Abstract: The purpose of this study is to review the process of curriculum revision in order to understand what should be included in the newly revised curriculum in Korea where the national curriculum system is in place. Specifically, this study is referring to the contents that need to be documented within the subject curriculum development as the ‘document system’ and it will look into how the process of revising the document system works and its results. The study was conducted by exploring the current issues of the currently implemented subject curriculums and their solutions through a consultative group with experts from March 12th, 2014 for approximately 10 month. As a result, a set of guidelines for subject curriculum development was produced and was reviewed subsequently. This study suggested a plan to implement core ideas along with the document systematization for the document system and the document systematization included individual factors such as subject curriculum’s characteristics, goals, content structure, achievement standards, teaching and learning methods, evaluation and textbook development. Also, in order to reflect the core ideas to the document system, a new content structure table was developed and this table contained guidelines for each factor. The content structure table was composed of ‘subject area’, ‘big idea’, ‘content (generalization)’, ‘content by grade (grade cluster)’ and ‘function’. The achievement standards were developed by combining the ‘content by grade (grade cluster)’ and ‘function’ which in turn reinforced the relation to the content structure table.
