Welcome to the website of CMI Support Centre, an electronic network for supporting teachers using Chinese as the Medium of Instruction (CMI) in Hong Kong. Following Hong Kong Education Department's Firm Guidance on Medium of Instruction issued in early 1997, the majority of secondary schools in Hong Kong switched from English to Chinese as the medium of instruction starting from September 1998. To support the newly switched CMI teachers in the aspects of language and teaching innovations to cope with the change, the CMI Support Centre was set up in September 1998 by the Department of Curriculum Studies of the University of Hong Kong. The Centre was sponsored by the Standing Committee On Language Education And Research (SCOLAR) from 1998 to 2000 and is now sponsored by Quality Education Fund (QEF). CMI Network is one of the significant output of the Centre to serve CMI teachers.
