This article focused on the necessary ingredients to become an accomplished adult for nation building. The processes of becoming an accomplished adult as a panacea to any national development cannot be overemphasized. Renzulli’s three - ring conception of giftedness is used as a model for the accomplishment in adulthood. According to Renzulli giftedness does not exist in a vacuum, but what make an individual to become gifted? To become a gifted person based on extensive research on creative productive individuals requires three criteria: the above average ability, not necessarily superior, commitment and creativity in that domain. The application, taxonomy of behavioural manifestations of giftedness and preparation time required for attaining adult accomplishment are discussed. The paper concluded that to become an accomplished adult involves composite set of traits and that if all the constraints are negotiated, adult accomplishment will be of greater impact for national development. Recommendations are made on how these early discoveries of giftedness can be encouraged supported and developed to become accomplished adult for national development.Keywords:
