ASNT NDT Level III certification: exams, eligibility, fees and renewal

This guide covers ASNT NDT Level III. ASNT 9712 Level III is a separate program with its own page.

The exam route: Basic plus a Method

First-time applicants must pass two kinds of exam:

• NDT Basic. Required once, for your first Level III certification. ASNT's recommended references for Basic exams taken after 1 January 2026 are the 2024 editions of SNT-TC-1A and CP-189, which replaced the 2020 editions.
• At least one Method exam. ASNT offers Method exams in acoustic emission (AE), electromagnetic (ET), infrared and thermal (IR), leak (LT), magnetic flux leakage (MFL), magnetic particle (MT), liquid penetrant (PT), radiographic (RT), ultrasonic (UT) and visual (VT) testing. Each method you pass is its own Level III certification.

The exams are multiple choice and computer based, taken in person at Pearson VUE centers or ASNT's authorized exam centers. ASNT requires no practical exam for Level III, and all exams are in English. The ASNT NDT Level III exam page lists the item count, time limit and topic outline for each exam.

Once ASNT approves your application, you must schedule and complete every exam you applied for within one year of the approval letter. Change or cancel an appointment at least 48 hours ahead, or you lose the exam fee.

Eligibility: experience by education

ASNT sets the work experience you need by your education:

A day is at least seven hours, worked in one day or added up. Following the definition in SNT-TC-1A, the experience must be in NDT, under qualified supervision and in the methods you apply for.

You prove it with signed documents showing your Level II (or equivalent) experience for each method: inspection logbooks, inspection reports, employer or third-party certification records, or HR records, signed by the employer. They must state your level of qualification or your Level II duties, and the number of days you worked at Level II or comparable responsibility. If you are self-employed, send signed statements from at least two customers. ASNT does not accept training certificates, qualifications not issued by an employer, or Level I certificates.

ASNT NDT Level III fees

From the ASNT NDT Level III page, read 7 November 2026. You pay every fee in full when you apply.

A first certification in UT, for example, is Basic plus the UT exam: $1,090 for members or $1,250 for non-members. In MT or PT it is $1,070 or $1,230.

If you fail, you can retake after 30 days the first time, after 90 days the second time, and after one year the third time with a new application. ASNT allows no more than three attempts at any exam in two years.

Renewal every five years

ASNT NDT Level III certifications must be renewed every five years. You can apply up to six months before the expiry date, and ASNT asks for the application and payment at least 60 days before it. There are two ways:

• By points. Collect at least 25 points over the 60-month certification period, and work in Level III functions for at least 36 months (756 days) per method in that period. The fee for one method is $440 for members and $520 for non-members, rising with each added method.
• By exam. Retake and pass the Method exam for each method you hold, before your certification expires. You do not retake Basic while you hold a valid ASNT NDT Level III certificate. The fees match the initial Method exam fees above.

If you hold several methods, you can equalize them so they all renew on one date.

NDT Level II vs Level III

A Level II sets up, runs and interprets an examination to a written procedure. A Level III writes and approves that procedure, qualifies the people who use it and answers for results across jobs, as NDT Level 1 vs 2 vs 3 explains.

How to get ASNT NDT Level III certification

1. Find your experience row. Match your education to the table above and count your Level II (or equivalent) days in each method you want.
2. Gather your documents. Collect signed experience records for each method, and transcripts or a diploma if you use college to qualify. Anything not in English needs an English translation.
3. Apply in MyCert and pay. Create or update your MyASNT account, complete the online application, sign the ASNT Code of Ethics and Confirmation Statement, and pay all fees. ASNT says to allow 2 to 4 weeks for review.
4. Schedule your exams. After the approval letter arrives by email, schedule Basic and your Method exams through MyCert and finish them within one year.
5. Pass and keep it current. ASNT updates your MyASNT record and emails a digital badge. Track your points and Level III work for renewal in five years.
