N.J. Stat. § 18A:18A-55
Notwithstanding the provisions of any law to the contrary, a board of education which has established a small business enterprise set-aside program, a minority business enterprise set-aside program or a women's business enterprise set-aside program shall designate that a contract, subcontract or other means of procurement of goods, services, equipment, or construction shall be awarded to a small business enterprise, a minority business enterprise or a women's business enterprise, if the board is likely to receive bids from at least two small business enterprises, minority business enterprises or women's business enterprises, as appropriate, at a fair and reasonable price.
The designations shall be made prior to any advertisement for bids, if required. Once designated, the advertisement for bids, if necessary, shall indicate that the contract to be awarded is a small business enterprise set-aside contract, a minority business enterprise set-aside contract or a women's business enterprise set-aside contract, as appropriate. All advertisements for bids shall be published in at least one newspaper which will best provide notice thereof to small business enterprises, minority business enterprises or to women's business enterprises, as appropriate, sufficiently in advance of the date fixed for receiving the bids to promote competitive bidding, but shall not be published less than 10 days prior to that date.
