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.

HB 392 requires Tennessee schools to include student performance data for specific groups in their letter grades if those groups meet minimum thresholds: at least 20 valid math or English language arts test scores in one grade band, or 20 students in a graduating cohort for college/career readiness data. This applies to schools serving grades 9-12 with qualifying student groups, ensuring the Department of Education cannot exclude such data from school ratings. The bill amends Tennessee Code Annotated Title 49 to standardize how school performance is measured. It takes effect July 1, 2025.
