Welcome to the National Children’s Study Archive!

The National Children’s Study (NCS), authorized by the U.S. Congress in 2000, under the Children's Health Act, was designed to be a longitudinal study of environmental health effects on children; however, the Study was ended in 2014 by the National Institutes of Health. The NCS Archive assembles the knowledge and experience gained from the NCS to serve as an ongoing resource to inform future child health and development research. It provides access to data collected from more than 5,000 children and their families who participated in the NCS Vanguard Study between 2009 and 2014.

Registered users will have access to several additional resources to promote and cultivate new ideas for further exploration of existing NCS data. Several sets of de-identified Study visit data are available for researchers to explore, as well as search tools for defining and connecting Study protocol and data elements.

Registered users can propose new research projects leveraging available NCS data. Projects and proposals are tracked and managed with an easy-to-use online system. Researchers with approved projects will be able to analyze NCS data on secure virtual workstations within a supported Researcher Portal.
