After training for each member we create a profile page and a digital testimonial document that can be printed. This testimonial can be used for a job interview as complement to your college degree. Some engineers appreciate self study and on-line courses you have taken.

Disclaimer: These testimonial do not represent a degree, qualification or diploma. It is merely an open letter of recommendation. You can use it to prove you have completed our training program.  


Before you can order a testimonial document you must follow required classes and pass the ratting exams. Chose your learning path to qualify for a title that will be used on your profile page.
