Which of the following is a requirement for research facilities under the AWA?

Research facilities under the Animal Welfare Act (AWA) are required to conduct regular assessments of animal well-being to ensure that all animals are treated humanely and their needs are met. This includes evaluating their health, living conditions, and social interactions, which helps in maintaining high welfare standards in research settings. Regular assessments allow facilities to identify any potential issues early and implement corrective measures, thereby contributing to the overall well-being of the animals involved in research.

The other options do not align as directly with the core requirements set forth by the AWA. For example, while facilities may have breeding programs, there is no explicit requirement for them to provide a detailed breeding schedule. Similarly, the AWA does not mandate that an on-site veterinarian must be present at all times, although facilities must have access to veterinary care. Lastly, the AWA does not require public access to all research data, which is often subject to confidentiality and proprietary considerations. Thus, the correct answer emphasizes the importance of monitoring and improving the conditions and treatment of animals in research.
