The purpose of this study is to explore the possibility of using gaze tracking tests as a way to identify the needs of screening and reading support for children with reading difficulties by classifying into detailed groups and examining the characteristics of gaze tracking by groups. To solve the research question, 70 children with reading difficulties, corresponding to the 3rd to 5th grades in S city, were selected as the objects of this study. Afterwards, the differences between groups were explored through the gaze tracking variables in the process of reading aloud flency test and the characteristics were identified through gaze path analysis in the process of the reading comprehension test. As a result, they were classified as three groups with significant differences according to reading-related variables. The groups were named ‘Fluency Support Required Group’, ‘Functional Reading Support Required Group’, and ‘Vocabulary Support Required Group’. In the reading fluency test, average fixation time, mean regression time, and time until the first fixation were found to be significant predictive indicators. And in the reading comprehension test, the ‘vocabulary support request group’ showed more actively participaing in reading than the ‘functional reading support request group’. Based on these results, educational implications and suggestions for follow-up studies were discussed.
