ITC Level II case studies
ITC Level II · Put your knowledge to work in context.
The ITC Level II Thermography Certification is a professional credential offered by the Infrared Training Center (ITC), an industry training provider, for thermographers who have moved past entry-level infrared inspection and want to work at an advanced analytical level. ITC lists it alongside a Level II Electrical track, which focuses the same advanced skill set on complex electrical inspection work. The training builds on Level I content and emphasizes infrared image analysis, inspection techniques, and the judgment needed to turn a thermal image into a defensible finding. Candidates reach it through ITC's course catalogue, which includes onsite classes and an online certification program delivered as a live virtual classroom where participants can interact with instructors and other thermographers in real time; certification follows successful completion of a final exam. The ITC Level II case studies are 5 cases and about 2,590 words.
