Since the academic year 1998-1999, the city of Banyoles has been creating the conditions to ensure equal and inclusive education in its schools through an educational equity programme called the “Pla d’Escolarització Extensiva”. Based on the four principles of consensus, planning, awareness and resourcing, the programme has helped schools create more heterogeneous class groups and achieve school desegregation, making Banyoles one of the municipalities in Catalonia with the lowest rate of school segregation. The “Pla” was originally launched thanks to the agreement between the city’s institutions and school centres combined with the support of the Catalan government’s Ministry of Education. Twenty years later it has become a basic tool for educational planning that has made inclusive education a reality for students with specific educational needs across all the municipality and promotes equal opportunities in access to the city’s school centres. The key elements in this success are the programme’s preventive and predictive mechanisms, which were already an important part of its initial development, and the coordinated work of its members during the last twenty years. As a member of the International Association of Educating Cities, Banyoles strives to provide an adequate level of social inclusion and cohesion for all its citizens and the “Pla d’Escolarització Extensiva” has played a key role in achieving this, making it a valuable object of study.
