Abstract
<jats:p>Research integrity is a key element of research quality, trust in science, and the effectiveness of science and innovation policy. It covers the entire research lifecycle: from the development of initial ideas and proposals to the conduct of research and the dissemination, use, and evaluation of research results. Our analysis of the U.S. experience has demonstrated the creation of a multi-level ecosystem for ensuring research integrity, in which the state provides incentives, the quality assurance system performs oversight, and the professional community establishes norms. The specific features of ensuring and evaluating research integrity in the United States have been identified, including the development of a comprehensive support system that combines integrated policies, educational programs and mentoring, preventive measures to raise awareness, the activities of specialized offices and committees, as well as a focus on ethical and responsible behavior in collaboration and proper management of data and publication practices. For the successful implementation of the evaluation of university research activities in the context of Open Science in Ukraine, it is necessary to analyze and generalize institutional practices for ensuring research integrity and the tools for its assessment.</jats:p>
