  The board of directors of a school district may adopt a program for payment of a monetary bonus, continuation of health or medical insurance coverage, or other incentives for encouraging its employees to retire before the normal retirement date as defined in chapter 97B. The program is available only to employees who notify the board of directors prior to April 1 of the fiscal year that they intend to retire not later than the start of the next following school calendar. The age at which employees shall be designated eligible for the program shall be at the discretion of the board.
