The magnetic particle testing course is a twenty (20) hour class, consisting of classroom instruction, hands-on training session and a three-part final examination. This course is offered as an in-house program only. An in-house program is when a company hires ITAC to come to their facility and train a group of its employees. ITAC does not offer this class on a scheduled basis for individual attendance. Course outline appears on the following page.
