An educational program called Nativ is offered to Israeli soldiers and officers who are not Jewish according to Halacha (Orthodox Jewish law) during their military service. The program commences with a seven or eleven-week intensive course in Judaism to prepare them for conversion. After completing the course and being sent back to their bases, soldiers interested in proceeding with the conversion process are then invited to two two-week seminars, with a month off between them, before undergoing the official conversion by three rabbis of the IDF Chaplaincy.
