Controversial measures placing more pupils in each primary school class would only be temporary, the education chief promised yesterday. Director of Education Helen Yu Lai Ching-ping said the Government was determined to offer quality education in the form of whole-day schooling and 'the smaller class size will definitely be resumed'. But she did not say how long primary students and teachers would have to endure more cramped conditions after the new school year started in September. 'I cannot tell when the [smaller] class size will be resumed,' she said. 'Our priority is to offer whole-day schooling. This is also the wish of the general public. The Government is studying the time schedule to fully implement this. 'By 2002-2003, 60 per cent of primary students should be able to study in a whole-day operation school. We will examine the class size issue while planning whole-day schooling.' Seven major education bodies on Sunday united to condemn the department's plan to place an average of two more students in each primary class. They feared students would receive sub-standard education and teachers would have a heavier workload. Professor Rosie Young Tse-tse, chairman of the Education Commission, said having two more students in a class should not affect children's development too much. Quality education meant not only smaller class sizes but other measures such as whole-day schooling, she added. The Government will have to build 72 more primary schools to achieve the target of having 60 per cent of students learning in whole-day schools by 2002.
