ASNT NDT Level III Examinations

ASNT NDT Level III certification candidates are required to pass both the NDT Basic and a Method examination in order to receive the ASNT NDT Level III certificate.

A maximum of three examinations in any Method or the Basic examination is permitted within a two-year period.

Exam Specifications

The table below lists the number of questions and time allowed for each exam. Clicking on an exam will take you to an abbreviated topical outline and reference page for that exam. For the full topical outlines and complete list of references, see the topical outlines listed in the American National Standard ANSI/ASNT CP-105, Standard Topical Outlines for Qualification of Nondestructive Testing Personnel.
