The National Society of Children's Nurseries (NSCN), originally known as the National Society of Day Nurseries, was founded in 1906 (the name was changed in 1942). Until 1928 it was closely linked with the National League for Physical Education and Improvement (known from 1918 until its dissolution in 1928 as the National League for Health, Maternity and Child Welfare). The Nursery School Association of Great Britain and Ireland (NSA) was founded in 1923. In 1973, it merged with the NSCN to form the British Association for Early Childhood Education (BAECE).
