Most academic programs are now held accountable for measuring student-learning outcomes. This article reports the results of an assurance of learning (AOL) project designed to measure the impact of study abroad on the development of ethical reasoning, intercultural sensitivity, and environmental attitudes. The Association to Advance Collegiate Schools of Business International (AACSB) AOL guidelines (2007, 2008) are used to frame the overall assessment process. Hammer and Bennett's (2002) intercultural development inventory (IDI); Dunlap, Van Liere, Mertig, and Jones' (2000) new ecological paradigm; Forsyth's (1980) ethics position questionnaire (EPQ); and Richins' (1987) materialism scale are the primary measurement rubrics used in the study. Results support the proposition that study abroad does have a positive impact on the development of cross-cultural sensitivity and environmental attitudes. Although study abroad appears to have no direct impact on moral reasoning, changes in ethical reasoning do appear to be related to intercultural development and environmental attitudes. The AOL project demonstrates how assurance of learning programs can be extended to include experiential learning outcomes and can serve as a guide for the furthering of the globalization of a business curriculum.
