Iowa Code § 277.7: Petitions for public measures.

1. A petition filed with the school board to request an election on a public measure shall be examined before it is accepted for filing. If the petition appears valid on its face it shall be accepted for filing. If it lacks the required number of signatures it shall be returned to the petitioners.

2. Petitions which have been accepted for filing are valid unless written objections are filed. Objections must be filed with the secretary of the school board within five working days after the petition was filed. The objection process in section 277.5 shall be followed for objections filed pursuant to this section.
