Ongoing or recently completed across the United States are a series of lawsuits via which teacher plaintiffs are contesting how they are being evaluated using value-added models (VAMs) as part of states'/districts' teacher accountability systems. To investigate the empirical and pragmatic matters addressed in court, researchers conducted a case…

Contemporary teacher evaluation policies are built upon multiple-measure systems including, primarily, teacher-level value-added and observational estimates. However, researchers have not yet investigated how using these indicators to evaluate teachers might distort validity, especially when one indicator seemingly trumps, or is trusted over the…

Recent lawsuits reveal common mistakes plaguing current teacher evaluation systems. Drawing on arguments in court documents for prominent cases, the authors find that evaluation systems using value-added measures (VAM) suffer from a) inconsistent and unreliable teacher ratings, b) bias toward and against teachers of certain types of students, c)…

For this study, researchers critically reviewed documents pertaining to the highest profile of the 15 teacher evaluation lawsuits that occurred throughout the U.S. as pertaining to the use of student test scores to evaluate teachers. In New Mexico, teacher plaintiffs contested how they were being evaluated and held accountable using a homegrown…

The Every Students Succeeds Act (ESSA) loosened the federal policy grip over states' teacher accountability systems. We present information, collected via surveys sent to state department of education personnel, about all states' teacher evaluation systems post-ESSA, while also highlighting differences before and after ESSA. We found that states…

Researchers explored how 13 states in which policymakers have adopted an A-F school letter grade accountability system performed on the National Assessment of Educational Progress (NAEP) post-policy implementation. Researchers found mixed results, with approximately half of these 13 states increasing achievement post-policy, and the other…

Contemporary teacher evaluation systems are built upon multiple measures including, primarily, teacher-level value-added and observational estimates. While researchers have conducted examinations of these systems and indicators, researchers have not investigated how using these systems might distort the validity of the inferences being drawn,…

In "Houston Federation of Teachers (Plaintiff) v. Houston Independent School District (Defendant)," plaintiffs contested how teachers were being evaluated using a value-added model (VAM) as part of the districts' teacher accountability system. The VAM at issue was the Education Value-Added Assessment System (EVAAS), with potential…

In this study researchers examined the effectiveness of one of the largest teacher education programs located within the largest research-intensive universities within the US. They did this using a value-added model as per current federal educational policy imperatives to assess the measurable effects of teacher education programs on their teacher…

Despite the concerns regarding value-added models (VAMs), advocates hold strong to VAMs' theoretical strengths and potentials, while adopting a set of agreed-upon albeit "heroic" set of assumptions, without research in support. These assumptions transcend promotional, policy, media, and research-based pieces, but they have never been…

Federally mandated standardized testing (i.e., in core subject areas and certain grade levels), as an element of educational accountability, began in 2002 with the No Child Left Behind Act. With that step, large-scale assessments came to serve as one of the foundations of accountability-based systems and policies not only for districts, schools…

Purpose: The purpose of this document analysis study was to examine current teacher evaluation systems, understand current practices, and determine whether the instrumentation is a valid measure of teaching quality as reflected in teacher behavior and effectiveness specific to physical education (PE). Method: An interpretive document analysis…

In this study, we investigated the factor structure underlying the TAP System for Teacher and Student Advancement used across the nation for increased teacher-level accountability purposes. We found evidence of poor fit based on the factor structure posited and found large correlations among dimensions, suggesting one-to-two factors with one…

Being an expert involves explaining how things are supposed to work, and, perhaps more important, why things might not work as supposed. In this study, researchers surveyed scholars with expertise in value-added models (VAMs) to solicit their opinions about the uses and potential of VAMs for teacher-level accountability purposes (for example, in…

Given changes to the ways teachers and, by association, the universities that prepare them are held accountable, the critical work of John Goodlad in educational renewal through teacher education has restored at least some capacity to reframe conversations about ways to better prepare teachers to serve diverse students in America's schools. In…
