ASNT Central Certification Program
The American Society for Nondestructive
Testing developed the ACCP (ASNT Central Certification Program)
for third party certification for NDT personnel in the United
States. This certification program is considered to exceed the
requirements of ISO 9712.
Certification is available for NDT
Level II and NDT Level III personnel in:
ACCP Level II personnel must complete
a “written instruction examination” in addition to
the General, Specific and Practical examinations used in most
other qualification examinations for certification.
ACCP Professional Level III certification
requires a “procedure preparation examination” in
addition to the Basic and Method Examinations required for an
ASNT NDT Level III certification. Additionally, a GHOP (Generic
Hands-On Practical) examination is a pre-requisite for ACCP Professional
Level III certification.
Certification is transportable and
valid for 5 years in all methods.
The USNRC has agreed to accept ACCP
certifications without further qualification examinations for
NDT personnel working at nuclear power plants.
