Within ten days of receipt of a petition filed under section 296.2, the president of the board of directors shall call a meeting of the board. The meeting shall be held within thirty days after the petition was received. At the meeting, the board shall call the election, fixing the time of the election, which may be at the time and place of holding the regular school election. However, if the board determines by unanimous vote that the proposition or propositions requested by a petition to be submitted at an election are grossly unrealistic or contrary to the needs of the school district, no election shall be called. If more than one petition has been received by the time the board meets to consider the petition triggering the meeting, the board shall act upon the petitions in the order they were received at the meeting called to consider the initial petition. The decision of the board may be appealed to the state board of education as provided in chapter 290. The president shall notify the county commissioner of elections of the time of the election.
