The main purpose of this legislation, known as the "Train More Nurses Act," is to enhance the nursing workforce in the United States. It aims to address the growing need for nurses by evaluating existing grant programs that support nursing education and workforce development. Key provisions of the Act require the Secretary of Health and Human Services and the Secretary of Labor to conduct a thorough review of all grant programs related to nursing. They must report their findings to Congress within one year of the law being enacted.
