Local churches also are members of larger "Conferences", of which there are 36 in the United Church of Christ. A conference typically contains multiple associations; if no associations exist within its boundaries, the conference exercises the functions of the association as well. Conferences are supported financially through local churches' contribution to "Our Church's Wider Mission" (formerly "Our Christian World Mission"), the United Church of Christ's denominational support system; unlike most associations, they usually have permanent headquarters and professional staff. The primary ecclesiastical function of a conference is to provide the primary support for the search-and-call process by which churches select ordained leadership; the conference minister and/or his or her associates perform this task in coordination with the congregation's pulpit search committee (see above) and the association to which the congregation belongs (particularly its ministerial committee). Conferences also provide significant programming resources for their constituent churches, such as Christian education resources and support, interpretation of the larger UCC's mission work, and church extension within their bounds (the latter usually conducted in conjunction with the national Local Church Ministries division).
