  10. Purchases made with federal or State awards must comply with 2 C.F.R. Part 200 and 30 ILCS 708/, as applicable, and any terms of the award.

The Superintendent or designee shall: (1) execute the reporting and website posting mandates in State law concerning District contracts, and (2) monitor the discharge of contracts, contractors’ performances, and the quality and value of services or products being provided.


All contracts for supplies, materials, or work involving an expenditure shall be made in accordance with the Illinois School Code. When bidding is required, the contract is to be awarded to the "lowest responsible bidder."

The contract is awarded by vote of the Board at an official meeting. The superintendent or his designee shall report the results of the bidding to the Board, together with a recommendation regarding acceptance. Whenever the lowest bid is not recommended, “as the lowest responsible bid” justification shall be provided. Bid deposits of 10 percent of the bid amount, assuring good faith in bidding, and performance bonds to the extent of 100 percent of the bid amount, may be required.

In an emergency, expenditures without bids may be made in accordance with State of Illinois law. Under this provision, the superintendent may authorize purchase of remedial goods or services in cases where personal health and/or safety are judged to be endangered, or property damage is imminent. Such action shall require approval of three-fourths of the Board.

It shall be the practice whenever possible to solicit competitive written quotations for purchases in excess of $25,000 in order to secure the lowest prices and to make the best use of the District funds.


For the purpose of securing bids or quotations on items to be purchased, specifications shall be written in such a manner as to insure, as far as possible, that the products offered for sale are acceptable for the intended purpose. However, specifications should be as broad as possible to permit competition, consistent with quality and design desired.

In some instances, the clearest specification may be the naming of a brand product or model number, with the additional qualification "or equal" to indicate that consideration will be given to items of similar manufacture, design, and quality.

A product or service may be restricted to a specified vendor or manufacturer when required for educational purposes, standardization, or otherwise in the best interest of the schools.


It shall be the policy of the District to purchase locally, provided goods of equal quality and at competitive prices are available from local suppliers.

Nevertheless, the District purchasing agent, is not bound to purchase any item locally that can be secured at a savings to the District from outside sources, nor shall he /she be bound to purchase locally unless adequate service and delivery can be provided by the local supplier.


During the performance of a contract with the District, a contractor shall, as a term and condition of the contract, comply with all applicable local, state, and Federal laws.


All bills for goods, services, salaries, expenses, or other items must be approved by the Board in advance of payment except when paid for from the Revolving Fund.

A listing of all such bills shall be prepared monthly and shall be furnished to Board members in advance of the Board meeting. Each amount presented for payment shall carry an identifying purchase order number, the name of the person or firm to whom the payment is to be made, and the code number of the budgetary item to which payment shall be debited. Approval shall be given by a Board resolution and vote, and bills so approved shall be recorded in the minutes of the meeting.

A copy of the resolution of approval, signed by the president and the secretary, shall be transmitted to the Township School Treasurer, as his/her authority to make the payments as ordered.


In all procurement activities, Board members and District employees shall:

  1. Endeavor to obtain the greatest value for every tax dollar expended.
  2. Give all responsible bidders equal considerations and unbiased judgment in determining whether their product meets specifications and the educational needs of the school system. There shall be no discrimination toward vendors on account of color, race, nationality, religion or religious affiliations, age, sex or disability.
  3. Discourage the offer of, and decline to accept gifts or gratuities from vendors who are supplying or who might seek to supply the school district. Professional samples and advertising items should not exceed $50 value, and business luncheons should not exceed $75 per person.
  4. Refrain from soliciting funds, material, or favors from vendors, however worthy the purpose.
  5. Any gifts or gratuities offered to family members of Board members or employees is prohibited.


All purchases of goods, services, and equipment for which the District will be responsible for payment, except purchases made from Petty Cash funds, shall be made on official purchase orders, properly executed. Official purchase orders may be requested for Petty Cash purchases when deemed in the best interest of the District.
