Science-based performance standards offer a viable means of reducing regulatory burden while ensuring that research animal welfare and high-quality research data are realized. Unlike rigid regulations, science-based performance standards evolve as new information becomes available, thereby allowing new discoveries to be implemented in a timely manner and in a way that more effectively benefits the animals and the science. The implementation of performance standards requires a well-coordinated institutional team composed of the administration, research staff, the institutional animal care and use committee, professional and technical animal care personnel, occupational health and safety staff, and physical plant staff. This animal program team is best supported in an institutional environment that reflects a culture of care, compliance, and responsibility. In such a culture, the professional judgment exercised by the team is well grounded in meeting the diverse needs of the program's customers, who include the animals, the researchers, and research stakeholders such as the public. The institutional culture of care, compliance, and responsibility fosters workplace integrity, an ethics-based decision-making paradigm, sound understanding of institutional expectations through good communication and clear lines of authority, the hiring and retention of trained and well-qualified individuals, and a system for continuous development and improvement of the program.
