Measuring Student Growth in Tennessee: Understanding TVAAS | Page 8
OCTOBER 2014
TAKING NOTE
RECENT POLICY CHANGES
Tennessee’s First to the Top Act was passed with
bipartisan support in 2010, laying the foundation for
the state’s successful Race to the Top application. As
noted previously, a new teacher evaluation system
was an integral component of the First to the Top
PAGE 8
Act. Since early implementation of the new teacher
evaluation system, the Tennessee Department of
Education has continuously revised the teacher
evaluation model based on feedback from teachers
and principals.41 Table 6 outlines these revisions along
with other policy developments related to TVAAS and
the teacher evaluation:
Recent Policy Changes
Inclusion of students with disabilities
Initially, students with disabilities were not included in individual teacher growth scores on the evaluation. Recent research in
Tennessee indicates that for 97 percent of teachers, the inclusion of students with disabilities in value-added measures does not
yield significant change in teachers’ overall scores. For this reason, legislation was changed to include students with disabilities in
individual teacher growth scores, providing student growth measures for additional groups of teachers.42 This shift in legislation only
applies to students who take end-of-year assessments based on their individualized education plans.
Alternative for teachers with high value-added scores
Legislation passed in 2013 allows teachers who received a one-year score of 4 or 5 on TVAAS to use TVAAS to account for 100
percent of their evaluation if it would result in an overall increase in their evaluation score.43
Classroom observation requirements
for the lowest-performing teachers
After the first year of implementation, school leaders indicated they wanted to spend additional time with those teachers who
needed greater support and assistance. For this reason, beginning in 2012, teachers who received a 1 on their evaluation were
required to be observed a minimum of four times a year.44
Customization options for districts
Districts can utilize an approved alternative teacher evaluation model or submit customized evaluation plans to the state that more
effectively align with local values and needs. These customized plans must align with the minimum requirements in state law, but
provide districts with additional flexibility in the measures used in their teacher evaluations. About one-third of Tennessee’s districts
customized their evaluation systems.45
VALUE-ADDED OPTIONS FOR TEACHERS IN NON-TESTED GRADES AND SUBJECTS
Tennessee approved alternative assessment options that qualify for student growth measures for teachers of traditionally nontested grades and subjects. These options include portfolio models, alternative assessments, and more accurate school-wide
measures. As a result, the population of teachers receiving individual growth scores increased from 30 percent to 50 percent.46 47
