Questions
What is the NIHST competency standard?+
It is the written, versioned set of competencies a hazardous-location finishing technician must demonstrate to earn a NIHST credential. It is the substance the certification measures, and the basis a state can later codify into licensure.
Why is the standard versioned?+
Each credential is tied to the standard version it was earned against, so the record is precise as codes and equipment evolve. Recertification brings a technician up to the current version.
Who authors the standard?+
An expert panel anchored by Benjamin Kurtz, whose factory certifications and field experience establish the program's psychometric and technical credibility.
