Who may conduct grade examinations for Level I and Level II personnel?

The ability to conduct grade examinations for Level I and Level II personnel is specifically designated to a selected representative of the NDT Level III. This is because the NDT Level III individual possesses the requisite knowledge, experience, and authority to evaluate the qualifications and performance of Level I and Level II technicians according to established standards and procedures. The NDT Level III is trained and certified to assess not only technical skills but also adherence to safety and quality protocols within the non-destructive testing (NDT) field.

The inclusion of a Level III in the grading process ensures that the evaluations carry the appropriate weight and credibility necessary for maintaining the integrity of the certification process within NDT practices. This role is critical for upholding the standards set by relevant organizations and ensuring that personnel are adequately trained for their respective tasks.

The other options do not possess the same level of authority or specialized training required for conducting these examinations. For instance, a third-party examiner may not have the specific qualifications or closeness to the organization's NDT practices necessary for such evaluations. Similarly, a licensed technician or a peer technician, while skilled, would lack the designated oversight capabilities of a Level III, making them unsuitable for officially grading Level I and Level II personnel.
