03The whole field at once
79 countries, one dot each, on one scale — further right is a higher value. Half the countries are above 440.35; a quarter are above 481.00, and a quarter below 387.19. The bar in each row marks that continent’s middle country.
04All 79 ever measured
In order, highest value first. “=” marks a position shared with another country. OECD ranks nobody on this measure; the position is derived here by ordering the published values. PISA is an assessment countries opt into, so the 79 economies in 2022 are the ceiling rather than a sample of the world — read this as a comparison among participants, not a world ranking. Some entries are not sovereign states: Hong Kong, Macao, Chinese Taipei, Kosovo and the Palestinian Authority are reported by the OECD and kept here.

Each point is one PISA cycle from 2000, roughly three years apart — the 2021 round slipped to 2022 because of the pandemic. The scale is designed to stay comparable between cycles, so a real gain or loss shows here.

The biggest changes in value between the two newest editions. Places are shown second, because they also move when other countries do.
71 countries were measured in both 2018 and 2022. The field changed from 71 to 79 countries, so a place can move for reasons that have nothing to do with the country itself.

08The measure
PISA Reading is the mean score 15-year-olds achieve on the OECD’s reading scale, centred near 500 across OECD countries. It is the longest PISA series, starting a cycle before mathematics and two before science.
What the number is: Mean reading score.
09Where it fits
Its part in the Country Index, the statistics whose values line up most closely with it across countries, and others on the same subject.

Cambodia, at 328.84, among the 79 countries compared in 2022.
79 in 2022. The number measured varies from 35 to 79 between editions.
This site does not calculate a world average, which would depend on how countries are weighted. In the middle country of the 79 compared in 2022, the figure was 440.35.
No. OECD publishes the values but ranks nobody; the position on this page is derived by Nations Inquiry by ordering the published values, and equal values share a position.

The OECD publishes three separate scales and no composite, so reading, mathematics and science are three indicators here rather than one — averaging them would be our invention wearing the OECD’s name.

8 cycles (2000–2022), covering 35 to 79 economies. The mean score 15-year-olds achieve on the PISA reading scale, which is centred near 500 across OECD countries. Reading is the longest PISA series, running a cycle earlier than mathematics and two earlier than science. ⚠ PISA publishes three separate scales and no composite, so mathematics, reading and science are three indicators here rather than one - averaging them would be our invention presented as the OECD’s finding. ⚠ PISA is an assessment that countries opt into, so the 79 economies in the 2022 cycle are the ceiling rather than a sample of the world, and the early cycles are much thinner. These should be read as a comparison among participants, not as a world ranking. ⚠ Some entries are not sovereign states: Hong Kong, Macao, Chinese Taipei, Kosovo and the Palestinian Authority are reported by the OECD and kept here, while the sub-national samples Baku (Azerbaijan) and Ukrainian regions (18 of 27) are excluded because they cannot be keyed to a country. ⚠ The OECD publishes no rank in these tables, so none is stored; the POSITION shown on the statistics page is derived here by ordering the score, and labelled as ours.
