Contrary to the myth that "every parent thinks her child is gifted," (whether he or she is gifted, or not) parents are highly effective identifiers of high ability in their children (Robinson and Robinson 1992); indeed, they are significantly more accurate than teachers, who are rarely trained in how to identify and respond to gifted students and who may not notice high academic ability if they present the gifted child only with work set at the level and pace of the average child in the class (Jacobs 1971).
