(1) Student performance on the Tennessee comprehensive assessment program (TCAP) tests or end-of-course exams;
(2) Student growth as indicated by Tennessee Value-Added Assessment System (TVAAS) data or data from other measures of student growth; and
(3) Other outcome indicators of student achievement that the department finds to be reliable measures of school performance.
(b) The department of education shall include each school's A, B, C, D, or F grade on the state report card.
(c) Implementation of the school grading system shall begin in the 2017-2018 school year; provided, however, prior to implementation, the state board shall review the grading scale developed by the department.
(d) The department shall provide notice of the adopted grading scale to each LEA prior to the start of the 2017-2018 school year.
(e) Notwithstanding subsection (a), student performance and student growth data from the TNReady assessments administered in the 2017-2018 school year shall not be used to assign a letter grade to a school pursuant to this section.
