In spite of the importance of culture and museums in European Union's identity and economy, the role of the cultural mediator is still undervalued. Across Europe, the Museum and Heritage Educators are highly qualified professionals with fragile relations with the employer, with very diversified academic and museum contexts, most of whom with little or none communication and education training skills.The main goal is to create a training course for Museum Mediators/ Educators, that represents the institutional and professional needs of Museums' mediation professionals in the European countries that participate in the project: Portugal, Spain, Estonia, Finland and Italy. Mapa das Ideias will export the training course that was tested in Portuguese (2009, 2010, 2011) and European (Loures, Oporto, Brussels, Barcelona sessions) settings, with an international team of lecturers. By developing this common training ground among Museum professionals in the five participating countries, the project will stimulate the creation of training and professional guidelines that will sustain the work of Museum Mediation and Education officers.
