The Tennessee Value-Added Assessment System (TVAAS) measures student growth year over year, regardless of whether the student is proficient on the state assessment. In calculating a TVAAS score, a student’s performance is compared relative to the performance of his or her peers who have performed similarly on past assessments.

Access TVAAS Reports

Value-added is a statistical analysis used to measure the impact of districts, schools and teachers on the academic progress rates of groups of students from year-to-year. Conceptually and as a simple explanation, a value-added "score" is calculated in the following manner:

  • Growth = Current Achievement/current results compared to all Prior Achievement/prior results; with achievement being measured by a quality assessment such as the TCAP end of grade Achievement and end-of-course tests.

  • The methodology used in Tennessee for value-added assessment was developed twenty years ago at the University of Tennessee, Knoxville. Simple models for value-added assessment yield results that may be confounded by measurement error and exclude students who have missing data in their assessment history.

  • The methodology used by TVAAS is called the Tennessee Value-Added Assessment System (TVAAS). The TVAAS methodology has been published since 1997, and these models have been nationally peer reviewed.

  • To help you understand TVAAS analysis, think of academic progress/growth in terms of a child's physical growth, and the growth charts utilized by a child's physician. Growth charts are an important tool for monitoring a child's development, but they are just one of the indicators used by the physician to ensure a child is growing at the minimum expected level and on the trajectory to grow as expected. A physician would not use a growth chart in isolation to diagnose a child; however, the growth chart would provide valuable information that may warrant further exploration.

    TVAAS provides two types of information, value-added (or growth) data on cohorts of students and student level projection data.

    The value-added, or growth, analyzes available data from previous years (looking back) to help schools evaluate how much cohorts of students have gained in a school year by answering questions such as: Did a group or subgroup of students make a year's worth of growth for a year's worth of schooling?

    The projection data uses the data already analyzed to help schools project (looking forward) to the future by answering questions such as: What is the percent likelihood of a student being proficient on a future TCAP end-of-grade Achievement, end-of-course or college readiness exam? Projection data can be used for intervention planning and resource reallocation.

    TVAAS is available for the following test areas for elementary schools:

    • English language arts, math, and science in grades four through eight

    • English language arts and math in grades one through three (only for districts who opted to administer the K-2 assessment, formerly known as SAT 10)

     

    TVAAS is one of the many tools provided to districts from the Tennessee Department of Education. Districts and schools are using TVAAS, in conjunction with achievement data, to make sure all students are on the trajectory to proficiency. Utilizing all the data available (progress and achievement), educators are able to make data-informed instructional decisions to ensure the academic growth and achievement of all students.
