Self-paced, mobile-friendly, and designed for people who are working while they learn. No prerequisites unless the certification requires it.

Featured Track

Non-
Destructive
Testing.

NDT technicians inspect critical infrastructure — pipelines, bridges, aircraft, nuclear plants, offshore platforms — without cutting them open. It's high-stakes, high-skill, and high-demand work that keeps the world running.

Certified NDT techs are among the most sought-after technical workers in the country. Defense, energy, aerospace, and manufacturing can't function without them — and none of those industries are offshoring this work.

Average Annual Salary — NDT Technician (U.S.)
$65K — $120K+
Level III specialists in aerospace and nuclear routinely exceed $120K. Entry-level Level I positions start at $45–55K.

Real Workers.
Real Results.

I passed my ASNT Level II PT exam on the first try after completing the Gray Collar course. The material was clear, the practice questions were spot-on, and I got a $12K raise within three months.
Marcus T.
NDT Technician — Gulf Coast Oil & Gas
I was working in retail at 31 years old. Found NDT through the Gray Collar webinar, got certified in six months, and I'm now making more than I ever thought possible without a degree.
Jenna R.
Level I NDT Tech — Aerospace MRO, Florida
Coming out of the military, I needed credentials that employers would recognize fast. The NDT certification pathway at Gray Collar Academy was exactly that. Had three job offers before I even finished the course.
