This paper describes the assessment of the competency of students’ information literacy and information fluency in order to obtain the levels of university student competency in Japan. As the results, a significant difference occurred between pre- and post-tests for all courses. The difference indicates that the students’ skill improved through these courses. In addition, although year-to-year differences occurred, no overall trend was seen. For mixed-year courses, no difference occurred in the school year. The result of the investigation about difficult fields for students to understand revealed that students tend not to understand accurate definitions of technical terms and lack net manners regarding sending email. The results will contribute to the course design of an information fluency course in the future.
