A first-rate navigation system is needed for initial and further vocational education and training (VET) to control the content, methods and organisation of VET services and to allow VET service providers to monitor and manage their own activities reliably. To assure European quality, the labour and education market also needs cross-border practice standards for quality development of VET service providers in correlation with the Common Quality Assurance Framework. Cross-border mobility of employees and transnational VET projects require comparable quality standards in initial and advanced VET. With this in mind, the aim of the pilot project is to develop QUALITY GUIDELINES for defining requirements for a transnational quality management system for VET organisations. These guidelines define minimum standards for content and determine methods of quality inspection (external audit and self-test). QUALITY GUIDELINES focus on processes as well as structures and results (VET on offer and VET services). The pilot project involved partners from EU countries with different quality assurance experiences. In the project, different quality experiences of the European partners (framework conditions, methods, standards) were compared and aggregated to an experience-oriented knowledge base in keeping with the Common Quality Assurance Framework. The requirements for a practice model were then described on the basis of this knowledge and the model was tested. Different levels are possible. The implementation was compared transnationally and examined scientifically. The aim of the work was to reach consensus about quality and to report on the analysed need for European regulation. An Internet-supported Competence Center was developed in addition to QUALITY GUIDELINES. This virtual quality workshop for transnational use enabled and further enables information exchange and also makes essential results accessible to other users of the working platform.
