The initial terms and conditions of the employment contract between the boards and the superintendent or school business administrator shall be determined by the boards and the superintendent or business administrator. The terms shall be maintained for the life of the contract.
Boards may mutually agree to provide additional benefits or compensation during the life of the superintendent's or business administrator's contract, but if agreement is not possible, an individual board may do so unilaterally based upon the superintendent's or business administrator's performance and the needs of the district, and the responsibility for the cost of the additional benefits shall rest solely with that individual board.
