Union Language School Bangkok

Union Language School was established in 1955 by three Protestant Christian mission organisations under the Foundation of the Church of Christ in Thailand, making it one of the longest-running Thai-for-foreigners institutions in the country with approximately 70 years of continuous operation. The campus occupies the seventh floor of the Church of Christ in Thailand Building at 328 Phayathai Road, Ratchathewi, Bangkok 10400, near BTS Sala Daeng. The school’s original work grew out of language preparation for people moving to Thailand. Today it teaches students from a wider range of backgrounds, with a staged curriculum that lets learners see what follows the introductory classes.

Building from tones to Thai texts

Levels 1 to 3 introduce the phonetic script, vowels, consonants, and tonal system while building basic vocabulary and sentence formation, all through spoken Thai, with writing introduced at Level 4. Levels 4 to 6 develop reading and writing, with texts drawn from daily life, cultural beliefs, and social situations. As students move further through the sequence, courses introduce social and cultural topics. This structure gives a learner a reason to revisit familiar words in more demanding contexts. A word first heard in a classroom exchange can appear later in a written passage where pronunciation alone will not explain the meaning.

Advanced students can explore specialised material and preparation for the Thai language competency examination. Before picking a stage, a learner who has lived in Thailand for some time can consider their spoken comprehension and reading experience separately. Someone with strong everyday Thai may still benefit from structured literacy work, while a student who learned mainly from a textbook might want more time responding to ordinary conversation.
