Despite evidence supporting its effectiveness, Extensive Reading (ER) is still not widely adopted, particularly in Japanese high schools, where teachers unfamiliar with ER have expressed concerns about cost, limited class time, and its effectiveness. One possible reason for this hesitation is the perceived lack of transfer to performance on university entrance exams. However, the English section of the Japanese Common Test for University Admissions (Kyotsu Test) is designed to assess reading and listening skills as they apply to real-world communication. Fluent comprehension of relatively simple texts is now an integral part of the exam, suggesting that ER could be an effective preparation method. This poster presentation examines the test’s question formats and reading passage characteristics. Additionally, it explores how the vocabulary and syntax profiles of several popular ER book series align with the Kyotsu Test reading passages by compiling and analyzing a corpus of test passages and graded readers.
