Early intervention is a series of service models which aim to overcome or transcend diversity to provide opportunity, equality and excellence in gifted preschoolers' education. The experiences of early intervention can powerfully exert impact on attitudes toward learning confidence and later ambitious achievements for all young gifted children. For optimal development of gifted preschoolers with individual special needs, including the handicapped, cultural diversity and socio-economic disadvantages can be enhanced with intervention at an early age. This research attempts to investigate, by utilizing literature review methodology which yields themes relating to research background and implementation necessary, how early intervention affects the developmental success for young gifted children.
