Since 1993, TVAAS has provided Tennessee educators and policymakers with a powerful tool to determine—grade by grade and subject by subject—whether all students have increased opportunities for learning. These analyses follow the growth of individual students over time to:

  • Assess systems', schools', and teachers' influence on student growth; and

  • Provide trajectories for individual students toward critical academic benchmarks.

Through the Tennessee Department of Education (TDOE), this reporting is available to every system, public school, and charter school in the state via a secure web application.

The value-added estimates provided by TVAAS are based on robust and reliable methodologies. This important approach overcomes many critical statistical issues related to using standardized tests to assess student growth and mitigates concerns about fairness.

The information in this document is based on the typical TVAAS reporting and includes results from the 2018-19 school year. Due to the pandemic's impact on student learning, the models, interpretation, and results from the 2020-21 and 2021-22 reporting might differ somewhat than what is described here.
