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, ensuring that graduation rates are reported at the charter school and secondary school site levels, as well as in aggregate and disaggregated by subgroups as required by the Every Student Succeeds Act.

Additionally, the bill outlines the process for removing a student from a cohort, specifying that written or electronic confirmation is required from a charter school or school district when a student transfers, emigrates, or is deceased. The confirmation must document the student's enrollment in another educational program or institution recognized by the Oklahoma State Regents for Higher Education. The bill also clarifies that students not enrolled in a recognized program 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.
