THE Education Department has doubled to 16 the number of lines for its automatic telephone enquiry system to provide better and more efficient service to the public. The 24-hour enquiry service (2891-0088) came into operation in February 1993. The service is bilingual and callers can obtain the type of information they require by following the voice instructions in the system. A spokesman for the department said the extra lines would make it easier for the public to get information on educational services. 'The subjects covered include Primary One admission, student and careers guidance, application for supply teaching posts, special education service, student guidance, choosing a school, teacher registration, withdrawal of Provident Fund, non-graduate teacher qualification assessment and teacher mortgage interest subsidy scheme,' the spokesman said. 'The system will also be used to make important announcements such as the suspension of school during typhoons or rainstorms.'
