NDT Personnel Qualification & Certification
Requirements are based on a combination of training, examination, and experience. Training is based on an accumulation of training course outlines from the NDT Body of Knowledge document. More detail on the ASNT NDT Body of Knowledge can be found in the ANSI/ASNT American National Standard CP-105.
The purpose of the Body of Knowledge is to describe the knowledge and skills needed for different levels of certification. Several types of examinations are also necessary to meet minimum requirements and to re-certify. Individuals may have to take a written exam, specific exam, or a practical exam depending on the certification desired. Experience in NDT or NDT-related fields ,as well as on-the-job training programs, are also considered for certification.
