The elective subject for high school career education, ‘Introduction to Intellectual Property’, has begun to be introduced in 2018 in accordance with the revised 2015 national curriculum. However, there is a lack of systematic teacher education courses or teacher training programs for the subject, which were established without the fundamental study of intellectual property education. Therefore, the purpose of this study is to develop a competency model by identifying the competencies of teachers in charge of the subject, Introduction to Intellectual Property . To accomplish the goal, the teacher competency model was developed through analysis of a variety of teachers competency models, analysis of teaching & learning data collected through the operation of 9 research and cooperation schools in 2017, and 22 leading schools in 2018, observation of teachers participation in teacher training programs, qualitative analysis of high-performing teachers’ focus group interviews, and Delphi survey. Finally, the teacher competency model has been developed with a total of four competency groups, 18 competencies and 52 competency indicators. The Subject Matter Expert’s Competency Group consists of 5 competencies and 20 indicators for teachers content specialties of Intellectual Property, and the Instructional Competency Group has 5 competencies and 15 indicators for teachers instructional design and development. The Career Education Competency Group is developed with 4 competencies and 10 indicators for teachers intellectual property based career guidance capabilities, and the Self-development Competency Group is composed of 4 self-development competencies and 7 indicators for teachers self-discipline in the field of intellectual property education.
