Funding for the SECCYD ended in 2009. However, the use and analysis of the data is ongoing.
The NICHD Study of Early Child Care and Youth Development (SECCYD) is a comprehensive longitudinal study initiated by the NICHD to answer questions about the relationships between child care experiences, child care characteristics, and children's developmental outcomes.
After a thorough scientific review of the Study concepts, the NICHD selected a research team, located at universities across the United States and at the NICHD, that together has provided multiple perspectives on and interests in child care research. This team of researchers has worked cooperatively to design and implement the Study and, in 1991, enrolled a very diverse sample of children and their families at 10 locations across the United States.
The major goal of the NICHD Study is to examine how differences in child care experiences relate to children's social, emotional, intellectual, and language development, and to their physical growth and health. Other goals of the Study include:
The NICHD SECCYD is characterized by a complex and detailed study design, which takes into account many variables, including characteristics of the child care and the family environment. Researchers are assessing children's development using multiple methods (e.g., trained observers, interviewers, questionnaires, and testing) and measuring many facets of children's development (e.g., social, emotional, intellectual, and language development; behavioral problems and adjustment; and physical health). This site provides listings of the instruments used, locations, and time of assignment for the assessments during:
Since 1991, the Study has followed the development of children from the time they were 1 month of age. It was conducted in four phases, based on the ages of the children when the information or data were collected. As children grew older, some families did not continue their participation in the study for different reasons (such as no longer interested, moved away, etc.), which explains why the number of children is not identical across data collection phases.
Analyses for the NICHD SECCYD are conducted by a network of investigators, the NICHD Early Child Care Research Network.
Major scientific decisions about the Study are reviewed and approved by the SECCYD Steering Committee, which includes an independent chairperson, one representative from each grantee site, one representative from the data center, and one representative from the NICHD. The Steering Committee has established policies and procedures that govern the operations of the Network, including its publication procedures. Further, the NICHD also monitors the progress of the Study.
An Advisory Board of leading scholars in the field of child development and health provides additional impartial oversight. The Advisory Board meets with the Steering Committee twice a year, during regular Steering Committee meetings.

All data from Phases I, II, III, and IV of the study are analyzed by the SECCYD researchers. The datasets are made available to other researchers for further analysis. Currently, datasets for all phases of the Study are available to qualified researchers (who will be affiliates to the Study).

The NICHD Early Child Care Research Network and affiliated researchers have an extensive listing of presentations and publications related to the Study and its findings. In general, these articles are geared toward scientists, researchers, and health care providers.
The NICHD also has a booklet for parents and families related to the SECCYD and its findings. You can view, download, or order a free copy of the booklet here.
