This is an adaptation of the Youth Participation Guide: Assessment, Planning, and Implementation published by Family Health International (FHI) in 2005, in collaboration with Advocates for Youth. This 2008 publication is supported by the United Nations Population Fund (UNFPA) through a contribution from the United Nations Population Fund (UNFPA) and the Government of Finland. Revisions and adaptations were implemented by Marija VasilevaBlazev (UNFPA). Dr. Aleksandar Bodiroza (UNFPA) provided technical oversight and guidance. The UNFPA plans to use this tool within their youth programmes in general; for the project, Improving the Sexual and Reproductive Health in Adolescents and Young People in the Central Asian Republics, Belarus, Moldova and Ukraine; and for the Youth Peer Education Network (Y-PEER) programme in particular. The opinions expressed in this document do not necessarily reflect the policies of UNFPA and/or the Government of Finland. UNFPA is an international development agency that promotes the right of every woman, man and child to enjoy a life of health and equal opportunity. UNFPA supports countries in using population data for policies and programmes to reduce poverty and to ensure that every pregnancy is wanted, every birth is safe, every young person is free of HIV/AIDS, and every girls and woman is treated with dignity and respect. Y-PEER, the Youth Peer Education Network, is a groundbreaking and comprehensive youthto-youth initiative pioneered by UNFPA. Y-PEER is a network of more than 500 non-profit organizations and governmental institutions; its membership includes thousands of young people who work in the many areas surrounding adolescent sexual and reproductive health. The network, which is constantly expanding, consists of youth from Central and Eastern Europe, Central Asia, the Middle East, Gulf Cooperation Council (GCC) countries, North and East Africa, and recently initiated in Brazil and Chile.
