United Nations Educational, Scientific and Cultural Organization (UNESCO) UNESCO-the United Nations Educational, Scientific and Cultural Organization-is a specialized United Nations agency that was founded on 16 November 1945. UNESCO promotes international cooperation among its 195 Member States and eight Associate Members to contribute to the building of a culture of peace, the eradication of poverty, sustainable development and intercultural dialogue through education, the sciences, culture, communication and information. UNESCO is the lead agency on sexuality education, developing tools and guidance such as the International Technical Guidance on Sexuality Education (2009) which are used by ministries and civil society in the development of sexuality education curricula, policies and implementation support. Technical support is provided at country and regional level to ministries of education and civil society organizations in their efforts to strengthen HIV and health education. The Population Council confronts critical health and development issues-from stopping the spread of HIV to improving reproductive health and ensuring that young people lead full and productive lives. Through biomedical, social science, and public health research in 50 countries, we work with our partners to deliver solutions that lead to more effective policies, programs, and technologies that improve lives around the world. Established in 1952 and headquartered in New York, the Council is a non-governmental, non-profit organization governed by an international board of trustees. www.popcouncil.org
