Instructional leadership has become the dominant paradigm in principal preparation and professional learning. In parallel, teacher evaluation has risen in prominence. Using interviews from 84 principals in 23 districts and three states, we asked how teacher evaluation influenced principals' reported priorities and conceptions of instructional…

Principals can affect several consequential schooling processes and outcomes. However, their effectiveness varies substantially and is distributed across schools inequitably, underscoring the importance of effective principal professional development (PPD), which begins by using needs assessments to inform PPD content. A researcher-practitioner…

Using panel data from three successive collective bargaining (CBA) negotiation cycles from 277 California school districts in a difference-in-differences framework, I investigate the relationship between changes in CBA restrictiveness and racial and economic achievement gaps over time. I find that achievement gaps in California are smaller where…

Teacher evaluation systems often include classroom observations in which raters use rating scales to evaluate teachers' effectiveness. Recently, researchers have promoted the use of multifaceted approaches to investigating reliability using Generalizability theory, instead of rater reliability statistics. Generalizability theory allows analysts to…

Educational policies addressing instruction may fail to acknowledge that effective instruction is not the same for all learners. We reviewed teacher evaluation systems across all states and the 25 largest districts to determine how states and districts approach the evaluation of special education teachers, a policy aimed at improving teaching…

Until recently, legal challenges to the use of value-added models (VAMs) in evaluation and teacher employment decisions in federal court had been unsuccessful. However, in May 2017 a federal court in Texas ruled that plaintiff-teachers established a viable federal constitutional claim to challenge the use of VAMs as a means for their termination…

This study turns a rhetorical lens on the debate about how best to use value-added modeling (VAM) in teacher evaluation by addressing the question, Which arguments legitimize the dismissal of expert caution about proposed education reforms? My rhetorical analysis of a corpus of nonacademic texts (e.g., newspapers, magazines, political speeches)…

Grow Your Own (GYO) programs are designed to recruit high school students, paraeducators, community organizers and parents, and/or career changers from the local community to join the educator workforce. When considering the nontraditional teacher pools that may enter the profession through GYO programs, commonly held assumptions about who…

Raters must score accurately and consistently for classroom observation scores to be valid. This requires (a) a standard defining when scoring is accurate and consistent enough and (b) measuring and remediating rater performance against that standard. Current practice has focused on this second problem to the exclusion of the first. My goal here…

Instructional coaching has emerged as a prevalent and much-lauded instrument for capacity building. This essay argues that coaching can be aligned with teacher evaluation systems to work toward the effective implementation of instructional reforms, including Common Core State Standards and Next Generation Science Standards. Within the current…

This article describes an educational design research program situated within a professional development school that led to the development of the Cultural Proficiency Continuum Q-Sort (CPCQ). The CPCQ is a tool that enables teacher educators to systematically examine preservice teachers' cultural competence concerning students who are…

Although most students with disabilities (SWDs) receive instruction from general education teachers, little empirical work has investigated whether these students have suitable access to high-quality teachers. We explore the differences in teacher quality experienced by SWDs and students without disabilities (non-SWDs) in the Los Angeles Unified…

In this commentary, the author states that, as the contributions of the focal articles make clear, there is much to learn about how value-added models (VAMs) are actually used in a variety of settings. Indeed, it is important to remember that VAM scores are but one component of a complex evaluation system that can play out differently in different…

In recent years, states and districts have responded to federal incentives and pressure to institute major reforms to their teacher evaluation systems. The passage of the Every Student Succeeds Act in 2015 now provides state policymakers with even greater autonomy to redesign existing evaluation systems. Yet, little evidence exists to inform…

The purpose of this statement is to inform those using or considering the use of value-added models (VAM) about their scientific and technical limitations in the evaluation of educators and programs that prepare teachers. The statement briefly reviews the background and current context of using VAM for evaluations, enumerates specific psychometric…
