AAHRPP accreditation signifies that a human research protection program (HRPP) meets rigorous standards for ethics, quality, and protection of research participants. Organizations earn the right to display the AAHRPP seal by demonstrating their commitment to scientifically and ethically sound research and to continuous improvement.

The AAHRPP seal offers assurances that an HRPP is focused first and foremost on excellence—and is a preferred partner for clinical trials and other types of multisite research.
