I have lost count of the number of times I've been told that the key to improving the education of the "disadvantaged" is more money. I wonder about that - can more money convince feckless parents to read to their kids before bedtime? Can more money convince useless parents to force their kids to do their homework and do some study every night?
Now that I have more data, I've updated my graphs on school funding vs NAPLAN scores in grades 3 and 5. The R-squared results are low 0.32 to 0.35, so there's stuff all correlation between NAPLAN results in those years and how much money is stuffed into a school.
Notice that the line slopes down though - the less funding a school gets, the better its NAPLAN score tends to be. That shows that schools with low NAPLAN numbers are getting more money - the big question is whether they are putting it to good use. What's the point of giving them more money if all they do is piss it up against the wall? By that, I really mean the parents pissing it up against the wall. A school and its teachers can only do so much. Parents have to do their bit too. A good school will always have a tough time producing results if the parents don't provide any support and direction to their kids.
