The Programme for International Student Assessment (PISA) is an international survey of education systems (e.g., countries) to assess the relative knowledge and skills of 15-year old students. In 2015, PISA surveyed over half a million students in 72 countries and economies. Students were assessed in science, mathematics, reading, collaborative problem solving and financial literacy in a two-hour test.
Based on the problem-solving questions in PISA, the US performs slightly above the OECD average, and Canada comfortably above average. This is interesting, to a degree, since educators and industrialists point to the US capacity for innovation as a lead in global competition. As far as problem sovling quotients being part of innovation, this does not necessary appear to be the case.
