NDT instructors spend a lot of time answering questions. It is good for us to sit on the other side of the room once in a while.
This week, we are in Columbus, Ohio, for ASNT 2026, October 12–15. We are attending technical sessions, asking questions, and comparing notes with people doing inspection work across the industry.
We want to bring something useful back to the next person sitting in our classroom.
Working in inspection builds a collection of lessons you tend to remember. The difficult geometry. The unexpected indication. The job that took considerably more thought than the work order suggested.
But even an experienced inspector has only seen part of the picture.
Someone working in aerospace, power generation, or utility infrastructure may have spent years dealing with a problem you rarely encounter. Hearing how they approached it, what went wrong, and what they changed can give you something worth thinking about.
Sometimes a short conversation gives you a clearer way to explain a concept you have taught for years. Sometimes it leaves you with a question you need to investigate.
Both are good reasons to take notes.
New inspection equipment is a good reason to walk an exhibit floor. It is also a good reason to arrive curious.
What is this equipment designed to find? What are its limitations? What conditions affect the result? What does the operator need to understand before trusting the information on the screen?
Those questions belong in the classroom, too.
A student may be able to follow a setup sequence correctly. Ask them why each step matters, or what they would check if a result seemed wrong, and you learn much more about their understanding.
That is what we want to develop through NDT training at TXNDT: the ability to explain what you are doing, recognize limitations, and know when to stop and ask for help.
A technical presentation might suggest a better practical exercise. A discussion with another instructor might help us explain something students regularly struggle with. A field example might reveal a question our current lessons should address more clearly.
Those ideas still need to be evaluated. Before bringing something into a course, we should understand where it applies, what supports it, and how it fits the work our students will be doing.
The same responsibility applies to our Level III consulting. Employers depend on sound advice about procedures, training, and personnel qualification. Keeping our own knowledge current is part of doing that work well.
If you are considering NDT, pay attention to how experienced inspectors approach learning.
The people worth learning from can usually tell you about something that surprised them. They have questions of their own. They know when they need another opinion.
You do not need to know everything on your first day of class. You do need to ask questions, practice carefully, and take correction seriously.
We expect that same willingness to learn from ourselves.
This week, that means listening closely in Columbus and keeping a notebook open.
