Schools; requiring statewide assessments to be held in the last four weeks of each school year; effective date; emergency.
HB 4359 requires Oklahoma's statewide student assessments to be administered in May each year, rather than at other times of the year. This bill directly affects all Oklahoma public school students in grades 3-12, as it amends existing law governing the timing of required assessments in English Language Arts, math, science, and U.S. History. The key mechanism is a specific amendment to the statute requiring assessments to occur "in May" annually, while maintaining all other assessment content, grade-level requirements, and graduation criteria. This change aims to standardize assessment timing across districts for better planning and reporting. The bill does not alter what is assessed or the graduation requirements themselves.
