From the Texas Tribune: Teacher Group Sues Over Plan to Tie Evaluations to Tests

Still more on education in Texas - this time one that involves interest groups, the courts and civil law.

A teachers group filed a lawsuit Wednesday in an attempt to block the state from implementing a controversial system that for the first time ties assessments of educators to student performance on standardized tests.
In a lawsuit filed against Texas Education Commissioner Mike Morath in Travis County district court, the Texas State Teachers Association alleges that the new teacher evaluation system — the Texas Teacher Evaluation and Support System, or T-TESS — violates state law by requiring school districts to base 20 percent of each teacher's evaluation on “student growth measures” that include standardized test scores.

Those student growth measures may include “value added measures,” or VAM, which “is typically based on a complicated formula that compares actual student test scores to the scores predicted by a mathematical target based on the standardized test scores of similar student populations,” the association explained in a statement.
“TSTA contends that state law … clearly requires a teacher appraisal system adopted by the commissioner to be based on ‘observable, job-related behavior,’” the statement said. “But a VAM model is not ‘observable’ and is not even available to teachers and others who wish to understand the basis for their evaluations.”
