The requirements for conversions vary somewhat within the different branches of Judaism, so whether or not a conversion is recognized by another denomination is often an issue fraught with religious politics. The Orthodox rejection of non-Orthodox conversions is derived less from qualms with the conversion process itself, since Conservative and even some Reform conversions are ostensibly very similar to Orthodox conversions with respect to duration and content, but rather from that the convert was presumably not properly (i.e. according to tradition) instructed in Jewish Law, and the procedure of conversion has a chance of not having been done properly, and that those overseeing the process were (almost certainly) not qualified to test the convert (and in any case would have had different answers).[original research?]
