In literacy, US adults do okay: the average score across all 24 countries was 273, and the average US adult clocked in at 272, coming in 13th place. In numeracy, things were bleaker: US adults scored 257, significantly below the average of 269, putting them behind Cyprus, Poland, Estonia and the Slovak Republic for an 18th place finish.
In math, Americans with a high school diploma performed about the same as high school dropouts in other countries.
“What makes this so sobering is that this is not a high-level test of math or critical-thinking skills,” Stephen Provasnik, a research scientist at the National Center on Education Statistics, told Quartz.
In digital problem-solving, US adults came dead last, with a score of 274 compared with an average of 283.
