ASNT's VT Level III is a 90-question, 2-hour Pearson VUE method exam with a 70% passing score. Candidates must pass it together with the ASNT Level III Basic exam. The VT outline covers optics and vision, lighting, direct and remote VT tools, weld terms and discontinuities, AWS D1.1/ASME/API acceptance criteria, and procedure/documentation per SNT-TC-1A and CP-189.
Sample ASNT VT Level III Practice Questions
Try these sample questions to test your ASNT VT Level III exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.
1Per ASME Section V Article 9, what is the minimum near-vision standard a visual testing examiner must demonstrate on a standard Jaeger chart?
2How often must the near-vision examination be administered for certified VT personnel under typical NDT written practices?
3Which part of the human eye is most directly responsible for fine-detail near-vision acuity used during VT?
4Why is color perception evaluated as part of VT personnel qualification?
5Parallax error during direct VT measurement is best minimized by which examiner action?
6Depth perception in direct VT is primarily provided by which mechanism?
7An examiner needs to read a Jaeger J1 line that subtends roughly 0.07 in. of letter height. Which factor most directly limits whether the examiner can resolve those letters?
8Why is contrast between an indication and its background a critical factor in detecting fine surface flaws during VT?
9Per ASME Section V Article 9, the eye-to-surface distance for direct VT should generally not exceed which value?
10Per ASME Section V Article 9, the minimum angle of view from the surface for direct VT is:
About the ASNT VT Level III Exam
The ASNT NDT Level III Visual Testing (VT) method exam tests Level III-grade knowledge of optics and vision, lighting, direct and remote visual testing tools, weld terminology and discontinuities, acceptance criteria across AWS D1.1, ASME Section V Article 9, ASME Section VIII U-1, and API 1104, and VT procedure and documentation per SNT-TC-1A and CP-189. This 100-question bank maps to the public CP-105 VT topical outline used by ASNT to build the actual 90-question VT method exam.

ASNT VT Level III Exam Content Outline
Optics & Vision
Eye anatomy, near-vision acuity (Jaeger J1/J2), color perception, depth perception, parallax, and how human vision limits detection.
Lighting
100 fc (1000 lx) ASME minimum, color rendering index (CRI), glare control, contrast, and verification of light intensity at the surface.
Direct VT Tools
Magnifying glasses, optical comparators, fillet weld gauges, undercut gauges, V-WAC, HI-LO, bridge cam gauges, and other weld inspection gauges.
Remote VT
Rigid borescopes, fiberscopes, videoscopes, robotic crawlers, and drones for confined, hot, or hazardous-access inspections.
Weld Inspection
Weld terms (root, crown, toe, fillet, groove) and surface discontinuities (undercut, overlap, porosity, lack of fusion, crater cracks, arc strikes).
Acceptance Criteria
AWS D1.1 visual acceptance, ASME Section VIII U-1, ASME Section V Article 9, and API 1104 visual rules with limits and accumulation.
Procedure & Documentation
Qualification per ANSI/ASNT CP-189 and SNT-TC-1A, written VT procedures, annual vision exams, and inspection records.

Frequently Asked Questions
How many questions are on the ASNT NDT Level III VT exam?
ASNT's VT method exam has 90 multiple-choice questions and a 2-hour time limit. Some items may be unscored pretest questions used by ASNT to build future forms.
What is the passing score for ASNT VT Level III?
ASNT's published guidance places Level III cut scores in the 70% to 80% range, with 70% being the most commonly cited working target for VT method preparation.
Where do I take the ASNT VT Level III exam?
ASNT delivers VT Level III through Pearson VUE testing centers and approved authorized exam centers. You can schedule once ASNT approves your application.
What lighting and vision rules show up on the VT exam?
Expect ASME Section V Article 9 rules: a minimum of 100 fc (1000 lx) at the surface for direct VT, and annual near-vision exams demonstrating ability to read Jaeger J1 or equivalent letters with one or both eyes (corrected or uncorrected).
Which codes are tested for VT acceptance criteria?
The VT outline most often references AWS D1.1 (structural steel welding), ASME Section VIII U-1 (pressure vessels), ASME Section V Article 9 (visual NDE methodology), and API 1104 (pipeline welding).
Do I have to pass the ASNT Basic exam as well?
Yes. Initial ASNT NDT Level III certification requires passing the 135-question Basic exam plus at least one method exam. For VT candidates, the method exam is the 90-question, 2-hour VT exam.
How is direct VT different from remote VT?
Direct VT is performed within arm's length of the surface, typically less than 24 inches at an angle not less than 30 degrees, using the unaided eye plus aids like magnifiers and gauges. Remote VT uses borescopes, fiberscopes, videoscopes, robotic crawlers, or drones to inspect surfaces the inspector cannot reach directly.
