Child Trends’ youth development team brings a multi-disciplinary perspective to its studies of adolescents and young adults and the programs that serve them. We conduct national and local evaluations of after-school, prevention, and other youth-serving programs. These evaluations examine whether programs are effective and how they work. We help programs develop logic models, conduct need assessments, and refine their performance management capacities. Our team also develops measures of adolescent and young adult well-being for indicator studies and evaluations nationally and internationally (see the Positive Indicators Project). The knowledge we generate is used by policymakers, funders, and programs to improve outcomes for youth as they transition to adulthood.
