In 2006, 4-H National Headquarters and National 4-H Council introduced an initiative aimed at increasing the number and quality of science, engineering, and technology programs that 4-H offers around the country, and increasing the number of youth involved in these programs. By engaging youth in informal science educational opportunities through the 4-H Science Initiative, the organization hopes to increase science interest and literacy among youth, the number of youth pursuing post-secondary education in scientific fields, and the number of youth pursuing science-related careers. This report examines attitudes towards science held by youth in 4-H Science programs around the country. With the support of the Noyce Foundation, National 4-H Council has been working with Policy Studies Associates (PSA) since 2009 to evaluate the implementation of this initiative. Evaluators have examined state- and county-level implementation and delivery of science programming; youth engagement in science, attitudes towards science, and knowledge of science; and promising practices used in science programs. The goals of this report are to describe the characteristics and opinions of youth in 4-H Science programs around the country as of 2013 and to illustrate the potential effects of 4-H Science programs on youth. These descriptions of youth are intended to inform 4-H about the youth it is serving and to help identify areas where improvement and support may be needed. (author abstract)
