Attainment data are now available for 147 countries, 9 more than in the previous release. The data are available in the form of 2 indicators: the highest completed level of education and the minimum completed level of education.

The new educational attainment data follow the levels of education defined in the International Standard Classification of Education (ISCED) 2011. Compared to ISCED 1997, ISCED 2011 makes it possible to present more disaggregated data for persons who have completed tertiary education.

In addition, this is the first UIS release to present time series with attainment data. Data on the highest and minimum completed levels of education are available for the period of 1995 to 2015, allowing analysis of national trends in attainment over time.

The UIS is also releasing an expanded dataset with estimates of mean years of schooling. This indicator measures the average number of years of education completed by a country’s adult population (25 years and older), excluding years spent repeating grades. Mean years of schooling are available for 149 countries, covering the period 1970 to 2014.
