The involvement of families in Spanish schools is a legally recognised right, a social demand, an educational need and a permanent challenge. However, there are limited opportunities for families to become engaged with schools in Spain. Their primary avenues for involvement are Parents’ Associations ( Asociaciones de Madres y Padres de Alumnos, known as AMPAs), but there has been little research on them to date. This article describes a qualitative study carried out in collaboration with 36 AMPAs from Spanish state schools, aimed at understanding how their members describe, interpret and assess their current situation. The findings showed that AMPAs foster activities to galvanise schools, but that they demanded increased decision-making powers, additional training and support in managing the association. It can be concluded that AMPAs are a means of promoting significant parental involvement, which merits further study and a wider social dissemination.
