Which parts of the Level I and Level II examinations are required to be written?

The requirement for written parts of the Level I and Level II examinations includes both the General Examination and the Specific Examination. The General Examination assesses the candidate's fundamental knowledge of non-destructive testing (NDT) principles, while the Specific Examination evaluates the candidate's understanding of the specific NDT method they are being certified in, along with relevant techniques and procedures.

These examinations are designed to ensure that candidates not only have a theoretical understanding of the principles involved in NDT but also a detailed knowledge of how these principles apply to specific testing methods. Both written examinations are crucial for establishing a candidate's competency before they proceed to practical applications in the field.

Practical evaluations, on the other hand, are not written tests; they focus on hands-on skills and the application of knowledge rather than theoretical understanding. The written component is essential, as it verifies the theoretical knowledge that supports practical skills in non-destructive testing.
