As many people are aware, the official curriculum guidelines announced in 2017 strongly pushed the concept of curriculum management. The result thereof will be seen in the competency-based curriculum. This is an issue that should be considered not with regard to the ability of each individual teacher, but rather as an issue of school management. However, we do not see many perspectives in actual schools for organically linking the improvements to classes by individual teachers with school management. This thesis explores curriculum management from the perspective of school management, as well as the result of linking the improvements to classes by individual teachers with school management and what is necessary to do that. Furthermore, we use the example of school management through morality education to consider the effects of curriculum management.
