If the basic design of school education is the curriculum, textbooks are the most basic and important essential tool for realizing education according to the plan. Therefore, it is important to make the curriculum well, which is the basic blueprint, but for the design to be implemented properly, making the textbook well, which is the basic tool, is just as important. Therefore, editing and designing textbooks requires more than revising the curriculum and taking a strategic approach. Korea has also been striving to develop textbooks through several revisions to the curriculum, but it has been pushed back by the supply-oriented education policy, and has not specialized and specialized textbook publishers along with securing the expertise of textbook editing personnel. In other words, publishers that publish and supply textbooks should set specific subjects and invest heavily to specialize and characterize them. In doing so, there should be a system improvement that allows specialized and specialized publishers' textbooks to gain an upper hand in competition than those of publishers who publish and supply all subjects without characteristics. Expertise is assessed to be professional when, while continuing to do the same work, the focus and investment on the work, the training and utilization of professional personnel are consistently pursued, and the work of publishing more advanced publications can be done. Therefore, securing the expertise of textbook publishers and editorial staff, which play a key role in compiling textbooks, is a very urgent requirement to resolve.
