The American Advanced Technical Academy (AATA) is a Los Angeles-based 501c3 nonprofit. AATA's mission is to bring high quality basic and advanced NDT training to the industry at a price that is affordable; so everyone especially veterans, women, minorities and disenfranchised individuals can take advantage of the great professional opportunities offered in Non-Destructive Testing (NDT).

AATA students receive Level I and Level II training in Radiography, Magnetic Particle, Penetrant, Ultrasonic Testing, UT Phased Array and Visual Testing, in addition to training in Computed Radiography and Radiation Safety with a foundation in NDT Math.

The AATA was founded when John Stewart decided to dedicate himself full-time to helping economically disadvantaged people and veterans struggling with poor job prospects secure fulfilling careers in his field. Stewart, who over the course of his twenty-year career in NDT has trained technicians for companies such as SpaceX, Goodrich Aerospace and Northrop Grumman, believes that by addressing inadequate STEM opportunities, one could empower youth and returning military veterans to fill the shortage of NDT professionals nationwide.
