GIFTED children may soon be given their first chance to develop to their full potential when a pilot scheme is introduced into primary schools. In September, 40 teachers will be on the lookout for signs of advanced ability and potential genius among children in 19 schools across the territory. The teachers have completed the first stage of training to allow them to pick out gifted and talented children. They will look for behavioural signs of giftedness. These could range from advanced ability to restlessness indicating the child may be bored with lessons that are too easy. The scheme is part of the Government's answer to criticism that Hong Kong is behind the rest of the world in its ability to advance gifted youngsters. In an effort to catch up, a study is being conducted which will determine the best way forward. This weekend, the seven-strong executive committee of the World Council on Gifted and Talented Children is visiting Hong Kong to look at the facilities at the Exhibition Centre - the venue for next year's 11th World Conference on Gifted and Talented Children. They will also be overseeing a day of lectures and workshops at the University of Hong Kong today for parents, teachers and interested parties on the subject. Dr Raymond Wu, a member of the organising committee, said although Hong Kong was economically developed, it was only at the developing - if not under-developed stage - as far as gifted children were concerned. The scheme will be phased in during the next three years, initially in primary three, four and five, and later primary one, two and six. Youngsters thought to belong to the estimated two per cent of children who are gifted can then be encouraged to advance quickly through the school system. ''All our children deserve the best education that we can offer,'' said committee member Maureen Robinson. ''A lot of resources have been put into helping children at the other end of the scale but now it is time to help the gifted ones as well,'' she said.
