the public sphere. It has a get-like divorce document issued by its rabbinic court, and conversion requires circumcision by males and ablution by both sexes. Egalitarianism did not become prevalent in most synagogues until the 2000s, although the first female rabbi, Jackie Tabick, was ordained in 1975. Mixed seating was only accepted just before and during World War II. Recognition of Jews by patrilineal descent was affirmed in 2015. Reform Judaism currently ordains female and LGBT clergy, conducts LGBT marriages and has egalitarian services, counting women for minyan and allowing them full participation. Girls have their bat mitzvah at 13, the same age as boys have their bar mitzvah. Reform Judaism is welcoming to non-Jewish spouses; while the Assembly maintains "clear opposition" to involvement in interfaith unions, since 2012 it allows rabbis to conduct celebratory events as long as the ceremony does not involve clergy or motifs from other religions, or conversely those of a Jewish wedding, like a ritual canopy. Organisational structure As of 2021, Reform Judaism has 43 synagogues, of which 41 are located in England, and, among those, 13 in Greater London. There is one congregation in Cardiff and one in Glasgow. As of 2010, Reform Judaism had 16,125 member households, accounting for 19.4% of synagogue-affiliated Jewish families in Britain and roughly 14% of the total Jewish population. All of the synagogues are autonomous, owned and financed by their members who also hire their own local rabbi independently. All clergy are members of the Assembly of Reform Rabbis, which publishes Reform prayerbooks and determines policy in religious matters. The denomination is led by the Senior Rabbi, while the Chair of the Assembly represents and organises the rabbis. It maintains a rabbinical court (Beth Din), located at the Sternberg Centre in London. The Reform Beth Din's decisions are recognised worldwide by all WUPJ affiliates. Alongside the clergy, lay leadership is provided by a board of delegates, the chair of which represents Reform Judaism in the Board of Deputies. Reform Judaism trains its clergy at the Leo Baeck College, London, which is shared with the Liberals and the Masorti Assembly. While British Reform Judaism and British Liberal Judaism are both WUPJ affiliates and cooperate in many fields, such as outreach to the religiously non-active and interfaith families, the two stress that they "retain their autonomy and distinct identities".
