This study explores the growing conflict between teachers’ professional authority and parents’ rights in Korean schools. Based on the principle that the educational rights of teachers, students, and parents should be mutually respected, the study investigates conflict patterns and possible mediation strategies. Focus group interviews were conducted with 15 teachers and 9 parents from elementary to high school levels. Thematic analysis revealed three core themes: the Realities of Conflict, the Scars of Conflict, and Mediation. Conflicts included demands to alter student records, excessive complaints, and overcautious teaching, which harmed both teacher authority and students’ learning rights. Both teachers and parents expressed feelings of disempowerment, leading to missed educational opportunities for students. Mediation strategies were proposed across three levels: institutional (e.g., policy support), school-organizational (e.g., communication structures), and individual (e.g., mutual understanding). The findings highlight the need for self-reflection on rights and responsibilities and call for rebuilding trust through respectful educational partnerships.
