This paper introduces a model to guide the process of designing and evaluating study abroad programs, addressing particular stages and influential factors. The main purpose of the model is to serve as a basic structure for those who want to develop their own program or evaluate previous cultural immersion experiences. The model is based on the existing literature, actual experience in designing short-term programs, and on the theoretical evaluation principles of Appreciative Inquiry (Dunlap 2008) and Logic Models (Renger and Titcomb 2002).
