Knox County TVAAS Lawsuit and the 14th Amendment

Interesting developments in Knox County, where the TEA is bringing a lawsuit against the state regarding TVAAS data.  They claim that the system of evaluating teachers on TVAAS violates the 14th amendment of the US Constitution and should be thrown out.  From the Tennessee Ed Report:

The Tennessee Education Association (TEA) has filed a lawsuit on behalf of a Knox County teacher who was denied a bonus under that school system’s pay plan after Tennessee Value-Added Assessment System (TVAAS) data for 10 of her students was unknowingly attributed to her.

TVAAS is Tennessee’s system of measuring student growth over time. It generates data based on student test scores on TCAP and end of course tests.

In this specific case, the teacher, Lisa Trout, was assigned TVAAS data for 10 students after being told her evaluation would be based on system-wide TVAAS data because she taught at an alternative school.

The TEA lawsuit cites two different memos which indicated that Ms. Trout could expect an evaluation (and bonus eligibility) to be based on system-wide data. At the conclusion of the school year, Ms. Trout was informed that her overall evaluation score, including observations and TVAAS data was a 4, making her eligible for a bonus under the Knox County pay plan.

When she did not receive the bonus as expected, she began asking questions about why the bonus had not been paid.  She ultimately determined that without her knowledge, a school counselor had assigned 10 students to Ms. Trout for the factoring of TVAAS scores.  The students were in an Algebra II course Ms. Trout taught, even though she does not hold an endorsement for teaching Alegbra II.

I am not a legal scholar, but it will be interesting to watch this as it progresses through the courts as it could have profound implications for how data is used in teacher evaluations in Shelby County, Tennessee and across the country.
