Abstract Since the announcement of ROC Ministry of Education’s 1995 Senior High School Curriculum Guideline, “Arts and Life” was added as a new subject nationwide. Since then, the Guidelines had been through three revisions each differed from the ’95 original and differed from each other greatly. The current research intended to study and analyze the implicit discourses of the versions. A major focus of the examination was on the shifting power structures among the significant stakeholders involved in the metamorphosis of the texts. It was found that all periods of transition shared similar developmental stages. The first stage was the forming stage in which different ideas were openly addressed. The second stage was the storming and norming stage in which protocols were negotiated and announced. In the final performing stage, all complementary measures and promotional efforts were delivered. In all, the diverse interrelationships within the significant stakeholders during these policy shaping transitions revealed complicated power structures, which remained to be observed in the future.
