The Institute for the Study of Advanced Development (ISAD), is a not-for-profit, tax exempt 501(c)3 corporation, founded in 1986 to conduct scientific research and redefine giftedness. Historically, giftedness was seen almost exclusively as academic achievement or the potential for recognition in adulthood—external manifestations. We view giftedness from the inside-out as a qualitative difference in inner experience throughout the lifespan.


ISAD brought overexcitabilities into the mainstream consciousness of the field; developed the visual-spatial learner concept; established national policies on the assessment of twice exceptional learners; and created a vehicle for understanding giftedness in adults. Our journal, Advanced Development, is the only journal on adult giftedness. It presents a new vision of giftedness in adults related to values:  empathy, responsibility, integrity, autonomy, authenticity, moral courage, commitment, and harmony. We soon will be offering qualified researchers and graduate students access to our extensive research data.
