CalYOUTH is an evaluation of the impact of the California Fostering Connections to Success Act on outcomes during the transition to adulthood for foster youth. CalYOUTH includes collection and analysis of information from three sources: 1) transition-age youth, 2) child welfare workers, and 3) government program data. The study, directed by Dr. Mark Courtney at the University of Chicago and conducted in collaboration with the California Department of Social Services and County Welfare Directors Association of California (CWDA), was carried out over a 5-year period from 2012–17.
