Gifted pupils: too many are just ordinary, say teachers

UK news story from earlier this month:

Ministers are overestimating the number of exceptionally bright pupils in Britain's schools, the World Council for Gifted and Talented Children will be told this week.
Research shows that teachers charged with picking out the top pupils feel that far too many are labelled as 'gifted and talented' and that the government was wrong to recommend that 10 per cent were picked out in each school, a total of 800,000 across the country. Instead, between 2 and 5 per cent of children should be classed as 'gifted learners', cutting hundreds of thousands of pupils already placed in the top group.
