Joseph Caro ’s summation:"It depends upon the judgement of the bet din." If the rabbi believes that this is a sincere person who will maintain the affiliation with Judaism and that her willingness to continue instruction even after the marriage is a further evidence of her sincerity, then he may certainly shorten the period of instruction, especially when this is done temporarily.
But there is need for caution. Inasmuch as it is the instruction which has become the most important element for us, we must guard it carefully and not let it become a mere formality, lest it come down eventually to a few words of instruction in one interview and the candidate then be considered to be converted. If the shortening of the course is done in exceptional cases only and there is good reason for it, and if thereby the general practice of the instruction of proselytes is not by this one case weakened, then there is no reason why the rabbi may not use his judgment in the matter.
