the rise of indigenous rights movements has led to controversy regarding the continuation of practices rooted in colonialism. such practices maintain the power relationship between the dominant culture and the indigenous culture, and can be seen as a form of cultural imperialism. such practices are seen as particularly harmful in schools and universities, which have the a stated purpose of promoting ethnic diversity and inclusion. in recognition of the responsibility of higher education to eliminate behaviors that creates a hostile environment for education, in 2005 the ncaa initiated a policy against "hostile and abusive" names and mascots that led to the change of many derived from native american culture, with the exception of those that established an agreement with particular tribes for the use of their specific names. other schools retain their names because they were founded for the education of native americans, and continue to have a significant number of indigenous students.
