NDT online courses are a great way to brush up on NDT methods and techniques while learning something new at the same time. Each course takes the learner through a series of "micro-learning" modules entailing video instruction, interactive activities, knowledge checks, and quizzes. Credit value per course: 1.5 contact hours; 0.5 recertification point. (The IACET CEU equivalent that may be awarded is 0.2.) Note: Your total time spent in each e-course is monitored and recorded by ASNT Learn administrators. If it is determined by the Certification Department that insufficient time was spent to be able to view all videos and complete all activities and quizzes, your certificate may be revoked. It is understood that your contact time may vary depending on your prior knowledge of the subject, reading speed, and other factors. The 1.5 contact hours is an estimated maximum time for completing the course.
