NDT Questions and Answers

What is the NDT certification exam?

The Nondestructive Testing (NDT) certification exam validates a technician's ability to inspect materials and welds without causing damage using methods like ultrasonic, radiographic, magnetic particle, and liquid penetrant testing. It is governed by ASNT under standards SNT-TC-1A and CP-189, or by ACCP for central certification across multiple employers.

What format does the NDT Level II exam follow?

The NDT Level II exam includes three parts: a general written exam on the method's principles, a specific written exam on employer procedures and codes, and a hands-on practical exam requiring candidates to inspect test specimens, interpret indications, and write an inspection procedure. All three must be passed independently.

What is the passing score for the ASNT NDT exam?

Candidates must score at least 70 percent on each individual section (general, specific, and practical) and achieve a composite average of 80 percent across all three parts. Failing any single section requires retesting that portion, even if the composite score meets the minimum threshold.

What topics are covered on the NDT written exam?

The general exam covers physical principles, equipment, test procedures, safety, and standards for the chosen method such as UT, RT, MT, PT, ET, or VT. The specific exam covers employer codes, acceptance criteria, and written procedures including ASME Section V, AWS D1.1, and API 1104 requirements.

What are the eligibility requirements for NDT Level II certification?

Candidates need documented training hours that vary by method, typically 40 hours for Level II ultrasonic or radiographic testing, plus experience requirements of 400 to 1,200 hours depending on the method and prior education. A high school diploma or equivalent is required, along with a current vision test.

How do I register for the ASNT NDT certification exam?

Register directly through asnt.org by creating an account, selecting the certification program (ACCP or Central Certification Program), and submitting documentation of training hours, experience, and vision acuity. Exam fees range from approximately 285 to 485 dollars per method, with scheduling at approved Prometric or ASNT testing sites.

How long does the NDT Level II exam take to complete?

The general written exam allows 2 hours for 40 questions, the specific written exam allows 2 hours for 20 questions, and the practical exam typically takes 4 to 8 hours depending on the method and number of specimens. Total testing time often spans one to two days.

What are the best study tips for passing the NDT exam?

Review the ASNT Level II Study Guide for your specific method, memorize formulas for sound velocity, half-value layers, and attenuation, and practice interpreting radiographs or A-scan displays daily. Complete timed practice tests, study applicable code sections like ASME V Article 4, and log hands-on specimen inspection hours before test day.
