Final answer:
The Environmental Protection Agency (EPA) is the U.S. agency responsible for administering water quality standards, while the specific agency for certification examinations varies by field.
Step-by-step explanation:
The statement as presented is incomplete and does not specify the context or the national agency it refers to, making it impossible to determine its truthfulness. Different certifications are administered by various national agencies depending on the professional field. However, with respect to environmental certifications and standards, particularly water quality standards, it is the Environmental Protection Agency (EPA) that is responsible within the United States. The EPA develops and enforces regulations that help ensure that water contaminants are within safe limits. Other options such as the national air and space administration, the president of the United States, and the forest service have different mandates and roles.
