A requirement for the completion of the Arts4All e-learning platform was the piloting with the target group (young people) in all partner countries. During these test runs, it was checked whether all language versions were complete and comprehensible, whether all functions and links of the platform worked properly and, of course, whether the young people liked the platform (choice of topics, exercises and the layout). In a questionnaire, the participants gave feedback on these topics, which was evaluated by the partners. Overall, the participants were very satisfied with the e-learning platform and there were only minor suggestions for improvement and indications of malfunctions, which were then taken into account in the final optimisation of the platform. A total of 4 piloting sessions took place in the partner countries with a total of 59 participants. The e-learning platform is the basis for the mobile application of the three Arts4All modules on smartphones.
