This article advances that the movement towards "deeper" Caribbean integration has generated a shift from "immature" regionalism to a "mature" form of regionalism. Thus, mature regionalism, a new governance mechanism, in regulating the institutional and legal framework of Caribbean Single Market and Economy is drastically altering national education governance within the Caribbean Community. In focusing on the functional aspects integration, this article suggests that mature regionalism in education is built upon collaborative governance and encompasses multipartner governance arrangement--with the state, private sector, civil society, and the community as well as hybrid public-private and private-social partnerships and co-management regimes. It concludes that the instrumentalisation of mature regionalism in education is giving way to "educational regionalism" defined by the movement towards structured institutional mechanisms, to facilitate the deepening of Caribbean integration.
