Abstract
This study investigates the impact of motivational factors on IELTS reading test performance among Chinese learners. It aims to assess the level of motivation, examine its correlation with IELTS reading achievement, and identify the most influential predictor among intrinsic and extrinsic motivations. Using a quantitative research design and a sample of 242 students from 12 IELTS training institutions in southwest China, data were collected via the Motivation in English Reading Questionnaire (MERQ) and Cambridge Practice Tests for IELTS. Results indicate a significant positive correlation between motivation and IELTS reading scores. Multiple regression analysis revealed that intrinsic motivation (efficacy and engagement) is the strongest predictor of reading achievement. These findings highlight the importance of motivation in standardized English proficiency assessments.
