Society in general and schools in particular continue to express their concerns with regard to the many challenges posed nowadays by living in a globalized world, where learning to coexist involves knowing oneself and those around us. Therefore, the professionals from the education sector and specially from the most vulnerable contexts demand the necessity to know strategiesand initiatives which enable them to build a democratic school, where learning to coexist is the key to educate engaged citizens living in an increasingly intercultural, changing world. The study presented here has been conducted in two differentiated, butcomplementary, phases. During the first phase a document search has been conducted on two inter-connected concepts: education and democracy, reviewing the theoretical and conceptual contributions from prominent authors, both national and international. During the second phase we have selected a series of peer and cooperative support strategies, as we consider them to be most appropriate to transform the school of today and tomorrow. We have stated their characteristics and their implementation possibilities. Class Assembly, Peer Support Program, Pair Reading, and Alternative Leisure to the Playground, are just some of those selected. It must therefore be concluded that building a democratic school is the way towards quality in education, by opening the school to participation through strategies which give a voice tothe whole education community.
