Bill No. 409, introduced by Senators Pugh and Caldwell, amends Section 1-109 of Title 70 of the Oklahoma Statutes regarding the length of the school year and classroom instruction requirements for public schools. The bill stipulates that, starting July 1, 2025, if the amount appropriated to the State Board of Education for public school support exceeds the previous fiscal year's funding by at least $25 million, school districts must offer an additional day of classroom instruction. This amendment is intended to enhance educational opportunities in response to increased funding.

Additionally, the bill clarifies existing provisions related to the minimum number of instructional days and hours, allowing for flexibility in school hours policies adopted by district boards of education. It maintains the requirement for a minimum of 180 days or 1,080 hours of instruction while also detailing conditions under which professional meetings and parent-teacher conferences can be counted towards instructional time. The bill emphasizes the importance of documenting student achievement in relation to any extended-day schedules adopted by school districts, with consequences for failure to demonstrate improvement.
