This paper elaborates on the Multiple Streams Framework (MSF) as a methodology for examining agenda setting, policy change, and policy making networks. The MSF suggests that policy making is not an outcome of rational decision-making and policy cycle linearity; rather, policy formation is characterized by ambiguity and constituted by the interplay between five key elements: three independent streams – problems, policies, and politics – and the influence of policy windows and policy entrepreneurs (Herweg, Zahariadis & Zohlnhöfer 2018; Kingdon 2014; Koliba et al.2019; Zahariadis 2016).The present paper focuses on how agenda setting and policy change could be understood as the result of cross-sectoral coalitions of government bodies, stakeholders, and interest groups that, at critical points in time, find ways to couple the three streams together to promote their pet proposals on the agenda. Since those who play a crucial role in policymaking are subject to change, including the composition of decision-making bodies, such fluid participation affects turnover. Moreover, education reforms and curriculum change are typically the result of “‘spillovers’ from one policy sector to another” (Kingdon 2014, 175). This implies a focus on the relationship between inter-governmental and cross-sectoral collaborations, including fields involving public education policy and the cultural sector. Reference is made to the conceptual design of a newly initiated study of the legitimization of specialist schools. However, the presentation’s aim is to promote a discussion on whether, and how, the MSF may be useful for analyzing education policymaking.
