Studies on innovative curriculum institutionalization (ICI) have burgeoned since the 1980s, synchronizing with the developmental background of the institutionalization theory. Both of them were influenced by the rational choice theory, organizational sociology, and historical institutionalism and appeared to focus on different issues. The three models of ICI consist of regulative, normative, and cognitive aspects, and some indicative behaviors are included, such as herd mentality, routine work, and enculturation of normative value. Compared to curriculum implementation, ICI was never highly respected as a field of study, and its accumulated research results are rather limited. Hopefully, future studies in the field of ICI may cooperate with other different domains (such as implementation or dissemination) in order to enrich the scope of research on the process of curriculum innovation.
