There are many definitions relating to diversity, equity and inclusion that exist and sometimes the terms are used interchangeably. Definitions that are helpful in understanding the concepts are as follows:
Achievement gap refers to the observed disparity on a number of educational measures between the performance of groups of students, especially groups defined by gender, race/ethnicity, ability, and socioeconomic status.
Cultural competence is the key to thriving in culturally diverse classrooms and schools—and it can be learned, practiced, and institutionalized to better serve diverse students, their families, and their communities. Cultural competence is the ability to successfully teach students who come from a culture or cultures other than our own. It entails developing certain personal and interpersonal awareness and sensitivities, understanding certain bodies of cultural knowledge, and mastering a set of skills that, taken together, underlie effective cross-cultural teaching and culturally responsive teaching. —Definition from NEA (National Education Association)
Inclusion is defined as, “The active, intentional, and ongoing engagement with diversity—in people, in the curriculum, in the co-curriculum, and in communities (intellectual, social, cultural, geographical) with which individuals might connect—in ways that increase one’s awareness, content knowledge, cognitive sophistication, and empathic understanding of the complex ways individuals interact within systems and institutions” (AAC&U, 2009, ¶ 3). University of Arizona
Inclusiveness describes how people from all backgrounds are involved in the organization, how their perspectives are valued, and how their needs are understood.
Diversity can be defined as the sum of the ways that people are both alike and different. The dimensions of diversity include race, ethnicity, gender, sexual orientation, language, culture, religion, mental and physical ability, class, and immigration status. While diversity itself is not a value-laden term, the way that people react to diversity is driven by values, attitudes, beliefs, and so on. Full acceptance of diversity is a major principle of social justice. — Definition from NEA (National Education Association)
Diversity is the face of an organization.
