Despite a substantial increase in government spending per student over ten years (after correcting for inflation), the proportion of students who are proficient in math, reading and science have actually declined over that same period. The Organisation for Economic Co-operation and Development and the Menzies Research Centre have both concluded that increasing school funding above a basic level has little effect on student proficiency. Instead, they both recommend greater autonomy. That is, the states should merely monitor the performance of the schools. Individual principals should have full authority and responsibility for ensuring student proficiency in core areas.
