Who We Are

The ANSI National Accreditation Board is the largest multi-disciplinary accreditation body in North America.

We play an important role in ensuring the safety and quality of goods and services and in protecting the environment.

We accredit management systems and certification bodies, calibration and testing labs, forensic test and calibration service providers, inspection bodies, police crime units, reference material producers, and proficiency test providers. You wouldn't want to be treated by a doctor who isn't board certified in her specialty, or send your child to a college that isn't accredited, would you? Like those accrediting bodies, we conduct assessments to make sure our clients follow international standards and are competent to do their work.

The work we do helps facilitate international trade and eliminate the expense of redundant audits and tests.
