Which statement is correct regarding NDT Level III Practical Examinations?

The correct statement highlights that the exam administrator must hold a valid ASNT Level III certification, underscoring the importance of having a qualified individual oversee the practical examinations. ASNT Level III certification signifies a high level of expertise and understanding of non-destructive testing (NDT) methods, standards, and processes. This requirement ensures that the administrator can effectively evaluate the candidates' practical skills and knowledge, maintaining the integrity and quality of the examination process.

In contrast, options suggesting that any NDT technician can conduct the exams or that no prior certification is necessary for the administrator fail to acknowledge the specialized knowledge required to accurately assess Level III candidates. The integrity of the certification process relies heavily on the expertise of the administrator.

Furthermore, while it is possible to have multiple individuals involved in the examination process for various roles or types of assessment, the statement regarding a single qualified administrator aligns with standard protocols to ensure consistency and authoritative evaluation. Thus, having a certified Level III professional as the exam administrator establishes a necessary standard of proficiency and credibility in conducting practical examinations.
