Gesell Institute of Child Development is a 501(c) 3 non-profit organization that, since 1950, has been a leader in researching and teaching about how young children learn and grow.

Our mission is to promote the principles of child development as the basis for all decision making for young children.

Our vision is that all children enjoy their childhood, and that they have the time and opportunity to grow and to learn at their own pace and in their own way.

Gesell programs, publications, and research efforts help parents, educators, psychologists, social workers, and medical professionals understand the ages and stages of childhood. Understanding the stages of growth and development, and using this knowledge to interpret behaviors is essential to meeting the unique learning needs of young children in all settings. Gesell workshops, seminars and materials link the continuum of growth and development to a variety of practical applications, including the use of an effective screening measure, the Gesell Developmental Observation-Revised(GDO-R) and the Gesell Early Screener (GES).
