This eLearning training is part of the ‘blended learning’ Penetrant Testing; a mix of eLearning and in-class practical training followed by certification to EN ISO 9712. The online modules can be studied when and where it is most convenient and at your own pace.

The package separates the learning of theoretical concepts from the practical application of the method, coupled with questionnaires focused on the theoretical principles and specific applications related to different product and industrial sectors. 

In addition to the eLearning element of the Penetrant Testing, students will then attend practical classroom training for 2 days followed by certification exam in one of TWI Training facilities. 

Note for candidates wishing to enrol on the PT blended learning course:  
The e-learning modules require time to study. All students needs to plan their study time and complete the online modules (including all assessments) before joining the classroom. It is a mandatory requirement to issue access to the online material no less than 15 calendar days prior to the commencement of the in-class element of the course. There shall be no exception to this requirement, please plan your study to embrace this requirement. 

The Penetrant Testing Level 2 eLearning training courses consists of two main modules, to be completed in the order below: 

  • Module 1: Product Technology 
  • Module 2: Penetrant Testing Theory 

Each module contains: 

  • Downloadable course notes
  • Pages explaining the underlying theory 
  • Self–assessment questionnaires   
  • A coursework section with questions on general and specific theory  
  • A personal tutor assigned to each certification candidate

At the end of your online training phase, by completing the coursework section you will automatically receive your results, which will indicate whether you are ready for the classroom element of the course, or if you need further time to study. 

When you have booked your online trainingyou will receive an email notification with your login details.  

You will then have 30 days from first login to complete your eLearning course or until the examination date. If there is more than 30 days between the completion of the online element and the classroom attendance, the material you have studied prior to attending the course will become available again for a further period of 15 days and remain available until the certification examination so that you can get yourself ready before coming to one of our training centres.
