NOTE: Proficiency in numeracy is scaled between 0 and 500 score points. “High school” includes high school diplomas and equivalencies and postsecondary education that did not result in a degree; this category corresponds to the 1997 International Standard Classification of Education (ISCED:97) category "upper secondary" (ISCED:97 levels 3 and 4). “Postsecondary degree” includes associate’s or higher degrees, and corresponds to the ISCED:97 category "tertiary" (levels 5 and 6). Estimates for Chile, Greece, Israel, New Zealand, Slovenia, and Turkey based on 2015 data, and estimates for all other countries based on 2012 data.
