In their original model, the Curriculum Enrichment Activities (AEC) emerge as a programme dedicated to primary school students (1 to 4th grade) aimed at promoting the operationalization of the “full-time school” concept. Despite subsequent changes (in particular in 2008, 2011 and 2013), the programme was based on the idea of offering these children a set of activities that could enhance their personal development. This was one of the structuring lines of the programme, defining that the activities implemented should be properly framed from an educational point of view to ensure that they would function as a complement to the other basic acquisitions associated with “curricular” learning.
