As a result of the Fourth Industrial Revolution, new digital technologies, vastly different from those of the past, have emerged in society, with artificial intelligence (AI) receiving the greatest attention. Consequently, research is actively being conducted in art education to determine appropriate approaches for utilizing AI. This study focuses on the role of teachers as central figures in art education, positing that teachers' AI competencies are essential for the effective integration of AI into art education. The purpose of this study is to identify the AI competencies required for art educators, based on this perspective. To achieve this, we focused on UNESCO's (2024) 'AI Competency Framework for Teachers,' which outlines AI competencies for educators applicable to school education worldwide. This framework was reinterpreted in relation to the competencies outlined in the 2022 revised art curriculum. As a result, we identified five key AI competencies for teachers in art education: aesthetic AI competency, ethical AI competency, creative AI competency, educational AI competency, and developmental AI competency. It is hoped that this study offers insights into implementing AI in art education in ways that preserve the intrinsic value of the arts.
