NON-ACADEMIC subjects and extra-curricular activities may be used to assess primary and secondary school pupils under new proposals by the Education Commission. The commission chairman, Professor Rosie Young Tse-tse, said yesterday the commission would look at ways of introducing a fairer mechanism to judge pupils' achievements. The system based mainly on examinations was neither adequate nor fair, Professor Young said. The commission's working group on education standards was studying whether overseas assessment mechanisms could be applied to Hong Kong, or if it was necessary to ask local experts to establish their own system for Hong Kong. Legislator and commission member, Cheung Man-kwong, said the assessment could also look at the non-academic performance of students and it might be best to develop separate tests for each individual school. But he admitted it would be difficult to work out an accurate mechanism. ''At present, there are assessments like the Hong Kong Certificate for Education Examination for Form Five students and the internal attainment tests on the pupils' performance in Chinese, English and Mathematics at all levels. ''But the attainment tests are not very accurate as the Education Department usually just gives a broad guideline for the teachers marking the tests. So the results will vary, according to how the tests are marked,'' he said. Professor Young said the three working groups on language proficiency, education standards and school funding would submit a report around May.
