Who is responsible for the certification of a company's NDT personnel?

The responsibility for the certification of a company's NDT personnel primarily lies with the employer. This is established by industry standards and practices set forth by organizations like the American Society for Nondestructive Testing (ASNT) and any applicable regulatory bodies. Employers must ensure that their personnel are adequately trained and certified according to the relevant standards and specifications for the methodologies they perform. This includes validating the qualifications of their staff and maintaining records of their certifications.

While outside services can assist in the certification process and individual personnel may also take an active role in pursuing their certification, it is ultimately the employer's duty to ensure compliance with those standards. Regulatory bodies may set the overarching guidelines and standards for certification, but they do not directly certify personnel; instead, they oversee the processes and standards that employers must follow to ensure qualified personnel.
