This study explored a conceptual model of competency tasks using the Competency-Based Education (CBE) Scale, grounded in the OECD's competency framework, which includes knowledge, skills, values and attitudes. The survey incorporates six OECD-defined skill types essential for human learning: cognitive, metacognitive, physical, practical, emotional and social skills, building a preliminary model of competency tasks. The study aimed to identify the core elements and construct a conceptual model of competency tasks as perceived by educators. The System of Competency-based Curriculum Design (SCCD) supported educators in creating competency tasks for final assessments in competency-based units or courses. Factor analysis was conducted on data from 317 teachers across various educational levels in Taiwan, all of whom completed five-day SCCD training sessions. Findings demonstrated the scale's adaptability, reliability and validity, revealing four components: Fundamental Abilities, Creative Problem-Solving Abilities, Values and Attitudes. Confirmatory factor analysis further validated this competency task model.
