U.S. college graduates lack numeracy skills compared to graduates in other countries, concludes the 2013-14 Program for the International Assessment of Adult Competencies.
Overall, U.S. adults met the international average in reading skills and fell below average in math, according to PIAAC. Americans did worse in math than adults in Japan, Finland, Estonia, Cyprus, Canada . . . it’s a long list. 
U.S. high school graduates knew as much math as high school dropouts in other countries, writes Jenny Anderson in Quartz.
In “problem solving in technology-rich environments,” also known as digital literacy, Americans were dead last.
“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, said. PIAAC measures “basic workplace skills.”
