It is important to recognize that many years of research has been conducted to define the terms used in globalization, and that "intercultural competence," "global competence," and "global citizenship" all have different meanings and scope. As communication and interaction across the globe happens more readily all the time, it is important to have and to utilize clearly defined jargon to increase message clarity and interpretation.
Intercultural capacity is a subset of global competence, which can also be referred to as "global competency." At the pinnacle of Darla Deardorff's Pyramid Model of Intercultural Competence (2006) is the ultimate intention of treating others the way in which they wish to be treated. Interactions are cross-cultural, meaning exchanges with another culture; however the scope is not across the entire world. Additionally, global competence expands to include additional dimensions such as self-awareness, risk taking, global knowledge, and collaboration. As a model of competence should not include another dimension of "competence," the Global Competence Model™ uses the variant "Intercultural Capability" to reflect this aptitude and avoid confusion.
Global citizenship imparts a new layer of complexity, and since "global" is part of both terms, it is critical to use the appropriate terminology to communicate one's intentions. Global citizenship is a broad term that encompasses the humanitarian component of taking care of the world and its inhabitants. Global issues such as the environment, the availability of clean water, the spread of HIV/AIDS, world hunger and famine, social justices, etc. are all significant causes that warrant the attention of all citizens of the world. Addressing these important matters effectively often requires additional functional skills and knowledge in fields such as environmental science, engineering, medicine, or nutrition, and such capability is a step beyond global competence. Therefore, global competence is not global citizenship; however, to be a global citizen, one DOES need to be globally competent.
