 Under such a system, the government is only in charge of the school curriculum and teaching personnel while the lands still belonged to the schools.While Chinese primary schools were allowed to retain Chinese as the medium of instruction, Chinese secondary schools are required to change into English-medium schools.Over 60 schools converted to become National Type schools, including famous schools like Chung Ling High School, Penang Chinese Girls' High School on Penang Island, Jit Sin High School, and Ave Maria Convent High School, Sam Tet High School.While the medium language for most subjects is switched to English as according to the proposal, the teaching and learning of Mandarin remained compulsory in these schools, with most of them dedicating at least one seventh to one fifth of their teaching time per week to Mandarin studies.
