eLearning is available 24/7 so you can learn when and where you want so you can study around your current work hours and be mobile, as long as you have a device capable of doing so.

Another benefit is that you set the pace, spending as much time as you like on the parts you find challenging and speeding through those that you find easy. Study in short sessions, or work your way through the whole day. You can also track your progress as the eLearning platform will record all your work!

We have launched a range of blended learning non-destructive testing (NDT) courses, giving you more choice and opportunities for more flexible learning when you enrol.

The courses cover everything technicians need to know to be able to perform these widely used ultrasound-based methods of inspection.

We offer both certification (blended learning) and non-certification products (pre-course, refresher and appreciation courses) for ultrasonic testing (UT), phased array ultrasonic testing (PAUT), PAUT data analysis, time of flight diffraction (ToFD) and ToFD data analysis.
