The Harold E. Jones Child Study Center is a research and educational institution for young children at the University of California, Berkeley. It is one of the oldest continuously running centers for the study of children in the country. The Jones Child Study Center has a special relationship with the Institute of Human Development as a site for research, training and outreach to the community, parents, and teachers. The Institute of Human Development's fundamental mission is to study evolutionary, biological, psychological, social, and cultural factors that affect human development from birth through old age. Research conducted at the Institute of Human Development and the Jones Child Study Center is interdisciplinary: psychology, education, social welfare, architecture, sociology, linguistics, public health, and pediatrics. The primary audiences for the findings include scholars and parents. Faculty, postdoctoral, graduate, and undergraduate students observe and test children attending the preschool for their research projects. Undergraduate students in Early Childhood Education may also gain experience in the classrooms as teachers' assistants.
