This study addressed the research question: How do Vietnamese principals lead the professional learning of teachers? The research was comprised of a multiple-site case study of leadership and teacher learning in four Vietnamese schools. Qualitative data analysis aimed at identifying modal practices adopted by these Vietnamese principals to lead teacher learning in their schools. The research identified four key leadership practices: moral purpose, collaboration, learning support, and motivational strategies. The findings support assertions for a broad set of globally-relevant school leadership practices as well as the need to adapt these to the cultural context of specific schools. © 2017 Informa UK Limited, trading as Taylor & Francis Group
