IRS990ScheduleI/SupplementalInformationDetail/ExplanationTxt0ALL FAMILIES HAVE THE OPTION OF APPLYING FOR FINANCIAL ASSISTANCE (FA) AT THE SAME TIME THAT THEY APPLY FOR ADMISSION TO PROOF SCHOOL. THE FA PROCESS IS HANDLED BY SSS, AN INDEPENDENT SERVICE USED BY MANY SCHOOLS TO DETERMINE FINANCIAL ASSISTANCE AWARD AMOUNTS. ONCE A STUDENT IS ADMITTED, OUR FA COMMITTEE USES INFORMATION PROVIDED BY SSS AND BY THE FAMILY IN ORDER TO MAKE FINAL AWARD DETERMINATIONS, WHICH ARE SHARED IN THE ENROLLMENT AGREEMENT. ALL RECORDS RELATED TO FA ARE KEPT ELECTRONICALLY, BOTH VIA SSS AND INTERNALLY.
