So What?
1) The Organisation for Economic Co-operation and Development (OECD) tested 15 year-olds in several countries in math,
science, and reading as part of the Programme for International Student Assessment (PISA). This chart sums the average
scale score of the three tests.
2) 'Multiple of Gross Domestic Product Per Capita Spent per Student Between Age 6 and 15 Years (US$ Equivalent)' shows
how much of a country's economic output it spends on primary education. It's a good measure of how committed a country is to
education spending.
3) To achieve test scores of about 1475, countries spend anywhere from 1.2 times (Poland) to 2.7 times (Austria) per capita
GDP per student.
4) Italy spends nearly three times its per capita GDP per student between age 6 and 15. However, it achieves test scores only
slightly better than Portugal and Greece, which spend only 1.2 and 1.9 times per capita GDP on education.
5) Finland is able to achieve the highest test scores of the group by spending about 2.1 times per capita GDP per student
between age 6 and 15.
6) This chart tells us nothing about how equivalent the tests are when given in varying languages, nor how consistently the
tests were given in the different locations.
