From WATE in Knoxville:
NOXVILLE (WATE) - The Tennessee
Education Association has filed a lawsuit against the Knox County Board of
Education saying its use of Tennessee Value Added Assessment System estimates
in high-stakes bonus decisions is unconstitutional.
"It is unacceptable for any
teacher to be punished financially or otherwise as a result of unreliable, flawed
statistical estimates that can vary years after a student was in that teacher's
classroom," said Gera Summerford, TEA president.
TEA says Knox County teacher Lisa
Trout was unfairly denied the district's APEX bonus after being misled about
how her TVAAS estimate would be calculated.
TEA officials say a guidance
counselor incorrectly claimed 10 of Trout's students for her TVAAS score
without her knowledge, causing her to get a lower estimate than she should
have. She was denied the bonus.
The lawsuit also says the TVAAS
estimates are too arbitrary, only using test results of a small segment of a
teacher's students to estimate overall effectiveness.
TEA says it expects this to be the
first of many TVAAS lawsuits across the state.
