The Rabbinical Council of Bergen County last week unanimously voiced its support of a community fund to raise money for day schools struggling with rising costs and skyrocketing tuitions. Following the vote, the Northern New Jersey Tuition Crisis Committee, the group of day school representatives and rabbis that proposed the kehilla fund, its unofficial name, filed incorporation papers to create Northern New Jersey Jewish Education for Generations Inc. The nonprofit organization will manage the fund — to be called Northern New Jersey Kehillot Investing in Day Schools, or NNJKIDS.
