The impact of text reading fluency on reading comprehension has been extensively studied. However, a consensus on the direction of their relationship is lacking, which may be compounded by the nature of this relationship that continues to evolve during the course of reading development. This study aimed to examine the relationship between text reading fluency and reading comprehension, focusing on whether the pattern of this relationship varies across different reading development stages. A total of 416 elementary school students in China were selected as participants. Assessments were conducted twice at a 6-month interval for children studying in grades 2, 4, and 6. The cross-lagged panel model was constructed to explore the dynamic relationship between text reading fluency and reading comprehension. Non-verbal intelligence, decoding, vocabulary knowledge, word-reading fluency, and the auto-regressive effects of text reading fluency and reading comprehension were strictly controlled. The results showed that for children in grade 2, the longitudinal effects between text reading fluency and reading comprehension were not significant. In 4th-grade children, text reading fluency in the first semester was found to be a significant positive predictor of reading comprehension in the next semester, whereas for children in grade 6, reading comprehension in the first semester significantly predicted text reading fluency in the next semester. The results suggested that the nature of the relationship between text reading fluency and reading comprehension is dynamic and complex, varying as a function of grade or the reading development stage. •The relationship between text reading fluency and reading comprehension is dynamic.•In grade 2, text reading fluency and reading comprehension may develop in parallel.•In grade 4, text reading fluency promotes the development of reading comprehension.•In grade 6, reading comprehension predicts text reading fluency longitudinally.
