Many tribal communities have their own IRB. The Navajo Nation established a Human Research Review Board in 1995. The Navajo Nation's Council enacted a research code developed to protect the privacy and interests of their culture. All data resulting from research in the nation remains the property of the Navajo. They have a rigorous approval process requiring support from the community, progress reports, a final report, presentation at an annual conference and community feedback at the conclusion of the study and prior to publication. Publication of the research requires approval of the manuscript including required changes before publication. Contact the IRB if your research involves Native Americans.
