About Us
The TAY-Hub specializes in applied research and evaluation to inform the policies and practices affecting transition-age youth (TAY) with foster care experience.

We believe in a collaborative research process, and engage with the child welfare services community, young adults with foster care experience, and scholars across the country to ensure our research responds to the field’s most pressing needs. Housed within the California Child Welfare Indicators Project at UC Berkeley’s School of Social Welfare, we also maintain a public data portal that provides key insights into TAY outcomes in education and employment.

Our work builds upon the California Youth Transitions to Adulthood Study (CalYOUTH), the most comprehensive longitudinal study of TAY exiting foster care and California’s Extended Foster Care (EFC) Program. Since its start in 2012, the CalYOUTH study has provided crucial evidence on the outcomes of young people leaving care and the benefits of extended foster care.

Events & Convenings

In June 2024, we hosted the Transition-Age Youth Research & Evaluation Hub Convening at University of Southern California. During the event, recipients of the 2023-24 Research Subaward presented their findings to an audience of practitioners, policymakers, researchers, and individuals with lived experience in care, fostering an exchange of ideas. It featured four panels covering topics including accessing services, the importance of relationships and identities, policy implementation, and insights from lived experience.


Having researchers that can help to quantify, extrapolate, and provide that feedback to us in a way that we can digest and then be responsive to it and create policies and systems that can actually change in order to meet the needs of real children and families is invaluable.
