The Central Conference of American Rabbis (CCAR), founded in 1889, is the principal organization of Reform Jewish rabbis in the United States.
It largely consists of rabbis educated at Hebrew Union College-Jewish Institute of Religion, but also offers memberhip to those who graduated in Europe from the Leo Baeck College in London (United Kingdom) and the Abraham Geiger College at the University of Potsdam (Germany), and others who joined the Reform movement after being ordained. Most of the last group graduated from either the Conservative Jewish Theological Seminary of America or the Reconstructionist Rabbinical College.
The CCAR issues responsa, resolutions, and a platform. It is also the publisher of CCAR Journal, a journal of Reform Judaism published quarterly. The group also owns CCAR Press, a large publisher that produces Reform siddurs, machzorim, and haggadahs with a mixture of Hebrew and English. The most well-known CCAR prayerbooks include Gates of Prayer, Gates of Repentance, and the soon-to-be published Mishkan T'filah.
