“…First, RPO's positive impact on collaborative school culture can be explained because RPO enables the creation of collaborative professional relationships in practice, that is, progressing from a collaborative discourse to a collaborative action, and thus promoting schools in which educators work together and learn from one another, sharing goals and values about teaching to meet the school educational challenges (Corcelles‐Seuba et al., 2022; O'Leary & Savage, 2020). Using the validated TCPQ instrument and a pre/post research design, our research contributes to reinforcing previous results obtained from qualitative studies that reported an increase in teachers' collegiality after RPO intervention (Arnau et al., 2004; Hamilton, 2013; Motallebzadeh et al., 2017; Rosselló & de la Iglesia, 2021; Sider, 2019; Slater & Simmons, 2001).
