This document summarizes a study that examined the English pronunciation skills of 147 Thai elementary school teachers. The teachers completed a stress identification test of 50 multisyllabic words to assess their pronunciation competence. They also provided personal information via a questionnaire. The results showed that the teachers struggled with identifying stressed syllables in English words. A statistical analysis found that the teachers' major of study was the factor most significantly impacting their test scores. The findings can help inform professional development for English teachers in Thailand.
