This report considers lessons learned from a multi-part research investigation into United States Agency for International Development's (USAID) civic education programming. To better understand how and under what conditions civic education contributes to the development of a more active and informed democratic citizenry, USAID initiated the study in the Dominican Republic, Poland, and South Africa to measure the impact of adult and school-based civic education programs focusing on participants' democratic behaviors and attitudes. Results show that civic education programs for adults can have a significant, positive impact on certain key aspects of democratic behaviors and attitudes. Civic education appears to contribute to greater rates of political participation among program participants, particularly at the local level. Civic education programs appear to have minimal effect on changing democratic values, such as political tolerance, and, in fact, appear to have a negative impact on some values, such as trust in political institutions. Findings for school-based civic education programs mirror those for adult programs, although the impact of civics training was generally weaker and more inconsistent for students than for adults. The key finding to emerge, applying to both adult and school-based programs, was that course design and quality of instruction are critical to the success of civic education programs. The report has six parts: (1) "Introduction"; (2) "Civic Education, Democracy, and USAID's Approach" (School-based Civics Programs; Adult Civic Education; USAID Programs; Key Variables in Civic Education Programs); (3) "Report Findings" (Adult Findings; School Findings); (4) "Recommendations and Lessons Learned"; (5) "Conclusion"; and (6) "Want to Know More?"
