2.1 Training Hours, Experience Days, and Documentation

Passing the American Society for Nondestructive Testing (ASNT) Nondestructive Testing (NDT) Level II computer-based exams starts with an approved application. ASNT Certification Services will not issue a Letter of Approval—and you cannot schedule Pearson VUE or authorized-center appointments—until training and experience are documented to the published day counts for the method you want. This section is the administrative gate that keeps qualified technicians in the pipeline and sends incomplete files back for another review cycle.

Why Training and Experience Documentation Matters

ASNT NDT Level II is a central certification. Unlike a purely employer-issued wallet card created only under a shop procedure, the national application is reviewed against published tables. Candidates who confuse a weekend seminar with method experience, or who upload a Level I wallet card as proof of Level II duties, burn the typical 2–4 week application-review window and delay testing. The written exams themselves—a 50-question general plus a 40-question specific—do not ask you to invent a private employer's hour matrix, but they do assume you know how certification systems document qualification. If you later sit ultrasonic testing (UT) topics on training and certification, the same vocabulary appears.

Treat the application as a technical procedure: the right records, signed by the right person, stating the right facts, in English.

How ASNT Defines a Day

ASNT publishes eligibility in days, not as a separate official hour table on the Level II certification page.

One day means at least seven hours. Those seven hours can be accumulated. Four hours on a Saturday plus three hours the next evening is one day. ASNT does not publish a fractional-day formula on the Level II page, so do not convert a ten-hour shift into 1.4 days on the application. Count complete seven-hour days and keep leftover hours until they add up to another day.

This definition applies to both training and experience. It matches the way Recommended Practice No. SNT-TC-1A, Personnel Qualification and Certification in Nondestructive Testing, talks about work experience. ASNT's Level II page points to that recommended-practice definition: work experience must be:

• in nondestructive testing
• gained while under the direction of qualified supervision
• in the test methods you are applying for

Time spent painting, welding, fitting, or running a machine shop—even in a facility that also does NDT—does not become NDT experience until you are actually performing NDT under qualified supervision in the method on the application.

ASNT-Published Day Requirements by Method

ASNT currently offers NDT Level II central certification in five methods: magnetic particle testing (MT), liquid penetrant testing (PT), radiographic testing (RT), ultrasonic testing (UT), and visual testing (VT). Do not assume eddy current, acoustic emission, leak testing, neutron radiography, or infrared have an ASNT NDT Level II path on this program.

Read the three columns as separate gates. For UT you need 12 days of training, 120 days of UT experience, and 229 days of total NDT experience. The 120 UT days can count toward the 229 total, but 229 days of PT and MT with almost no UT will not satisfy the method-experience column. Surface methods (PT, MT, VT) have shorter tables; volumetric methods (RT, UT) require four times the method experience (120 versus 30) and six times the PT classroom days (12 versus 2).

You enter these figures in MyCert, the online application platform tied to your MyASNT account. Have the supporting files ready before you start. Payment must also be received in full before ASNT will review the file—documentation and fees travel together.

How SNT-TC-1A Recommended Hours Relate — Without Replacing ASNT Days

Employer written practices usually quote SNT-TC-1A recommended hours, not ASNT days. The 2024 recommended-practice hour set that the ASNT day counts implement is:

Use this table to translate an employer's hour log into the language of ASNT days. Do not replace the ASNT day counts on the application. If a procedure says "80 hours UT Level II training," that is the SNT-TC-1A recommended-hour counterpart of ASNT's 12 training days. You still document 12 days of training for the ASNT file, using ASNT's seven-hour day.

A common failure mode is the opposite error: a candidate with 40 hours of mixed "NDT overview" classroom time claims 40 days of UT experience. Hours of a survey course are training, not days of method experience.

What Counts as Qualifying Experience

Qualifying experience is NDT work, not adjacent industrial time. It must be performed under qualified supervision—typically a Level II or Level III designated in the employer's written practice—and it must be in the method named on the application.

Examples that usually count when the record is signed, dated, and specific:

• Performing MT yoke inspections of welds and recording results under a designated Level II
• Processing PT parts, evaluating indications, and completing reports
• Setting up UT calibrations and scanning welds or plate under supervision
• Interpreting radiographs or performing VT of in-service equipment to a written procedure

Examples that do not convert into method experience by themselves:

• Completing a 40-hour classroom course (document that as training)
• Holding only a Level I certificate
• Self-study, unpaid practice on scrap, or watching demonstrations with no supervisor
• Quality-manager time that never included performing or directly supervising the method

Experience Documentation ASNT Will Accept

Acceptable experience documentation must be signed by the employer (or must meet the self-employed rule below). ASNT lists:

• inspection logbooks
• inspection reports
• employer or third-party certificates or certification records
• human resources (HR) records
• a signed statement from your employer or responsible Level III
• a signed statement from an ASNT NDT, ASNT Central Certification Program (ACCP), or 9712 Level III professional

9712 here means a Level III certified under ISO 9712, the international NDT personnel-qualification standard. An ACCP or ISO 9712 Level III signature is accepted in the same list as an ASNT NDT Level III signature.

The file must state:

• the level of qualification, or
• Level II job duties, and
• the number of days working at Level II or comparable responsibilities

A letter that says only "Jordan is a reliable technician" without a level, a duty description, or a day count is not a qualifying record.

Self-employed applicants cannot sign their own experience. Provide signed statements from at least two customers. One long-term client is not enough, even if that client provided most of your billable days.

All documentation must be in English or accompanied by an English translation.

Training Documentation ASNT Will Accept

Training is documented separately from experience. Acceptable items include:

• copies of training certificates
• a letter of completion
• employer or third-party certificates or certification records
• a signed statement of completion from the trainer or a training-company executive
• a signed statement of completed training hours from an ASNT NDT, ACCP, or 9712 Level III

Classroom hours, structured laboratory time, and formal employer courses belong here. Do not reuse a training certificate as if it were an experience log. The same piece of paper cannot fill both columns unless it is actually two different attestations.

Documents That Are Not Accepted as Experience

ASNT is explicit about three rejections:

• certificates of training (wrong document type for the experience column)
• non-employer-issued qualifications (a course provider cannot attest to your job duties or day counts)
• Level I certificates (they do not prove Level II or comparable responsibilities, and they do not state Level II day counts)

If your only uploads are a 40-hour MT class certificate and a Level I wallet card, the experience column is empty even if you have been in the shop for years. Go get a signed employer or Level III statement that states duties and days.

Realistic Application Scenarios

Scenario 1 — Accumulated days. A refinery helper works PT two evenings a week for three hours. After ten such evenings the helper has 30 hours. Under the seven-hour rule that is four days with two hours left over (30 ÷ 7 = 4 full days, remainder 2 hours). The leftover hours carry forward; they do not round up to a fifth day. PT Level II still needs 30 method days and 58 total NDT days, so this helper is early on the experience clock.

Scenario 2 — Method mismatch. A technician documents 229 days of combined MT and PT and 12 days of UT classroom training, but only 20 days of actual UT scanning. The UT training column is met; the 120-day UT method column is not. The UT Level II application is incomplete until the method-experience gap closes.

Scenario 3 — Self-employed inspector. An independent VT contractor uploads one customer letter covering 80 days of tank and structural visual work. ASNT requires at least two customer statements. Add a second signed customer letter that states Level II-comparable duties and the number of days.

Scenario 4 — Wrong artifact. A candidate scans a PT training certificate into the experience upload slot because the filename says "cert." Training certificates are accepted for training, not for experience. Upload logbooks, reports, HR records, or a signed employer / Level III statement for the experience column.

Build the file the way you would build an inspection package: complete, signed, in English, and matched to the published day table for the method you will test.
