A few obvious problems: 1. What happens to the students who do not agree with that particular rabbi or spiritual leader? There are few schools whose staff and student body have exactly the same needs. 2. If there is money available for this, perhaps there is money for the nurse attached to each school [nurses were taken out of the schools several years ago]. They nurses are needed on a daily basis.
