This bill amends 70 O.S. 2021, Section 3-151.1, to establish a uniform definition of high school graduation rates applicable to school districts, secondary schools, and charter schools in Oklahoma. The State Board of Education is tasked with adopting and implementing both a four-year adjusted cohort graduation rate and an extended-year adjusted cohort graduation rate. The bill updates statutory references to align with the Every Student Succeeds Act and specifies that graduation rates must be reported both in aggregate and disaggregated by subgroups as required by federal law.

Additionally, the bill outlines the procedures for removing a student from a graduation cohort, which now includes charter schools. Written or electronic confirmation is required to document a student's transfer, emigration, or death, with specific criteria for what constitutes valid confirmation. The bill also clarifies that students not enrolled in recognized educational programs will not be counted in the graduation rate calculation. The act is set to take effect on July 1, 2025, and includes an emergency clause for immediate implementation upon passage.
