Schools will have to wait longer than expected before learning whether they can teach in English next academic year. Secretary for Education and Manpower Joseph Wong Wing-ping yesterday announced the appointment of barrister Benjamin Yu to the appeals committee on medium of instruction. Mr Yu said he did not think the committee could finish reviewing all 20 appeals this month. The Education Department has said schools would be told the outcome of their appeals by the end of January. But Mr Yu said: 'I don't have such an expectation. I don't think we can finish the job this month. But we will work hard. 'I am an outsider in the education sector. I hope to contribute to the committee from the legal angle, to ensure the procedure is fair.' Professor Chang Hsin-kang, president of City University, and Professor Amy Tsui Pik-may of Hong Kong University also sit on the three-member committee. Chan Yick-man, chairman of the Parent Teachers' Association at Cheung Sha Wan Catholic Secondary School, one of the schools which is appealing, said Mr Yu's appointment should help the committee work fairly. But he was disappointed that results were unlikely this month. 'The later the schools are told of the results, the less time they will have to prepare for teaching materials for the coming school year,' he said. Mr Yu graduated from St Joseph's College, which has been approved to teach in English. His appointment came after two members of the committee volunteered to step down amid fears of a conflict of interest.
