One of the challenges facing Hong Kong schools is the growing cultural diversity of the student population that is a result of the growing number of ethnic minority students in the schools. This study uses semi-structured interviews with 12 American, Canadian, Indian, Nepalese and Pakistani teachers working in three secondary schools in the public sector to examine how school teachers are handling this challenge. The study uses these interviews to establish a model for the creation of culturally responsive environments that may help to improve the academic performance and promote the personal growth of students in Hong Kong's secondary schools. Five aspects of cultural responsiveness are identified: conceptualising cosmopolitanism, raising sensitivity to ?minor acts of racism?, managing the diverse learning needs of students, promoting a deep understanding of cultural values and helping students deal with the challenges of trilingualism. This study argues that ethnic minority teachers are engaged in a continuing cross-cultural process through which they make sense of the cultural diversity of students and re-learn their own beliefs and practices. The implications for the creation of a culturally responsive environment are also presented.[Copyright of Asia Pacific Journal of Education is the property of Routledge.
