For Tony Chiu Sin-wing, head of an organisation that owns 15 profit-making preschools, a switch to non-profit status would probably ensure survival of his schools. Mr Chiu, of Sun Island English Kindergarten and Child Care Centre, said he hoped the Education and Manpower Bureau would assist the transition of his schools to the new status. The schools, charging an annual fee of less than HK$20,000, are at present excluded from the school voucher scheme announced by the chief executive last week. Mr Chiu said shareholders might suffer from the change of status but there was no alternative when competition among preschools was intensifying. 'There won't be much disruption to the operation of the schools,' he said. 'The profit margin is already very narrow.' Angela Luk Chiu Kwan-hung, supervisor of Creative Kindergarten, said she had decided to apply for non-profit status before the announcement of the voucher scheme, adding that the scheme would benefit parents. But Cheung Lai-wah, head of a Tseung Kwan O preschool, said she would not consider switching to non-profit because it 'entails many difficulties', including uncertainties about wage levels and rent reimbursement. Limits on profits were also a concern, she said.
