The testing process is realised by all five partnership countries and spread over a period of three months. The test of the elaborated courses focus on the technical diagnosis connected with error detection and correction of structured didactic materials. Comments made by pilot testing participants including minor diagnosed programming flaws will shape the final version for the courses improvement. The aim of the testing process is to discover the opinion of the representatives of target users regarding the courses’ substantive content, practical usefulness in their jobs and desired level of skills which should be developed by completing the courses.
