Which of the following is true about the qualifications of Level III, Level II, and Level I in SNT-TC-1A?

The qualifications for Level III meet or exceed those of Level II because Level III is recognized as the highest technical level within the guidelines of SNT-TC-1A (Recommended Practice for Personnel Qualification and Certification in Nondestructive Testing). This designation is designed for individuals who are not only proficient in the methods of NDT but also capable of developing and managing training programs, setting up procedures, and overseeing the technical aspects of NDT operations.

Level I technicians focus primarily on specific tasks under direct supervision and do not have the qualifications necessary to interpret results or conduct evaluations independently. Level II personnel are expected to have a more comprehensive understanding of the techniques and to interpret results, but they still operate under the supervision of a Level III. As such, Level III's qualifications encompass all the responsibilities and knowledge required for Levels I and II, along with additional expertise in management and development of NDT techniques.

Thus, it is accurate to assert that the qualifications of Level III are a higher tier than those of Level II, making the statement that Level III qualifications meet or exceed those of Level II correct. This hierarchical structure ensures that the highest level of expertise is maintained in NDT operations, guiding the entire organization in adhering to best practices and safety standards.
