ASNT Preparatory/Refresher


We can help you prepare for an NDT exam, advance your career, increase your knowledge and much more. We provide several prep courses to help you continue learning and reach that next level.

The subject matter for all of courses is derived from the training topics found in CP-105, Recommended Practice No. SNT-TC-1A and CP-189.


ASNT refresher courses are considered Level III courses and are designed for those who are currently Level II or III and are looking to become an ASNT Level III or to maintain their Level III status.

The courses are structured around the same Body of Knowledge as the ASNT NDT Level III examinations.


All ASNT Preparatory/Refresher courses are taught by ASNT Level III Trainers.
