The Youth Villages Transitional Living Evaluation is testing whether the Transitional Living program, operated by the social service organization Youth Villages, makes a difference in the lives of young people with histories of foster care or juvenile justice custody. The program, which was renamed "YVLifeSet" in April 2015, is intended to help these young people make a successful transition to adulthood by providing intensive, individualized, and clinically focused case management, support, and counseling. The evaluation uses a rigorous random assignment design and is set in Tennessee, where Youth Villages operates its largest Transitional Living program. From October 2010 to October 2012, more than 1,300 young people were assigned, at random, to either a program group, which was offered the Transitional Living program's services, or to a control group, which was not offered those services. Using survey and administrative data, the evaluation team is measuring outcomes for both groups over time to assess whether Transitional Living services led to better outcomes for program group youth compared with the control group's outcomes.
