03The whole field at once
The spread
79 countries, one dot each, on one scale — further right is a higher value. Half the countries are above 442.09; a quarter are above 483.65, and a quarter below 388.68. The bar in each row marks that continent’s middle country.
04All 79 ever measured
Every country
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.

Over time
Each point is one PISA cycle, 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.

72 countries were measured in both 2018 and 2022. The field changed from 72 to 79 countries, so a place can move for reasons that have nothing to do with the country itself.

About PISA mathematics scores
PISA Mathematics is the mean score 15-year-olds achieve on the OECD’s mathematics scale, which is centred near 500 across OECD countries. Run in seven cycles since 2003, it is the most-quoted international comparison of what school actually teaches.

11Questions
PISA mathematics scores: questions and answers
Which country has the highest PISA mathematics scores?
Singapore, at 574.66, among the 79 countries compared in 2022.
Which country has the lowest PISA mathematics scores?
Cambodia, at 336.40, among the 79 countries compared in 2022.
How many countries does the PISA Mathematics Performance cover?
79 in 2022. The number measured varies from 35 to 79 between editions.
What is the world average PISA mathematics scores?
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 442.09.
Is this OECD’s own ranking?
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.
How often is the PISA Mathematics Performance published?
This site holds 7 editions, describing 2003 to 2022.
Where does the data come from, and can I download it?
From OECD, under OECD Terms and Conditions — Data clause. From the OECD’s published PISA results tables. Sub-national samples the OECD reports separately — Baku and 18 of Ukraine’s 27 regions — are excluded because they cannot be keyed to a country. Every edition is on this site’s Datasets pages as a full table, and downloads as a CSV file with every value unrounded.

How this page reads the numbers
- OECD ranks nobody on this measure. The position is derived by Nations Inquiry by ordering the published values; equal values share a position.
- Which end is better follows the publisher’s own reading of the measure.
- A country is named at an end only when it holds that value alone. Where several share it, the page says how many and names none first.
- Values are stored exactly as published and trimmed only for display. “The middle country” is the median of the countries measured, not a world average.
The file itself, column by column — where it came from, what each column holds, and every edition as a CSV — is on its dataset page.
