Even though the importance of extensive reading practice is well documented, as are students' changing leisure-time reading habits, knowledge of how much students read at school is still limited. Therefore, this study investigates how many pages of continuous text, nonfiction as well as fiction, students in middle (Grades 4-6) and lower secondary (Grades 7-9) school read during an ordinary school day. Comparing data from two large-scale surveys, in 2007 and 2017, our analyses indicate that the proportion of students who read one full page or more has decreased significantly. More students in middle school compared to lower secondary still read nonfiction, whereas the reading of fiction is now equally low. We conclude that the growing achievement gap among Swedish students on reading literacy tests is mirrored in the widening divide between students who still read extensively at school and those who do not read at all.
