If the AHJ requires a professional engineering seal for a complex system, it is acceptable to submit a NICET IV stamp as an alternative.

• A. It depends on AHJ requirements
• B. PE seals and NICET stamps are equivalent
• C. NICET stamps are always acceptable
• D. Not allowed

Answer: (A)

Whether a NICET IV stamp can substitute for a professional engineer’s seal depends on the AHJ. For complex systems, the design often relies on the professional judgment and legal responsibility that a PE stamp provides, which is normally required by codes and authorities having jurisdiction. NICET IV shows technical competency, but it is not a licensed engineer’s seal. Some AHJs may accept NICET documentation in certain circumstances or with additional review, while others require a PE seal without exception. Because the acceptance depends on the specific AHJ’s rules and interpretations, the correct stance is that it depends on AHJ requirements.
