This paper presents the methodological approach of the REFORMED project research strand 2 (RS2), specifically, of its qualitative phase. Following a sequential mixed-methods design approach, the qualitative phase aimed to understand the rationales behind different forms of engagement of schools with SAWA policies. The main emphasis is placed on how these policies are interpreted and translated into practice by school actors in different educational and socio-material realities. The main aim of this note is threefold. First, it describes the research objectives and presents an overview of the research design. Second, it presents the data-collection and data-analysis strategies, with a focus on the coding of the interviews. Finally, it reflects on research challenges and points out possible future steps of the study.
