Developmental Centre of Thessaly is a certified provider of VET training by the National Organisation for the Certification of Qualifications & Vocational Guidance (EOPPEP), provide and support structured learning activities that are addressed to VET and adults and aim to enrich knowledge, to develop and improve skills and competencies, to the development of individual's personality and the sense of active civic, and to reduce the cultural and social inequalities. Particular emphasis is given to the importance of education of members of vulnerable social groups.The term "vulnerable groups" is closely connected to the concept of social exclusion, since people who are members of these groups are considered as vulnerable to poverty and social exclusion. Education and training in general contribute not only to the prevention of social exclusion by providing main education and the necessary initial professional training that is required for the smooth transition of members of vulnerable groups in the labor market, but also to tackling unemployment and to the social integration of members of vulnerable social groups.Our organization, perceiving the importance of additional training and education of members of vulnerable social groups and the complex and challenging role of the instructor, decided to submit a plan under the ERASMUS+ program and the Action KA1 VET education staff mobility. The objective of the proposed project is to train 10 VET educators, staff of the organization, in modern methodologies and practices in education of members of vulnerable social groups.Since in our country specialized seminars that are related to the training of VET educators in the field of education of members of vulnerable social groups are not conducted, the proposed project will complement the training of teachers and will provide them with the necessary tools for the integration of modern teaching methods in the educational process that should be followed in the field of socially vulnerable groups’ education.Through the proposed project, our organization will acquire a labor force of VET educators with high quality and internationally recognized (through ECVET acquisition) training in the field of education of members of vulnerable social groups. In this way all the necessary conditions related to the support of socially vulnerable groups and tackling social exclusion will be created.The proposed project mainly concerns the implementation of a specialized and structured training seminar (2 weeks, 50 hours) concerning modern methodologies and practices in education of members of vulnerable social groups. The seminar is consisted of both theoretical and observation period (job observation) in institutions that deal with vulnerable social groups and VET training. The participants will have the opportunity to observe the practical application of the knowledge and skills they acquired during their theoretical training.
