What specific experience should a Level II candidate have before being elevated to Level III?

A Level II candidate should have a minimum of 2 years of supervised experience before being elevated to Level III. This requirement is based on the necessity for practical knowledge and hands-on skills in non-destructive testing (NDT) methods. During this two-year period, a candidate will gain exposure to a variety of techniques and specific applications of their testing methods under the guidance of more experienced personnel, which is crucial for the advanced responsibilities expected of a Level III.

Moving up to Level III entails not only a deeper understanding of the principles and practices in NDT but also the ability to oversee and manage testing procedures, interpret results, and ensure compliance with industry standards. The supervisory experience gained during this time is vital to prepare candidates for the complexities and decision-making responsibilities that come with the Level III certification.

The other options do not capture the essential experience required for Level III. While passing a comprehensive exam is an important aspect of assessing knowledge, it does not replace the need for practical, supervised experience. Graduation from a technical college, while beneficial, does not necessarily equate to the hands-on experience needed in the field. Extensive field training alone, without the supervision element, may not provide the depth of knowledge required to meet Level III responsibilities effectively.
