Every nation carries out needs analysis for curriculum revision before developing a national curriculum. Once needs for curriculum revision are analyzed, the results are reflected in the revision. In conducting needs analysis, they define the gap between what it is and what should be is defined, the nature and causes are identified, and priorities for future actions are decided. This study set out to analyze the needs survey taken when developing the Seventh National Social Studies Curriculum and the preliminary research conducted for another revision of the social studies curriculum. It also aimed to identify the current state and problems of needs analysis, suggest directions for improving it, and provide implications for future development of social studies curricula. Needs analysis should be improved as follows in terms of procedure, content, subject, and group method so that needs for social studies can be widely accepted in the revision process and reflected in a revised curriculum: First, it is necessary to review the models of needs analysis in the procedure of needs analysis, set up a common procedure for needs analysis based on the common elements of needs analysis, and make use of it when revising the old social studies curriculum. Second, a broad perspective should be taken of the aspects and directions of social changes and the demands for future society in respect to the content of needs analysis for social studies. Third, a wide variety of individuals should participate in the development of a social studies curriculum including distinguished scholars and practitioners of various fields such as politics, economy, society, culture, and diplomacy, the government, community experts, pedagogists, curriculum experts, and parents. Fourth, the methods of needs analysis should be diversified according to the contents and subject groups and furthermore be regular and long-term to constantly examine social needs. Finally, the results of needs analysis should be presented according to priorities. Those who conduct needs analysis need to determine the priorities of the analysis results based on importance and feasibility, which are the reference to determine priorities, so that the results can serve as useful information for decision making. In a country like Korea where a national curriculum is regarded as holy scripture, partial revisions are preferred to all-out revisions when deciding directions for future education. In addition, it\'s important to have research institutes conduct constant research, required personnel, enough applications in the field, and works of revision before making the final decisions.
