In Denver, Colorado, a joint Orthodox, Traditional, Conservative and Reform Bet Din was formed to promote uniform standards for conversion to Judaism. A number of rabbis were Orthodox and had "semicha" from Orthodox yeshivas, but were serving in synagogues without a mechitza; these synagogues were called "traditional Judaism". Over a five-year period they performed some 750 conversions to Judaism. However, in 1983 the joint Beth Din was dissolved, due to the unilateral American Reform Jewish decision to change the definition of Jewishness.
