In order to make mobility truly effective, all the learning outcomes achieved abroad by the student - by practical as well as theoretical training- should be recognised in the home school.This project implemented a tool to promote student’s mobility by facilitating within the participant schools the validation of the knowledge, skills and competences gained during his staying abroad for a concrete period of time: a term.The main value of this handbook is that it empowers head teachers from other schools to design with precision the mobility of their students, by choosing only the learning units of interest regardless of whether they are from two different subjects, or from two different specialties. The work area is centered in specialties related to Industrial Maintenance.As expected, the student mobility improves both quality and quantity-wise due to the tools developed during the project. These tools help to organise the mobility and guarantee the quality. In this way it will be easier to validate all the competences acquired. In addition, transparency of education and training programs increased. By the end of the project, we were able to involve other schools in Europe related with the same specialties in such kind of mobility.In this project participated 6 well-known VET schools from 6 different countries, a Consortium of Educational institutions, all of them with experience in developing European projects.
