1The Organization for Economic Cooperation and Development (OECD) average refers to the mean of data values for all reporting OECD countries, to which each country reporting data contributes equally. The average includes all current OECD countries for which a given year's data are available, even if they were not members of OECD in that year. Standard errors for the OECD average were estimated by the National Center for Education Statistics (NCES).
2Standard errors were estimated by NCES.
3Although all data for years prior to 2015 were originally calculated using the 1997 version of the International Standard Classification of Education (ISCED), the footnoted countries revised earlier years' data to align with the 2011 version of ISCED, which is the most recent. Most of these countries revised all of their data for years prior to 2015. The exceptions are Denmark (which revised only 2010 data), Mexico (which revised only 2005 and 2010 data), and Spain (which revised only 2010 data).
4All standard errors shown for Canada were calculated by Statistics Canada.
5Data include some persons who completed a sufficient number of certain types of programs, any one of which individually would be classified as a program that only partially completes the high school (or upper secondary) level of education.
NOTE: The International Standard Classification of Education (ISCED) was revised in 2011. Unless otherwise noted, all data for years prior to 2015 were calculated using the previous version, ISCED 1997. ISCED 2011 was used to calculate all data for 2015 and later years. Except where otherwise noted, data in this table refer to degrees classified under ISCED 2011 as completing level 3 (upper secondary education) or to comparable degrees under ISCED 1997. For more information on OECD and NCES estimation methodology used for this table, see the "Online Education Database" section of the entry for OECD in Appendix A: Guide to Sources. Standard errors for 2000 and 2005 have been excluded due to limited data availability. Some data have been revised from previously published figures.
