Thailand has recorded one of the lowest levels of English proficiency in Asia, according to the 2025 EF English Proficiency Index, which shows a continued global stagnation in English skills since 2020.
The index is based on test results from 2.2 million participants across 123 countries, with an average test-taker age of 26. While English remains the most commonly shared language for international communication, the report highlights a worldwide plateau in progress, particularly in speaking and writing skills.
Thailand ranked 116th out of 123 countries, placing it in the “Very Low Proficiency” category and second to last in Asia. The country scored 402 overall, a 13-point drop from last year. Among the four assessed skills, reading, listening, speaking, and writing, reading was the strongest with a score of 416, while writing ranked lowest at 363. Listening scored 385, and speaking, which also held the lowest global average overall, came in at 377 for Thailand.
