In a major restructuring of the Jewish day school organizational world, five national groups that run a range of educational and programming activities for day schools have agreed to merge into a new, and potentially more effective, entity, The Jewish Week has learned. The merger, estimated to be completed this summer, could result in a cost savings of $1 million (as well as some job losses). It consolidates the work of PARDES (Day Schools of Reform Judaism), PEJE (the Partnership for Excellence in Jewish Education), RAVSAK (The Jewish Community Day School Network), the Conservative movement’s Schechter Day School Network, and the Yeshiva University School Partnership (YUSP). Collectively, the organizations serve about 40 percent of the day school students nationwide.
