Abstract
In Korea, the School Library Promotion Act stipulates in Article 12, paragraph 2 that school libraries must have a librarian teacher, practical teacher, or librarian as professional staff in school library. Librarian teacher is a person who is qualified as a librarian teacher under Article 21 of Elementary and Secondary Education Act and is in charge of school library operations, while a practical teacher is a person who has studied library science and is qualified as a practical teacher under Article 21 of the Elementary and Secondary Education Act and is in charge of school library operations. Librarian is a person who meets the qualifications under Article 6, paragraph 2 of the Library Act and works in a school library. This paper examines in detail the legal basis of each qualification to find the suggestions for these professionals to revitalize school library.
