This study aims to analyze the performance of ‘Happy Seed Schools, which are innovative schools in Chungcheongbuk-do. The subjects are 40 kindergartens and elementary, middle, and high schools, which were designated as Happy Seed Schools from 2016 to 2019 by the Chungcheongbuk-do Office of Education. Research data included 6 reports of the interim and comprehensive evaluation of Happy Seed School from 2018-2020, as well as documents, interviews, and observations collected for them. A rubric for evaluation was developed to analyze and evaluate the vast amount of collected data, which consists of four signs and indices for the evaluation of Happy Seed Schools. By applying the rubric to evaluate individual schools and synthesize the results from them, the study investigated the overall performance of Chungbuk Innovation Schools. The result leads to the following observations. First, democratic school managements were achieved and the democratic communication culture was established in Happy Seed Schools. Second, the growth of students was facilitated in those schools through supporting their potential developments with various methods. Third, various endeavors were tested to integrate local communities and connect with the life of students within the curriculum of Happy Seed Schools. Lastly, Happy Seed Schools are experimenting with various types of teaching and learning, including student-centered participatory approaches. The results can provide implications for the operation of innovative and future schools in Chungcheongbuk-do and beyond.
