†Not applicable. This level of education was not part of the national education structure; students in the age group normally associated with this education level were reported in other levels.
1 Refers to the mean of the data values for all reporting Organization for Economic Cooperation and Development (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. However, if data were reported for less than 75 percent of the countries, the average for that year is omitted.
2 Junior high school data are included with the senior high school data.
3 Includes only general programs; data on vocational programs are not available.
4 Preprimary data are included with the elementary school data.
5 Excludes independent private institutions.
6 Postsecondary non-higher-education data are included with the senior high school data.
7 Junior high school data are included with the elementary school data.
8 Data from 1999 reported for 2000.
9 Elementary school data are included with the junior high school data.
10 Includes data on occupation-specific education corresponding to that offered at the vocational associate's degree level in the United States.
11 Public institutions only.
12 Senior high school data are included with the junior high school data.
13 Data from 2001 reported for 2000.
14 Excludes general programs; data are for vocational programs only.
NOTE: The pupil/teacher ratio is the number of full-time-equivalent students divided by the number of full-time-equivalent teachers, including teachers for students with disabilities and other special teachers. Data for 2012 and earlier years were calculated using the International Standard Classification of Education (ISCED) 1997. Data for 2013 and later years used the ISCED 2011 classification and may not be comparable to data for earlier years. In this table, elementary school corresponds to ISCED 1997 and ISCED 2011 level 1 (U.S. grades 1 through 6), junior high school corresponds to ISCED 1997 and ISCED 2011 level 2 (U.S. grades 7 through 9), and senior high school corresponds to ISCED 1997 and ISCED 2011 level 3 (U.S. grades 10 through 12).
