Purpose of this paper is mainly to discuss relevant legal issues derived from preschool educators being dismissed and determined incompetent for preschool educators in a written notice due to “improper discipline”. This study was conducted through researches on laws and regulations, systems and case studies, as well as case and literature review. In this paper, administrative litigation cases and current practical treatment modes were reviewed from the interpretation and applicability of laws and regulations on improper discipline of kindergarten educators. It was found in this study that defects of current practices included unclear division of power. Competent authority might also exercise inactive discretion. In addition, the Ministry of Education failed to inform the related person when notifying the kindergarten of dismissing the preschool educator in writing. It was an improper act in terms of organizational and procedural guarantee. In this paper, it is believed that from the beginning of execution of laws, jurisdiction of relevant authorities shall be expressly defined. Competent authority shall exercise its discretion properly. In addition, guarantees critical to constitutional right to work should be provided with complete organization and procedures to meet relevant laws and regulations.
