People who took the test in Thai scored lower than people from Thailand who took it in another language — 99.7 vs 104.2 (3,015 vs 139 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 Thailand's test-takers scored — it is not an official national measurement.
