It's the policy of the University of Northern Colorado that research involving human subjects must be approved by the Institutional Review Board (see University Regulation 3-8-104). This policy applies to UNC faculty, students and staff. The major responsibility for maintaining ethical standards and protecting human rights rests with individual researchers and research advisors.
The Institutional Review Board offers an added measure of assurance and serves as a local resource for the interpretation of ethical guidelines. You can read more about UNC policy governing research with human beings on the Office of Research website.
