Tarnagulla Primary School excels

The much-hyped www.myschool.edu.au website says the 41 students at Tarnagulla PS are young geniuses.

Is it the teachers? Fresh air? The rusty old tractor to play on? The fact that everyone knows everyone? Who knows?

Even more interesting is poshness measure, ie. the ICSEA. Can this be true? See below:

Bottom quarter: 0%
Middle quarters: 3% and 18%
Top quarter: 79%

The copy/pasted table doesn't show up properly in my browser:
