Educators Can’t Justify Their PISA Da Pie December 5, 2019

A number of commenters around the ‘Tubes have noted that the Organisation for Economic Co-operation and Development (OECD)’s recent Programme for International Student Assessment (PISA) report showed no progress for US students in reading or math. They fault Common Core for providing no educational benefit.

This is true, but I think they missed a key point.

Check this out (from p. 20 in the report):

PISA results show that there is a positive relationship between investment in education and average performance – up to a threshold of USD 50,000 in cumulative expenditure per student from age 6 to 15 (Figure 9). However, after that threshold, there is almost no relationship between the amount invested in education and student performance.

…Australia, the United Kingdom and the United States all spend more than
USD 107 000 per student from age 6 to 15, yet scored no better than (and in some cases, below) Canada, Ireland and New Zealand, all of which spend between 10% and 30% less.

Yes, despite the pleas of teachers and school administrators to stop being greedy and spend more on education, we’re already well past the point of positive return on spending. The US spends about $127K educating kids from the years of 6 – 15, almost 50% higher than the OECD average, and 2.5X the $50K limit on positive return.

When progressives look at health care spending and our country’s ranking in life expectancy, they throw a fit over the high costs and lack of results (even though that’s a stupid, stupid argument and abuse of data). But when looking at the much stronger and more valid relationship between money and student performance, their solution is to tax more and spend more.

But that inconsistency is probably just another indicator of the poor efficacy of our educational system.
