How do Level I and Level II responsibilities in VT differ according to common NDT standards?

• A. Level I performs VT inspections under direct supervision, carrying out basic observations and recording results.
• B. Level I performs VT inspections under direct supervision, carrying out basic observations and recording results; Level II interprets indications, develops/qualifies procedures, supervises Level I, and ensures compliance with standards.
• C. Level II performs inspections under direct supervision and records results.
• D. Level II handles only documentation and does not interpret indications.

Answer: (B)

Visual testing relies on a clear split of duties. A Level I technician conducts the inspections, makes basic observations, and records results under direct supervision. A Level II is qualified to interpret indications, develop and qualify procedures, supervise Level I personnel, and ensure compliance with the applicable standards. This combination—that Level I handles the hands-on inspection under supervision and Level II handles interpretation, procedure development/qualification, supervision, and standards compliance—is exactly what the best description conveys. The other options either limit Level II to basic or supervised inspection or reduce Level II to documentation only, which does not align with how responsibilities are defined in typical NDT standards.
