This study used Birkland's Event-Related Policy Learning Model to analyze policy changes in teacher’s rights protection policy following the demise of a newly employed elementary school teacher. The objective was to find both policy and theoretical implications of the policy alterations that occurred around a focusing event and during the policy learning process. To achieve this, we conducted a literature review focusing on Birkland's key steps and evidences. The study found that the incident involving a newly hired primary school teacher committing suicide in the classroom was considered as a focusing event, directing society's attention towards the protection of teaching rights. As a result, national-level policies have been implemented to protect the rights of teachers, leading to the amendment of Four Laws on Educational Rights and Child Abuse Law. Based on our research, we identified three points of discussion. First, the focusing event highlighted the failures of the existing policy to protect teaching rights, leading to the need for policy change. Second, through the process of policy learning, the goals and direction of the policy changed. Third, new types of teacher organizations have emerged as major participants in the process of policy change. Based on the above discussion, it was found that past policy experiences and accumulated failures were important factors for new policy changes through the 'policy learning field'. Finally, the study suggests further research on policy learning along with policy suggestions for guiding future direction for teacher’s rights protection policies.
