Some technical and pre-vocational school teachers fear they may lose their jobs or have to teach subjects they are not qualified for because of a new curriculum. More than 200 teachers and principals voiced concerns yesterday at a seminar organised by the Hong Kong Institute of Education on the future of pre-vocational and technical teaching. The Education Department last month released a report suggesting the schools should update their curriculum within two to three years. Schools should have stronger emphasis on language and business subjects, it was recommended. Ronald Lau Yiu-fai, chairman of the Hong Kong Pre-vocational Schools Council, said yesterday it had received about 200 inquiries from teachers worried about their careers. 'Since more language and business subjects will be added, some technical subjects such as metalwork or car-repairing might have to be dropped. 'Teachers of those technical subjects fear they would be forced to teach language or other subjects. They are worried they cannot adapt to such a change,' Mr Lau said. The report also suggested schools could drop their specific 'technical' or 'pre-vocational' references from their names to get rid of their inferior image. But Mr Lau doubted whether the move would help. He said parents might then not know whether the school emphasised technical teaching.
