Under SNT-TC-IA, certification of visual NDT personnel is the responsibility of:

• A. The NDT Level III
• B. The employer
• C. ASNT
• D. An outside agency

Answer: (B)

Under SNT-TC-IA, the entity that certifies NDT personnel is the employer. The standard is a recommended practice that lets employers establish their own written certification program, including qualification requirements, testing methods, and records, and then issue certificates to personnel who meet those criteria. The Level III's role is to oversee and validate the program— approving procedures, assessing performance, and ensuring the system works— but the actual certification issuance rests with the employer according to the written practice. The ASNT provides the framework and guidance, not direct, universal certification of individuals, and outside agencies would only be involved if the employer specifically contracts them; the default responsibility lies with the employer.
