Lack of permeability - between sectors and levels - is one of the main challenges in vocational education and training (VET). Existing systems are mainly targeting a training perspective, whereas the industry itself requires relevant skills and competences in a flexible and changing business environment. The difference between applying learning objectives or learning outcomes when comparing is crucial to the understanding of how the individual's background and potential can be capitalised in employment.The objective of the project is to elaborate vertical transparency between EQF (European Qualifications Framework) levels 3-7, crossing sectoral borders and secure a reciprocity in the understanding and accreditation of aggregated skills and competences, independent of formal or nonformal ways of acquiring them. The basic concept will be the ECVET principles (European Credit system for Vocational Education and Training), underlining the description and accreditation of learning outcomes as the "currency exchange basis".The project builds on experiences gathered in the EU Leonardo projects VQTS and CREDIVOC, the German ANKOM project and the EU ECVET project SME Master, a transnational comparison of skills and competences required to obtain the certificate of a Master of Skilled Crafts (Brevet de Maîtrise - Meisterbrief - Mesterbrev). The consortium is based upon the cooperation between stakeholders like competent bodies, training and certification providers, higher education institutions, authorities and social partners as well as research and development organisations within VET. The consortium represents experience from more than 100 EU financed projects in different VET sectors.Building upon previous methods and experimental and/or implemented examples of reciprocal cooperation between higher education institutions and post secondary VET providers, the project will experiment new combinations where nationally or sectorally accredited certifications are valid when crossing previous barriers in systems. Crafts and crafts like vocations at post-secondary level will be selected (eg construction, electro(nics), car maintenance/repair or estethetics like floristry/hairdresser).With functioning systems of crossover certifications, the skills and competences of individuals and in the workforce in general opens for flexibility in how human resources can be optimised and where individuals can run through alternative careers and training paths - as expressed in the Norwegian White Paper 2008:18, VET for the future.The outcome of the project will be an ECVET based model where education and training providers and accrediting institutions can find a functioning tool for bridging over existing differences when training pathways are to be developed and accredited. For transnational mobility in training as well as for a mobile workforce, these are areas where the demands are often expressed - and where this type of solution should be most welcome.
