Results of this international comparative test show worldwide drops over the past 20 years, with accelerations since the pandemic. We should note the scale of the graphic, yet the trend is clear. Poverty, distracting devices, and mental health are offered as potential explanations. East Asian countries and city-states do best in math, and the United States sits a bit below the average. Our close cultural cousins the UK and Canada do notably well, while Australia sits just a hair below the average. It’s interesting that the worst performing students in the US seem to do better than the worst performing students elsewhere. Could this be because of the things we actually do right, like get kids to (a) school regardless of income and give them some calories while they are there?
