Increases the required number of instructional days in a school year to two hundred

This bill increases New York State's required school year length from 180 to 200 instructional days for public schools. It amends multiple sections of the Education Law to update this requirement, directly affecting all public school districts and their funding calculations. Key provisions include adjusting funding formulas to reduce payments for days below 200, with limited exceptions for extraordinary weather, emergencies, or school closures that prevent makeup days. The bill also modifies waiver processes for summer prekindergarten programs operating outside the standard school year.
