ASNT Certification

ASNT Certification is the most recognized credential for NDT

For nearly half a century, ASNT certification has been the standard for the nondestructive testing industry. ASNT is accredited as a third-party certification body by the American National Standards Institute (ANSI). ASNT’s certification process has improved the quality of the profession, and provided an accepted means for members to demonstrate they have met the requirements of the industry. 

For employers, ASNT certification is an impartial validation of the competence of NDT personnel in the field.

There are four ASNT certification programs: 

The ASNT NDT Level III Program and the Industrial Radiography and Radiation Safety Personnel (IRRSP) program are accredited by ANSI to ISO/IEC 17024:2003, Conformity assessment – General requirements for bodies operating certification of persons.
