Final answer:
Eligibility for the ASNT NDT Level III exams requires a degree in a technical field and 3–5 years of related work experience, or 6–10 years of work experience with formal training. Applying math and science to problems and strong communication skills are also important.
Step-by-step explanation:
To be eligible to sit for the ASNT NDT Level III exams, a candidate with two years of passing grades in engineering or science study at a university or technical school must possess a degree in a technical field such as mechanical engineering, physics, chemistry, or polymer/materials science, combined with 3–5 years of related work experience. Alternatively, a candidate can qualify with 6–10 years of related work experience supplemented by formal technical training or certification. It is crucial for engineering students to be able to apply math and science to problems as well as use them as tools in their professional work. Candidates are also expected to have strong communication skills to initiate, establish, and maintain positive relationships both internally and externally.
