N.J. Stat. § 18A:24-90
If the board of education of a school district or governing body of a municipality shall determine by resolution that a maturity schedule for its qualified bonds, other than the maturity schedule approved by the local finance board pursuant to section 4 is in the best interest of said school district, it may make application to the local finance board setting forth such belief and the grounds therefor and requesting approval of a schedule of maturities for such qualified bonds set forth in the application.
Within 60 days after submission to the local finance board of an application, the local finance board shall cause its approval to be endorsed thereon if it shall be satisfied, and shall record by resolution its findings, that the belief set forth in such application is well founded and that issuance of the bonds pursuant to the revised maturity schedule in such application would not materially impair the credit of any municipality comprised within the school district or substantially reduce its ability, during the ensuing 10 years, to pay punctually the principal and interest of its debts and supply essential public improvements and services. If the local finance board is not so satisfied, it shall cause its disapproval to be endorsed on such copy within said period of 60 days.
