Reading interest and Achievement motivation are two important factors that can improve students' language acquisition. Reading interest is intrinsic, while achievement motivation is extrinsic. This study determined the direct impact of reading interest and achievement motivation on improving text reading comprehension in EFL classrooms. Quantitative methods using path analysis methods can achieve this goal. Questionnaire surveys and reading comprehension tests of English texts were used as tools and were assigned to 60 undergraduate English literature and English education students. Multiple linear regression analysis was used to analyze the data. The results showed that that reading interest and achievement motivation have a positive influence on reading comprehension. The learning process applied in formal and non-formal institutions must be adjusted and supported by facilities to foster interest in reading to achieve achievement motivation. In this way, this helps improve EFL reading and writing skills in the 21st century, especially English texts' comprehension
