“…In response to “the complexity of the work of education and the wide variability in outcomes that our systems currently produce” (Bryk, 2015: 467), school-to-school collaboration has become increasingly prevalent in K-12 education across the world over recent years (Azorín and Muijs, 2017; Chapman and Hadfield, 2010; Muijs et al, 2010; Sliwka, 2003). A set of studies have discussed the policies and practices of school networks and collaboration in different educational systems such as Belgium (Feys and Devos, 2015), Chile (Pino-Yancovic et al, 2020), Germany (Schulz and Geithner, 2010), Portugal (Lima and Dâmaso, 2019), Spain (Azorín and Muijs, 2017; Díaz-Gibson et al, 2017), the United Kingdom (Chapman, 2008, 2015; Dudley, 2011; Katz and Earl, 2010; Muijs, 2008), and the United States (Bryk, 2015; Proger et al, 2017; Wells et al, 2015; Wohlstetter et al, 2003, 2015), etc. These studies have suggested that school-to-school collaboration has several advantages such as (a) exchanging ideas, knowledge, and resources, (b) providing mutual support and challenge, (c) promoting professional development, and (d) facilitating innovation (Chapman, 2015; Chapman and Muijs, 2014; Keddie, 2014; Moore and Rutherford, 2012; OECD, 2003; Pino-Yancovic et al, 2020).…”
