This study is based on Self-Determination Theory (SDT) and explores the relationship between Chinese undergraduates' Intrinsic motivation-knowledge, Intrinsic motivation-accomplishment and IELTS speaking scores. In recent years, although there has been an increase in research on language learning motivation and test scores, there is no research on Chinese undergraduates' intrinsic motivation and IELTS speaking scores. Empirical research on how intrinsic motivation affects IELTS speaking performance in undergraduate groups is still scarce, so this study fills this theoretical gap. The study conducted a questionnaire survey on 100 undergraduates in Anhui Province. Data analysis showed that intrinsic motivation-knowledge and motivation-accomplishment significantly and positively correlated with IELTS speaking scores. This study is about language teaching design, motivation stimulation, and examination. This article provides a new theoretical basis and has important practical significance for improving the IELTS speaking scores of Chinese students.
