Given the closure of schools due to the global confinement resulting from the COVID-19 crisis, family-school cooperation has become a priority in most educational stages, but especially in Early Childhood Education and Care. This research analysed how parents dealt with this new situation, as well as the way in which family-school cooperation was established. Two online questionnaires were developed by the researchers. Respondents included 1266 families with children between the ages of infancy and six years, as well as 1235 early childhood education teachers from all regions of Spain. Results show that family-school cooperation is associated with several family and school characteristics and that families have neither the tools to face this new situation, nor the time to educate their children at home. This, together with the fact that some households do not have Internet access, makes family-school cooperation a challenging matter, especially in times of pandemic.
