"The European Council in its informal meeting in January 2012 agreed that Member States should increase ""substantially the number of apprenticeships and traineeships to ensure that they represent real opportunities for young people, in cooperation with social partners and where possible integrated into education programmes"". In addition, according to the newly adopted ""European Framework for Quality and Effective Apprenticeships"" (October 2017), European Commission identifies 14 key criteria that Member States and stakeholders should use to develop quality and effective apprenticeships. Among the specific criteria, is made a concrete reference on the necessity to exist a specific procedure for teachers, trainers and in company mentors to ""update their skills and competences in order to train apprentices according to the latest teaching and training methods and labour market needs"". In-company WBL mentors are in the core of quality WBL. However, in-company WBL mentors, in most European countries, lack standardized support and guidance which will set the expectations and boundaries clarifying and ensuring their successful contribution in the learning process. Thereby it poses administrative barriers to achieving the EU's targets for the promotion of a coordinated, unified network system on vocational education and the targets of the LLL-program to bolster cross-border mobility of workers. Based on the above and also the identification of the WBL needs and gaps by NetWBL, there is a significant need for the development of standards and qualifications identifying certain knowledge, skills and competences providing adequate assessment that will lead to valid certification ensuring quality in-company WBL mentorship by enterprises providing apprenticeships and internships. This proposal aims to: -develop ECVET compliant qualifications for trans-sectoral vocational skills, knowledge and competences necessary for qualifying high quality in- company WBL mentorship -boost the skills of in- company WBL mentors, while recognising prior learning which is now underdeveloped and non-qualified, through on-line training based on innovative learner-centred approaches incorporating the use of ICT -develop VET business partnerships for ensuring labour market relevance through high quality WBL provision from companies and accessibility to continuing VET learning -enhance, through a European certification scheme for workplace mentors based on a European skill card for mentors, transparency, recognition and validation of skills and qualifications via innovative e-assessment methods through the development of an online platform dedicated to competences examination -enhance prior learning facilitating the transition from education to work. Under the aforementioned rationale, #Mentor4WBL@EU project's partners were chosen based on their previous or current EU projects' involvement, their skill sets and their ability to deliver the project outputs. The consortium is composed by partners experienced in EU-projects such as, employers organizations (IME GSEVEE), public authorities (OAED), Certification bodies (EFCoCert), SMEs (ViaSyst and C4FF), Universities (BAU) and VET providers (IEK Aigaleo). The methodology followed by the project aims in the fulfillment of a twofold target. The first, to assure the validity and acceptability of project's results among the partners. The specific procedure will be guaranteed through the creation of a Steering Committee composed of project's partners, that will meet on a regular basis (e.g. managerial meetings, virtual workspace). The second to involve as many related stakeholders as possible, in order project's outputs to gain in validity and expertise. Thus, three multiplier events (i.e. United Kingdom, Turkey and Greece) and a final conference (Greece) will take place, in order a broader debating procedure to be implemented. In the framework of the project a number of IOs will be produced: -Course and Syllabus design for WBL mentors -Mentor Certification Scheme -E-course content development and platform -IT platform for online competence certification -Testing of the training and of the certification scheme -Exploitation report Finally and based on the previous mentioned activities, project's main impact can be summarized as follows: -development of skills and competences of in company WBL mentors -Improving the quality of apprenticeship and traineship -Transform of SMEs into quality WBL venues -Boosting of the ""culture"" of cooperation, LLL and certification for in-company trainers based on a common methodology -usage and dissemination of e-learning platform (and course) by the involved partners within national level -certification of mentor competences available in all Europe; - increase number of mobilities of certified mentors in Europe; - exploitation of the mentor certification scheme manual and of the e-assessment platform by other stakeholders (e.g. PCBs, national relevant authorities);"
