Sierra Health Foundation is embarking on a new initiative to promote youth development practices among those who serve 'tweens and teens--youth who are ages 10 to 15. The initiative seeks to engage youth in a variety of contexts, including internships, service, social justice, and advocacy. A major part of the initiative focuses on expanding leadership opportunities for youth, the subject of this report. Sierra Health seeks to explore and highlight the topic of youth leadership because it is a critical tool for empowering youth to take control of their own lives and make healthier decisions that lead to success as adults. Sierra Health commissioned the Youth Services Provider Network to research and write this report as a part of both organizations' continuing efforts to publicize the importance of youth development approaches when seeking to improve the lives of youth. The Network is a collaborative of youth-service providers that strive to improve youth development practices throughout the Sacramento region through trainings, networking opportunities for youth agencies, and policy work. The goals of this paper are: 1) to provide an overview of youth leadership and why it is important; 2) to share some of the best practices from organizations that successfully implement youth leadership opportunities; and 3) to provide in a supplemental booklet an introductory catalogue of the youth leadership opportunities that exist in the greater Sacramento region. The report and catalogue aim to guide agencies that are interested in adopting youth leadership components into their program, to make youth aware of leadership opportunities in the Sacramento area, and to help Sierra Health identify gaps in youth services. The information in this report was gathered from many different sources, including interviews with and a survey of key organizations throughout the greater Sacramento region, as well as a review of the wide body of research literature and online resources addressing youth leadership in California and nationwide.
