The Impact of English Tutoring Schools on IELTS Score Improvement in Thailand: A Quantitative Evaluation

Abstract

This paper examines the impact of English tutoring schools on IELTS score improvement in Thailand. Using data from 205 individuals, we employ descriptive statistics, t-tests, and regression models to analyze the effectiveness of tutoring. Results show that the average IELTS score improved from 5.04 to 6.30 after attending tutoring schools, with significant differences observed by gender, age, income, and school. Regression analysis further confirms that tutoring institutions play a significant role in enhancing test performance. The findings highlight the importance of institutional quality and suggest further investigation into additional factors influencing language proficiency. Limitations and future research directions are discussed.
