About School Letter Grades
T.C.A. § 49-1-228, passed in 2016, required the department to develop a school letter grade rating system to provide parents and families with information that shows how Tennessee public schools are performing. The state’s letter grade legislation is intended to provide a snapshot of how each school performed during the previous academic year and compare those results over time.
The calculation to generate school letter grades for schools includes four indicators: student achievement, student academic growth, growth of the highest need students and college and career readiness just for high schools. Schools receive an indicator score for each of the indicators, ranging from levels 1-5. Each indicator score is multiplied by a weight based off the grade band to create a total score, which is then used to determine the school’s letter grade.
Additional information and resources on School Letter Grades can be found on the department’s School Letter Grades webpage.
