Value-added modeling (VAM) to estimate school and teacher effects is currently of considerable interest to researchers and policymakers. Recent reports suggest that VAM demonstrates the importance of teachers as a source of variance in student outcomes. Policymakers see VAM as a possible component of education reform through improved teacher evaluations or as part of test-based accountability. They are intrigued by VAM because of the view that its complex statistical techniques can provide estimates of the effects of teachers and schools that are not distorted by the powerful effects of such noneducational factors as family background. This monograph clarifies the primary questions raised by the use of VAM for measuring teacher effects, reviews the most important recent applications of VAM, and discusses a variety of statistical and measurement issues that might affect the validity of VAM inferences. The authors identify numerous possible sources of error and bias in teacher effects and recommend a number of steps for future research into these potential errors. They conclude that the research base is currently insufficient to support the use of VAM for high-stakes decisions about individual teachers or schools. It is important that policymakers, practitioners, and VAM researchers work together, so that research is informed by the practical needs and constraints facing users of VAM and that implementation of the models is informed by an understanding of what inferences and decisions the research currently supports.

Value-added models are complex statistical formulas that aim to isolate the effect a teacher has on student learning. States and districts across the nation are adopting laws and policies that will evaluate teachers, in part, using the results provided by value-added models. In many states and districts, these evaluations will be used to inform high-stakes decisions about teacher salary and retention. However, value-added models are imperfect tools for assessing teacher effectiveness, and many scholars have argued that they are not appropriate for use in high-stakes decisions. This Article provides a brief history of the use of value-added models in public education and summarizes the major criticisms of using value-added models. In this context, the Article analyzes and evaluates the extent to which substantive due process claims brought by teachers adversely affected by the results of value-added models will be successful. The Article concludes that while the system as a whole is rationally related to the objective of improving the overall effectiveness of the teaching workforce, in certain cases, individual teachers will be able to successfully claim that the results of their value-added model led to a termination that was arbitrary and capricious. Finally, the paper offers some recommendations to states and school districts on how to implement an evaluation system using value-added models to avoid substantive due process violations.

Value-added methods refer to efforts to estimate the relative contributions of specific teachers, schools, or programs to student test performance. In recent years, these methods have attracted considerable attention because of their potential applicability for educational accountability, teacher pay-for-performance systems, school and teacher improvement, program evaluation, and research. Value-added methods involve complex statistical models applied to test data of varying quality. Accordingly, there are many technical challenges to ascertaining the degree to which the output of these models provides the desired estimates. Despite a substantial amount of research over the last decade and a half, overcoming these challenges has proven to be very difficult, and many questions remain unanswered--at a time when there is strong interest in implementing value-added models in a variety of settings. The National Research Council and the National Academy of Education held a workshop, summarized in this volume, to help identify areas of emerging consensus and areas of disagreement regarding appropriate uses of value-added methods, in an effort to provide research-based guidance to policy makers who are facing decisions about whether to proceed in this direction.

Modeling student growth has been a federal policy requirement under No Child Left Behind (NCLB). In addition to tracking student growth, the latest Race To The Top (RTTP) federal education policy stipulates the evaluation of teacher effectiveness from the perspective of added value that teachers contribute to student learning and growth. Student growth modeling and teacher valueadded modeling are complex. The complexity stems, in part, from issues due to nonrandom assignment of students into classes and schools, measurement error in students’ achievement scores that are utilized to evaluate the added value of teachers, multidimensionality of the measured construct across multiple grades, and the inclusion of covariates. National experts at the Twelfth Annual Maryland Assessment Research Center’s Conference on “Value Added Modeling and Growth Modeling with Particular Application to Teacher and School Effectiveness” present the latest developments and methods to tackle these issues. This book includes chapters based on these conference presentations. Further, the book provides some answers to questions such as what makes a good growth model? What criteria should be used in evaluating growth models? How should outputs from growth models be utilized? How auxiliary teacher information could be utilized to improve value added? How multiple sources of student information could be accumulated to estimate teacher effectiveness? Whether studentlevel and schoollevel covariates should be included? And what are the impacts of the potential heterogeneity of teacher effects across students of different aptitudes or other differing characteristics on growth modeling and teacher evaluation? Overall, this book addresses reliability and validity issues in growth modeling and value added modeling and presents the latest development in this area. In addition, some persistent issues have been approached from a new perspective. This edited volume provides a very good source of information related to the current explorations in student growth and teacher effectiveness evaluation.

Since passage of the of No Child Left Behind Act in 2001, academic researchers, econometricians, and statisticians have been exploring various analytical methods of documenting students‘ academic progress over time. Known as value-added models (VAMs), these methods are meant to measure the value a teacher or school adds to student learning from one year to the next. To date, however, there is very little evidence to support the trustworthiness of these models. What is becoming increasingly evident, yet often ignored mainly by policymakers, is that VAMs are 1) unreliable, 2) invalid, 3) nontransparent, 4) unfair, 5) fraught with measurement errors and 6) being inappropriately used to make consequential decisions regarding such things as teacher pay, retention, and termination. Unfortunately, their unintended consequences are not fully recognized at this point either. Given such, the timeliness of this well-researched and thoughtful book cannot be overstated. This book sheds important light on the debate surrounding VAMs and thereby offers states and practitioners a highly important resource from which they can move forward in more research-based ways.

"This book is an in-depth examination of the growing alignment between powerful global bioindustries and education reform in the U.S. Utilizing a biopolitical methodology, the book focuses on how value-added measures and other neoliberal strategies embedded in policies such as 'race to the top' are involving schools in a project to manage and regulate educational life for competing in a new 'flat world'. Understanding the educational present, this work argues, requires individuals to consider what advanced industrialized nations across the globe are viewing as the future. Biocapitalist development in areas such as genetic engineering, drug therapies, and cellular cloning is the promissory future driving nations like the U.S. to out-compete and out-educate one another at any cost. This book assesses the implications for education in the biocapitalist era and points to alternative futures not based on such a vision of life and its productive potential"--
