To effectively collaborate with student assistants providing learning support in academic libraries, it is necessary to determine required proficiencies for student assistants based on their role. This paper examines the Kyushu University Library as a case example of collaboration with students and focuses on the proficiencies of student assistants for learning support. We clarify basic and practical proficiencies, which are classified according to activity areas and approaches. In addition, in regard to each proficiency, we indicate whether librarians should provide training opportunities. The tables of proficiencies we propose in this paper are useful in the recruitment and training of student assistants and can contribute to the development of proficiencies among academic librarians tasked with supervising student assistants.
