It is the duty of the father to have his child circumcised; and if he fails in this, the beth din of the city must see that the rite is performed. According to traditional Jewish law, in the absence of a grown free Jewish male expert, a woman, a slave, or a child, that has the required skills, is also authorized to perform the circumcision, provided that she or he is Jewish. However, most streams of non-Orthodox Judaism allow female mohels, called "mohalot" (, plural of "mohelet", feminine of "mohel"), without restriction. In 1984, Deborah Cohen became the first certified Reform mohelet; she was certified by the Berit Mila program of Reform Judaism.
