NVLAP is an accreditation program administered by which entity?

• A. The National Institute for Occupational Safety and Health
• B. The National Institute of Standards and Technology
• C. The Occupational Safety and Health Administration
• D. The Proficiency Analytical Testing program

Answer: (B)

NVLAP stands for the National Voluntary Laboratory Accreditation Program and is administered by the National Institute of Standards and Technology. NIST is the U.S. agency that develops standards and maintains measurement quality, and it runs NVLAP to certify that laboratories performing testing, calibration, and related activities are technically competent and operate under appropriate quality management. The other organizations listed have different roles—NIOSH focuses on occupational safety research, OSHA enforces safety regulations, and the Proficiency Analytical Testing program is a separate proficiency-testing provider, not the accrediting body.
