Over the past 20 years in the United States (U.S.), teachers have seen a marked shift in how teacher evaluation policies govern the evaluation of their performance. Spurred by federal mandates, teachers have been increasingly held accountable for their students' academic achievement, most notably through the use of value-added models (VAMs)-a statistically complex tool that aims to isolate and then quantify the effect of teachers on their students' achievement. This increased focus on accountability ultimately resulted in numerous lawsuits across the U.S. where teachers protested what they felt were unfair evaluations informed by invalid, unreliable, and biased measures-most notably VAMs. While New Mexico's teacher evaluation system was labeled as a "gold standard" due to its purported ability to objectively and accurately differentiate between effective and ineffective teachers, in 2015, teachers filed suit contesting the fairness and accuracy of their evaluations. Amrein-Beardsley and Geiger's (revise and resubmit) initial analyses of the state's teacher evaluation data revealed that the four individual measures comprising teachers' overall evaluation scores showed evidence of bias, and specifically, teachers who taught in schools with different student body compositions (e.g., special education students, poorer students, gifted students) had significantly different scores than their peers. The purpose of this study was to expand upon these prior analyses by investigating whether those conclusions still held true when controlling for a variety of confounding factors at the school, class, and teacher levels, as such covariates were not included in prior analyses. Results from multiple linear regression analyses indicated that, overall, the measures used to inform New Mexico teachers' overall evaluation scores still showed evidence of bias by school-level student demographic factors, with VAMs potentially being the most susceptible and classroom observations being the least. This study is especially unique given the juxtaposition of such a highly touted evaluation system also being one where teachers contested its constitutionality. Study findings are important for all education stakeholders to consider, especially as teacher evaluation systems and related policies continue to be transformed.
