A growing number of ethnocentric or culturally oriented niche charter schools have opened around the country. These ethnic or culture-oriented models raise legal and policy concerns about church/state entanglement as well as concerns about diversity. Indeed, there has already been litigation focused on racial and ethnic aspects of charter schools as well as religious influences.

Using legal research methods, this article examines the existing litigation involving culture-oriented charter schools and discusses the policy and legal tensions involved. (Contains 1 note.)
