Credential: ASNT NDT Level III Certification - Neutron Radiographic Testing (NR)  ANSI resource
Credentialing Agency: American Society for Nondestructive Testing (ASNT)

The ASNT NDT Level III program provides third-party certification for nondestructive testing (NDT) personnel whose specific jobs require knowledge of the technical principles underlying the nondestructive tests they perform, witness, monitor or evaluate. Neutron radiography (NR) uses an intense beam of low energy neutrons as a penetrating medium rather than the gamma- or x-radiation used in conventional radiography. Generated by linear accelerators, betatrons and other sources, neutrons penetrate most metallic materials, rendering them transparent, but are attenuated by most organic materials (including water, due to its high hydrogen content) which allows those materials to be seen within the component being inspected. When used with conventional radiography, both the structural and internal components of a test piece can be viewed. Candidates must have a minimum of 4 years of experience in an assignment at least comparable to that of a Level II in Neutron Radiographic Testing. 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.

More information can be found on the certifying agency's website.

Related As

The military occupations shown in this table are related to this credential in one of four ways: Most, Some, or Other.

Most: This credential is directly related to most of the major duties associated with the military occupation (at least 80%). Note that the credential may require additional education, training or experience before you are eligible for it.

Some: This credential is related to some tasks associated with the duties of the military occupation (related 80% to at least one or more critical tasks but less than 80% of all of the entire military occupation). Note that the credential may require additional education, training or experience before you are eligible for it.

Other: This credential is related to this military occupation, but is more advanced or specialized and therefore will likely require additional education, training, or experience.

Skill Level Designation

Skill Level I: This skill level consists of all Soldiers in the ranks of Private (pay grade E-1) up to Specialist (pay grade E-4). Time in Service (TIS) is generally between initial entry and four Years of Service (YOS). This skill level is Entry-level positions requiring performance of tasks under direct supervision.

Institutional training:

Skill Level II: This skill level is obtained when promoted to Sergeant (paygrade E-5). TIS is generally between 4-8 YOS. Positions requiring performance of more difficult tasks under general supervision; and in some instances, involving supervision of Soldiers in SL1.

Institutional training:

  • Structured Self-Development (SSD) level II
  • Advance Leader Course (ALC)

Skill Level III: This skill level is obtained when promoted to Staff Sergeant (paygrade E-6). TIS is generally between 8-12 YOS. Positions requiring performance of still more difficult tasks and involving first line supervision of Soldiers in SL1 & SL2.

  • Structured Self-Development (SSD) level III

Skill level IV: This skill level is obtained when promoted to the rank of Sergeant First Class (paygrade E-7). TIS is generally between 12-18 YOS. Positions requiring relatively detailed knowledge of all tasks specified for a given MOS, normally involving first-line supervision of Soldiers in SLs 1, 2, and 3, and involving managerial duties.

Institutional training:

  • Master Leader Course (MLC)
  • Structured Self-Development (SSD) level IV
  • Senior Enlisted Joint Professional Military Education (SEJPME) I Course

Skill level V: This skill level is obtained when promoted to the rank of Master Sergeant (paygrade E-8). TIS is generally between 18-22 YOS. Positions requiring direct and indirect leadership roles with expertise in company and battalion-level operations and competency across a given CMF, serving as members of a staff at every level in the Army, with a full understanding of the allocation of resources and their utilization in order to accomplish Army functions and missions.

Institutional training:

  • United States Army Sergeants Major Academy (USASMA)
  • Structured Self-Development (SSD) level V

Skill level VI: This skill level is obtained when promoted to the rank of Sergeants Major (paygrade E-9). TIS is generally between 22-30 YOS. Positions requiring organizational leadership roles with multi-dimensional expertise in units and teams on division, corps, and Army staffs, integrated with Joint, Interagency, Intergovernmental, and Multinational (JIIM) partners with a full understanding of the Force Generation process, operations at all echelons, and how the Army runs.

Star Credential Star icon

Star credentials are MOS enhancing, as designated by the Proponent. MOS enhancing credentials are directly related to an MOS or ASI, are taught either partially or completely as part of a Program of Instruction (POI), and improve the MOS technical proficiency.

Proponent Funded Funded icon

This icon indicates credentials which Soldiers may have funded through their MOS proponent. Some proponents offer credentialing opportunities in conjunction with military training and/or as part of MOS development beyond the training base.

ASNT NDT Level III Certification - Neutron Radiographic Testing (NR)

Renewal Period: 5 years

The ASNT NDT Level III Certification - Neutron Radiographic Testing (NR) credential has the following recertification information:

  • The ASNT NDT Level III program permits ASNT Level III certificate holders to renew by "Points" at 5-year intervals. The "points" system requires that certificate holders earn 25 points during their current 5-year certification period for NDT-related activities. See the point categories and structure.
  • Personnel that cannot document 25 points during their current certification period may renew by retaking the initial method examination for each method in which certified but must do so before their current certificates expire. 

    Personnel recertifying by examination need not retake the Basic examination as long as the applicant holds one currently valid ASNT NDT Level III certificate at the time of examination and passes that examination.
