The movement toward collaborative models of preservice early childhood preparation, those that attempt to “blend” preparation for both early childhood education (ECE) and early intervention/early childhood special education (EI/ECSE), is entering its fourth decade. This position paper presents a historical analysis of the blended movement through a conceptual framework based on a social foundations perspective that highlights how sociopolitical and foundational influences have affected blended preparation over time. Although blended models were first explored as a means to reconceptualize early childhood preservice preparation for inclusion, the recommendations shared in this article center on the need to reconceptualize blended preparation itself. A call to action is proposed for the development of a robust research agenda and the strategic coordination of advocacy to ensure current and future blended preparation meets the needs of the increasingly diverse contexts, roles, and responsibilities of ECE and EI/ECSE practitioners.
