HB 297 amends the Texas Education Code to remove certain state-mandated end-of-course (EOC) assessment requirements for high school graduation that are not federally mandated. Specifically, the bill eliminates EOC assessments in English II and United States History, reducing the number of mandatory state-level exams to Algebra I, Biology, and English I. Additionally, the bill specifies that students do not need satisfactory EOC scores in English II or U.S. History to receive a high school diploma. HB 297 also prohibits school districts and charter schools from requiring satisfactory EOC performance in these subjects for graduation, although school boards may readopt such requirements for future students after the bill’s effective date. The Act is set to apply from the 2025-2026 school year onward​.
