This study aims to analyze the flow of school curriculum development in Korea and present future tasks. To this end, a qualitative meta-analysis of school curriculum development cases was performed according to Tyler's rationale. Tyler's rationale consists of 'establishment of educational purpose', 'selection of learning experiences', 'organization of learning experiences', and 'evaluation'. Based on this rationale, a qualitative meta-analysis was conducted on cases of 14 schools presented in 10 studies on school curriculum development. As a result of the analysis, the teachers of the school studied established educational goals mainly with 'student needs' and 'an analysis of modern society' in mind, and the educational goals established in this way were stated in the manner of 'desired human image' and 'competencies to be nurtured'. In addition, 'integrated curriculum topics' were selected to provide 'meaningful learning experiences for students'. In addition, efforts have been made to expand process-based evaluation to restore the essence of evaluation. However, it is not receiving much help from the "curricular expert's opinion" at the curriculum purpose setting stage, limited student participation at the "learning experience selection" stage, insufficient awareness of the "learning experience organization" method, and not using the evaluation results to improve the school curriculum. In the future, the development of the school curriculum based on the autonomous expertise of teachers should be more active. To this end, a deliberative process that raises questions necessary for the school curriculum by itself and finds answers to them should be activated.
