TVAAS

 

Description

The Tennessee Value-Added Assessment System (TVAAS) measures the impact schools and teachers have on their students’ academic progress. TVAAS is a powerful tool because it measures how much students grow in a year and shines more light on student progress than solely considering their score on an end of year test.TVAAS allows educators to consider their students’ achievement (their score on the end of year assessment), as well as their growth (the progress students make year to year).

 

Educators are only held accountable for the things that they can control, such as their students’ progress during the school year. Teachers are not held accountable for the things they cannot change, such as their students’ previous achievement. TVAAS only measures what a school can control.

How does TVAAS work?

 

When a teacher greets the class on the first day of school, students arrive at different academic levels – one student may struggle to sound out words while another reads complex novels. A teacher’s goal is to “add value” to students’ academic experience, meaning students in the class show growth. The expected progress for each student is unique and tailored to their own prior performance.

 

Because every child has different needs, a teacher adds value by differentiating instruction to meet the diverse needs of his or her students. A value-added measure is one tool to help an educator reflect on his or her teaching and identify the practices that met student needs, as well as the practices that did not meet student needs.

How can schools use TVAAS to improve?

 

  • Monitor the progress of all groups of students from low-achieving to high-achieving, ensuring growth opportunities for all students.
  • Measure student achievement as a result of the impact of educational practices, classroom curricula, instructional methods and professional development.
  • Make informed, data-driven decisions about where to focus resources to help students make greater progress and perform at higher levels.
  • Align professional development efforts to the areas of greatest need.
  • Identify best practices and implement programs that best meet the needs of students.
  • Celebrate growth with students and families.
  • Ensure that high-achieving students continue to be challenged.

How can teachers serving high-achieving students  score highly effective on TVAAS?

Student expectations are not built on a single score but on a progression of scores, so even the highest achievers are only expected to score in line with their own history of achievement. When teachers are effective, their students will not lose ground, even if their students are initially high achieving.

How can teachers serving low-achieving students  score highly effective on TVAAS?

TVAAS does not compare a student’s performance to a set standard, but compares the student’s performance to his or her own prior performance. For example, a school can have low achievement scores based on the TCAP, but have very high TVAAS scores.
