A slide show to present the Heifer Impact Evaluation Model, lessons learned from its application in the past five years, and a reflection about its relevance to the field of international development as an alternative to experimental designs.Heifer International has reached millions of families in 125 countries providing training and livestock to help people improve their livelihood. Heifer funds individual projects through local organizations in reaching resource-poor families. Since 2005, the Western Michigan University Evaluation Center has conducted impact evaluations of Heifer operations in 20 countries. The Center developed the Heifer Impact Model for evaluating three levels of impact (family/community, beyond the community and individual/group values) based on six value groups: meeting basic needs; livestock care and management; environmental care and management; education for a just/sustainable world; empowerment of family and community; and systems and policy improvements. A qualitative and quantitative approach has been used to assess 103 variables in each project. #Development #2009Conference #Chianca #Impact #WMU #Heifer #international #InternationalandCross-CulturalEval #Scriven #Evaluation2009 #Poverty
