In this article, we explore the heart of the debate on the nature of the school-family-community partnership and its underlying rationales. We challenge the underpinnings and uses of the ecosystem which is considered at the root of collaborative practices and parental engagement. By inserting the ecosystem into a metatheory, we place collaborative practices along a continuum that reflects the nature and the degree of interactions between those engaged. Our standpoint looks at this partnership in relation to an ecosystemic perspective that is based on contextual and sociocultural perspective. To illustrate how such an ecosystemic logic can be applied to collaborative practices and parental engagement, we refer to the program Famille, école, communauté, réussir ensemble (FECRE), which was implemented in the province of Quebec between 2002 and 2009.
