What is emphasized for Level III personnel during examinations in terms of content retention?

The emphasis for Level III personnel during examinations is rooted in the expectation that they not only have a broad knowledge of non-destructive testing (NDT) principles, codes, and standards, but also possess the ability to effectively reference materials during tests. This capability is vital because the field of NDT encompasses a myriad of procedures, specifications, and standards that a Level III professional is expected to understand and apply in practice.

Understanding underlying principles allow personnel to successfully navigate the complex scenarios they might encounter. Solely relying on memorization of material can be limiting, as it may not account for the nuanced application of principles related to codes and procedures. Hence, while some degrees of retention is necessary, the focus is on the ability to utilize references effectively. This reflects a well-rounded approach that values both foundational knowledge and the practical ability to apply that knowledge in a real-world context.
