At CEIP Gomez Moreno Infant and Primary School -a recognised state school in Granada's Albayzin neighbourhood-, a group of parents, strongly committed to a Universal and Public education system as a tool to correct social inequalities, has taken on the direct management of complementary and extracurricular school services, in order to give back to society applying the specific skills and qualifications of the school community from a democratic and civic participation perspective.Among the services comprehensively and voluntarily managed by the parents' association (AMPA in Spanish), the most successful one having the highest impact on the educational community is the school's dining hall service, which includes the use of local and organic produce, as opposed to a general process currently taking place in Andalusia by which catering services subsidiary to large business groups are being widely implemented, leading to the indirect privatization of this public service.The results: the forceful assertion of public education, both inside and outside the community context, by means of a daily dining service with an on site kitchen serving locally sourced and organic meals; high levels of satisfaction from its users; the achievement of parents' empowerment, as co-responsible citizens for the proper functioning of the public education service in the path towards excellence; and the contribution to the consolidation of sustainable social models.
