PurposeThis article reports on a study around a further education, blended-learning program aiming to establish globally active professional learning networks (PLNs). The questions guiding the research were: (1) What levers and barriers to establishing viable networks are identified by its members? (2) What – if any – indications of knowledge transfer within the networks can be identified?Design/methodology/approachThe networking aspect of the study program was analyzed using semi-structured interviews with its recent participants and graduates (n = 22), with the objective of gaining insights into elements that supported the creation and maintenance of a global, student-centered network and community in the program. Additionally, a document analysis of the master theses of all participants since the start of the program (n = 96) was undertaken to look for indications of knowledge transfers from one cultural and/or geographical setting to another.FindingsBlending online exchanges with face-to-face exchanges was seen as helpful in establishing a sustainable network. Additionally, having a low-barrier communication platform where it was socially acceptable to not only communicate about professional but also informal matters was described by virtually all participants as a promoting exchange and cohesion. Furthermore, about a fifth of all analyzed master theses contained indications of knowledge transfer, with instances of incorporating models or concepts from other contexts being the most prominent occurrence.Originality/valueThe findings offer insights into establishing sustainable blended-learning networks. They elaborate on key elements that supported and hindered the creation and viability of such networks. Furthermore, they highlight the importance of formal but also informal spaces for exchange.
