If you’ve found a job that you love, you want to be your best.

Once you’ve settled into the right vocation, settling for the status quo is no longer sufficient and you’re likely to find yourself longing for improvement, wanting to stretch yourself further.

In the nondestructive testing field-- as in most fields-- there are a number of levels technicians can be certified in, each representing a different amount of skill and experience.

With all of these different levels of certification available to NDT technicians, is there any level that is better than another? Is the highest level of certification required to enter into the NDT field?

Here’s what you need to know.

Levels of Certification

The different levels of NDT certification represent more than just hours of experience. With each level, there are different expectations for what a technician is able to accomplish and how much autonomy they are given on a job.

At TXNDT, we offer certification at a variety of levels, demonstrating introductory skills to high proficiency.

  • Level I Limited and Level I: the lowest level of NDT certification, which involves learning the basics on nondestructive testing and conducting tests under close supervision
  • Level II: at this level, technicians have more experience, are familiar with how to prepare for and conduct various nondestructive tests, and can supervise less experienced technicians
  • NDT Level III Certification: Technicians at this level are highly skilled and serve as supervisors and instructors as well as experienced technicians.

Working Independently

To be an NDT technician working in the field, level 3 NDT certification is not necessarily a requirement, but having the highest level of certification does increase the likelihood that a technician will have the skills and experience required to complete any job presented to them.

In the case of freelance technicians who work on a contract basis, you would be hard-pressed to find a company likely to enlist the services of a technician who only has a level 1 limited certification.

Lower levels of certification require supervision that many companies do not wish to, or are unable to, provide, so the chances are that a company is more likely to commission the work of a technician with level 3 certification because their certification implies that they can work independently.


Aside from a level 3 certified NDT technician’s ability to work without close supervision, those with the highest level of certification are also required to have familiarity with a greater number of testing methods and approaches.

Since the nondestructive testing field is so vast, the skills needed for each job will vary drastically from project to project.

By reaching level 3 certification, clients looking to enlist your services can rest assured that you will be prepared to approach anything required of you-- and do so with skill.
