Good teacher performance has a positive impact on the quality of learning, as reflected in students' academic achievements. This study aims to analyze the school's efforts to improve teacher performance, identify the challenges faced, and evaluate professional development programs. Using a qualitative method with a phenomenological approach, the research was conducted through observations, interviews, and document studies at Sompokan Seyegan State Elementary School, Yogyakarta. The data processing involved condensation, presentation, and conclusion drawing, while ensuring data validity through triangulation and confirmability. The findings indicate that optimizing teacher performance requires skill adjustment and training to align with the "Merdeka Belajar" curriculum. The principal encourages teachers to participate in workshops and webinars to enhance their performance. However, challenges arise from limited collaboration with other institutions, low participation in training, and reliance on independent resources such as YouTube videos. Misconceptions about the scope of teachers' duties, along with inadequate facilities and infrastructure, also pose challenges to improving the quality of education.
