A bill for an act modifying the earliest possible start date of the school calendar for school districts and accredited nonpublic schools.

This bill modifies Iowa's school calendar start date by changing the earliest permitted start from August 23 to the Monday immediately preceding the last Monday in August (typically mid-August). It directly affects all public school districts and accredited nonpublic schools in Iowa, requiring them to set calendars that begin no earlier than this new date while maintaining the existing 180-day instructional requirement. Key provisions include mandating public hearings for calendar changes and allowing schools to excuse graduating seniors from extended calendars due to weather closures. The bill does not alter the minimum instructional days or online learning limits but adjusts the earliest possible start date.
