Most play schools in Ireland are in the private sector. Increasingly, children of working parents, who are below school age; attend a myriad of crèches, play-schools, Montessori schools, etc., which have sprung up in response to the changing needs of modern families. These operate as businesses and may charge often substantial childcare fees. Since 2009, in response to public demand for affordable childcare, children may receive two years free preschool the years prior to starting primary schools under the "Early Childcare and Education Scheme".
