangely enough, their parents have more coin and can afford it. Not to mention the handy donations they might make. Hence the "raw material" is quite different from place to place. Simple things like this skew the data, and I think the whole thrust of Julia Gillard's statement the other day about parents "having a go" at deficient teachers is a very dangerous premise.
On a side note, I watched that 7 pm report the other day on Ch 10, and had to change channels - hard to watch an entire panel of guests all trying to fawn all over a politician (Gillard) at the same time with nary a difficult question anywhere to be seen. Kind of like one of naza's "thrashwanks"!! When does the honeymoon end for Rudd and Gillard, and someone from the media actually actually puts the heat on them?
