This article introduces a situational approach for assessing and teaching acculturation that captures how a person's level of competence and authenticity in a foreign cultural setting varies across the various situations the person encounters. Whereas previous research, such as the U-curve and Berry's dual identification model, portrays cultural adaptation at a broad, general level, the current approach provides a more nuanced perspective on acculturation by taking into account situational variability as well as variability in experienced competence and authenticity. The benefits of the framework for cross-cultural training and education are illustrated within the context of foreign MBA students in the United States. (Contains 1 note, 1 table, and 4 figures.)
