Proportion of students at the end of lower secondary education achieving at least a minimum proficiency level in reading, adjusted native parity index (NPIA) by country

The Adjusted Native Parity Index (NPIA) is calculated by dividing the immigrant value for the indicator by the non-immigrant value for the indicator. If the resulting value exceeds 1, the ratio is inverted and subtracted from 2. The adjusted native parity index is symmetrical around 1 and lies in the range 0-2. An...

What the numbers show

Proportion of students at the end of lower secondary education achieving at least a minimum proficiency level in reading, adjusted native parity index (NPIA) is currently reported for 44 countries. The highest value is 1.46 NPIA in Qatar; the lowest is 0.0232 NPIA in Indonesia.

The median across all reporting countries is 0.8082 NPIA, and the mean is 0.8001 NPIA.

The gap between the highest and lowest reporting country is a factor of about 63.

Over the past decade 20 countries rose and 24 fell. The largest increase was in Colombia (up 137.2%), and the largest decrease in Slovakia (down 28.5%).

The Adjusted Native Parity Index (NPIA) is calculated by dividing the immigrant value for the indicator by the non-immigrant value for the indicator. If the resulting value exceeds 1, the ratio is inverted and subtracted from 2. The adjusted native parity index is symmetrical around 1 and lies in the range 0-2. An adjusted NPI equal to 1 indicates parity between immigrants and non-immigrants. In general, a value less than 1 indicates disparity in favor of non-immigrants and a value greater than 1 indicates disparity in favor of immigrants.
