Quality Portal - Overview

The National Institute of Standards and Technology (NIST) helps ensure that U.S. organizations (and their products and services) achieve the highest levels of quality through efforts including the Baldrige Performance Excellence Program (BPEP), the National Voluntary Laboratory Accreditation Program (NVLAP), calibration services, the production of reference materials and data, and by maintaining and transmitting accurate measurements to state agencies and industry.
