Precision

The headline is stored to 13 decimals, as published.

Rounded by this site

Never. Tables on screen may show fewer decimals; the files never do.

Changed by this site

Reshaped into one row per country: regional and income-group totals are left out, only the columns listed are kept, each row gets its ISO 3166 code, and some country names are brought to one spelling. No value is recalculated, rescaled or rounded.

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.
