Education, Dept. of - As introduced, requires the department to use student performance on career readiness assessments administered to high school seniors as part of the school grading system if the department uses student performance on postsecondary readiness assessments for such purpose; directs the department to only consider student performance on the assessment type for which the student achieved the highest score for school grading purposes, if the student was administered a postsecondary readiness assessment and a career readiness assessment. - Amends TCA Title 49.

HB 90 amends Tennessee's school accountability system to require the Department of Education to include career readiness assessment scores (like industry certifications or vocational tests) alongside college readiness tests (like ACT/SAT) when calculating school grades. It directly affects Tennessee high schools and seniors who take both types of assessments, mandating that schools use only the student's highest score from either test for grading purposes. The bill ensures schools consider both career and college readiness metrics equally, preventing schools from relying solely on one test type. This change applies to school grades issued for the 2025-2026 school year and beyond.
