Education - As enacted, prohibits the department of education from excluding from the calculation of a school letter grade the data of any group of students within a school if the department collects, aggregates, and reports the data, and if the group of students has at least 20 valid test scores in math or English language arts for at least one grade band; and data for the college and career readiness indicator if the school has at least 20 students in a graduating cohort. - Amends TCA Title 49.

SB 196 requires Tennessee's Department of Education to include all student group data in school letter grade calculations when specific thresholds are met. It directly affects public schools serving grades 9-12 that collect standardized test data, mandating inclusion of math/ELA scores for groups with at least 20 valid test scores in a grade band, and college/career readiness data for graduating cohorts of 20+ students. The bill amends Tennessee Code Annotated Title 49 to prevent exclusion of such data from school performance ratings. It became effective July 1, 2025, ensuring transparency in how school grades reflect student subgroup performance. This policy change focuses on data inclusion standards for accountability purposes, not educational content or funding.
