摘要：Extension educators have been challenged to be cost effective in their educational programming. The cost effectiveness ratio is a versatile evaluation indicator for Extension educators to compare the cost of achieving a unit of outcomes or educating a client in similar educational programs. This article describes the cost effectiveness ratio and its application in Extension. The major implications are 1) learning ways to reduce the cost of educational programming, 2) making Extension educators aware of the cost of educational programming and guiding ways to maximize the cost effectiveness, and 3) promoting pro-evaluation organizational culture.
