All social innovators aim to create change in the world, but how can you be sure that you have created your intended change? In other words, how can you concretely define that change, and then effectively measure it? In this course you will learn the why, what, when, who, and how of social impact measurement. You will learn the language of both monitoring and evaluation, be introduced to some of the tools used for each, and practice assessing the trade-offs of tool and method selection. For example, what level of rigor is necessary for evaluating your social enterprise? What role should technology play? What practical considerations are there in selecting an approach? As a final deliverable for this course, you will have built a logic model, indicators, and a corresponding survey instrument for your social enterprise.
