As of March 12, 2026, ASNT's initial NDT Level III path requires a 135-question Basic exam plus at least one method exam. The Basic exam lasts 4 hours; method exams last 2 hours for IR, MFL, MT, PT, and VT, or 4 hours for AE, ET, LT, RT, and UT. ASNT lists a $325 application fee, a $535/$615 Basic exam fee, and method exam fees ranging from $515-$535 for members or $595-$615 for nonmembers depending on method length. ASNT does not publish a public passing-score percentage or official domain weighting chart, so this bank maps the public Basic-exam task outline rather than inventing an official weight table.

Frequently Asked Questions
Is ASNT NDT Level III one exam or multiple exams?
It is a certification path, not a single fixed test form. For initial certification, ASNT requires the 135-question Basic exam plus at least one method exam. That is why the total number of official exam questions and total testing time vary by the method you pursue.
How many questions are on the ASNT NDT Level III exams?
The Basic exam has 135 items and a 4-hour time limit. Method exams have either 90 items in 2 hours for IR, MFL, MT, PT, and VT, or 135 items in 4 hours for AE, ET, LT, RT, and UT. ASNT also notes that exam forms include some pretest questions that are not counted in scoring.
What passing score do I need for ASNT NDT Level III?
ASNT does not publish a single official passing-score percentage for the Level III exams. On its psychometrics page, ASNT says its exam cut scores are typically in the 70% to 80% range and are set using accepted psychometric methods such as Angoff or IRT. The safest strategy is to study for broad mastery rather than target an unofficial rumor.
How much does ASNT NDT Level III cost in 2026?
ASNT's published 2026 pricing lists a $325 application fee, a $535 Basic exam fee for members or $615 for nonmembers, and first-attempt method exam fees ranging from $515 to $535 for members or $595 to $615 for nonmembers depending on the method. For one Basic exam plus one first method exam, that puts the total initial path at roughly $1,375 to $1,555 before study materials or travel.
What experience is required before I can apply?
ASNT scales eligibility by education. The public ASNT table says a high school diploma or equivalent requires 12 years of work experience, while a bachelor's degree in a related field can reduce that to 4 years. Candidates must document qualifying experience as part of the application process before they can schedule their exams.
What changed for ASNT NDT Level III in 2026?
ASNT's public examination page identifies three exam-relevant 2026 changes. For Basic exam self-study materials, the recommended references changed on January 1, 2026 from the 2020 editions of SNT-TC-1A and CP-189 to the 2024 editions. ASNT also published updated Ultrasonic Testing topic coverage for exams after July 2026 and updated Radiographic Testing topic coverage for exams after August 18, 2026.
Why does this practice bank focus on the Basic exam outline?
Because the Basic exam is the only exam section every ASNT NDT Level III candidate must take, regardless of method. ASNT publishes the Basic exam's domain outline publicly, but it does not publish a public percentage-weighting chart for each Level III subject area. Focusing the bank on the Basic outline gives all candidates a common, official foundation before method-specific study.
