The teaching of sick children in hospital is an often overlooked aspect of Ireland's national education system. Prior to the 1970s, there was hardly any formal structure in place for this type of schooling in the country, despite the fact that many children could be inpatients for weeks or months at a time. In 1980, a report, published by the Association for the Welfare of Children in Ireland, revealed that although there had been an improvement in the intervening decade, only 6% of hospitals had a dedicated schoolroom. Drawing on previously unresearched papers belonging to Temple Street Children's Hospital, this article will take a closer look at the socio-political forces that held back the development of the hospital classroom in Ireland for so many decades; it will also explore some of the factors that promoted its development after 1970, thus helping to explain why the education of sick children is so firmly established today.
