Since 1993, SAS EVAAS 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. TVAASanalyses follow the growth of individual students over time to:

  • Assess systems', schools', and teachers' influence on student progress; 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 a robust and reliable methodology. This important approach overcomes many critical statistical issues related to using standardized tests to assess student growth and mitigates concerns about fairness.
