This brief report summarizes the results of the Earth Force program evaluation from the 2005-2006 school year. The report also provides a comparative view of the participant survey results from the past two years. Earth Force (EF) is a national nonprofit organization that operates programs that combine environmental education, civic education, and service-learning to help young people gain the knowledge, skills, and attitudes needed to become active environmental citizens in their communities. In 2005-2006, Earth Force operated three programs for in-school youth, the Earth Force Community Action and Problem- Solving (CAPS) Program, the original Earth Force service-learning and environmental education model; the Earth Force GREEN program, which focuses on watershed issues; and the Earth Force CHEC Program (Community History/Environmental Citizenship) which integrates local history and civics education to the regular Earth Force program. Earth Force also provides a separate set of program materials for after-school programs. Earth Force programs target middle school-aged youth, though local offices have developed a substantial number of sites in both elementary schools and high schools.
