The Cathedral Choir is supported financially by the St Olave's & St Saviour's Schools Foundation, which stems from the two parochial schools set up in the 1560s which still hold their commemoration and annual services at the cathedral as their 'foundation' church. As the cathedral does not have a choir school, the boys and girls of the Cathedral Choir are drawn from schools throughout London and surrounding areas. Girls are usually admitted to the choir between the ages of ten and eleven, and boys between the ages of seven and ten. There are six Lay Clerks in the Cathedral Choir and up to six Choral Scholars. Three of the Lay Clerks are supported by endowments from The Ouseley Trust, the Vernon Ellis Foundation, and the Friends of Cathedral Music.
