People who took the test in Spanish scored lower than people from Mexico who took it in another language — 101.5 vs 103.7 (1,227 vs 74 people). That is most likely a translation or localization effect, not a claim about anyone's ability — see the method page for the full country-by-country breakdown.
100 is the average score of everyone who has taken the test since 2026-07-15, and 15 points is one standard deviation. People choose to take the test online, so this shows how Mexico's test-takers scored — it is not an official national measurement.
