Who We Are

The ANSI National Accreditation Board (ANAB) 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 the full spectrum of conformity assessment bodies. 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.
