This case study explored how the principles of multicultural and intercultural education are reflected in a minority-majority Hong Kong secondary school (that is, a school where most students are ethnic minorities). The findings suggest that the school illustrates several aspects of multicultural and intercultural education, especially content integration, prejudice reduction, equity pedagogy, and democratic deliberation, particularly in relation to school-based material, teacher sensitivity, and dialogical reasoning. The main hurdles discovered are language learning difficulties and an unsupportive social environment. This study contributes to literature on the development of multicultural and intercultural education in Hong Kong and offers directions for generalizable future research. Copyright © 2023 Peicong MA et al.
