The European Council stipulates transparency in the labor market. Especially non-formal and informal learning outcomes have to be formally recognized in a validation process. The majority of project partners have been dealing with the labor market and European transferable educational content in the field of "Event Technology" in two previous EU projects. By means of a “Competence Matrix” they managed to establish European comparability and transferability. In the labor market, there are many people entering the sector of “Event Technology” different from their educational or professional background. Although acting practically and solidly, they do not have any formal degree – with the resulting legal consequences, for example limited and restrictive insurance law and disciplinary consequences. This group of people is exemplarily fed to a validation process in all participating countries (DE, NL, UK, LI, AT ). A diagnostic tool will be developed and a way of formal recognition of the learning outcomes will be identified by investigating a small group of practitioners in each country using the diagnostic tool. The results will be presented to experts from institutions of formal recognition asking them under what circumstances they are willing to recognize this formally within their vocational training legislation. At the same time, the partners investigate in their national context to what extent these results are to be recognized transnationally. This can also lead to part recognitions. Based on the partner’s profound knowledge of the profession, the processes at the labor market and the framework of the formal examination institutions, satisfactory results will be elaborated. It will be investigated how to create confidence and appreciating the practicability of validation amongst formal certifiers by using a solid diagnostic tool. The project aims to demonstrate a method, which enables a mutual recognition of non-formal and informal learning outcomes. The project team assumes that the exemplarily investigated participants can obtain a formal (partial) recognition and that overall the process of validation continues in the among experts itself. Finally, an international project presentation will be prepared in order to present the results to the guests and representatives from Europe during a conference at the University of Bayreuth. A detailed work concept on behalf of the partners and a controlled reporting of the interim results will guarantee a targeted process of the partnerships. The publication of the diagnostic tool in relevant media and the further support by the coordinator BF/M-Bayreuth at the University of Bayreuth, together with long-term advice to stakeholders from other professional fields, will encourage the European Council’s recommendations and promote long-term validation.
