Modifies the required school year start date for school districts in which a charter school operates

HB 3310 establishes minimum requirements for school district calendars in most areas, mandating at least 169 school days (or 142 days for districts using a four-day week) and restricting start dates to no earlier than 14 days before the first Monday in September. It specifically excludes school districts operating charter schools from these rules, as outlined in the bill’s provisions. Violations could result in the state withholding 25% of a district’s state funding for each day of noncompliance. The bill also allows limited exemptions for unusual circumstances but does not apply to districts with year-round schedules or those operating charter schools.
