As specified in the General Education Law, school providers have the right to establish and implement an educational project (Proyecto Educativo Institucional, PEI) and to establish plans and programmes for their schools with the involvement of the school community (see Chapter 1). Schools are therefore typically responsible for decisions directly related to the implementation of the school project, such as class size (within the regulated minimum and maximum size), student grouping, support for students with learning difficulties, school leadership arrangements, and the use of school facilities. In addition, school providers may delegate further tasks and responsibilities to schools, while retaining the final overall responsibility for the operation of their schools. For example, schools may make suggestions for staffing decisions, but the school provider will take the final decision.
