The National Association of Testing Authorities (NATA) is Australia's leading accreditation body, ensuring the competence and compliance of laboratories, inspection bodies, calibration services, and proficiency testing providers. Established in 1947, NATA plays a pivotal role in the nation's quality infrastructure by accrediting organizations across various sectors, including healthcare, construction, and environmental services. Through its rigorous assessment processes, NATA ensures that services provided by accredited bodies meet international standards, thereby fostering confidence in the reliability and accuracy of test results and calibrations.

NATA operates under the auspices of the Australian Government and is a not-for-profit organization. It works in close collaboration with government agencies, industry stakeholders, and other accreditation bodies to promote global harmonization of standards. NATA's accreditation services encompass a wide range of fields, including medical testing, forensic science, pharmaceuticals, and engineering. By providing these services, NATA supports public safety, consumer protection, and trade facilitation, ensuring that Australian goods and services are recognized for their quality both domestically and internationally.

To maintain the highest standards of accreditation, NATA regularly reviews and updates its assessment criteria in line with international best practices. It is a member of the International Laboratory Accreditation Cooperation (ILAC) and the Asia Pacific Accreditation Cooperation (APAC), through which it participates in mutual recognition arrangements. These arrangements enhance the acceptance of Australian test and calibration results globally, reducing technical barriers to trade.
