AERA Statement on Use of Value-Added Models (VAM) for the Evaluation of Educators and Educator Preparation Programs
Educational Researcher, v44 n8 p448-452 Nov 2015
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 problems with VAM, and addresses the validity of inferences from VAM, given the challenges of isolating the contributions of teachers and school leaders from the many other factors that shape student learning. The statement also addresses the limitations of using VAM to evaluate educator preparation programs, given the wide variation of experiences and settings in which graduates from those programs work and the lack of comparable and complete information on programs. In addition, the statement goes beyond a consideration of challenges and limitations by specifying eight technical requirements that must be met for the use of VAM to be accurate, reliable, and valid. The statement concludes by stressing the importance of any educator evaluation system meeting the highest standards of practice in statistics and measurement. It calls for substantial investment in research on VAM and alternative methods and models, and cautions against VAM being used to have a high-stakes, dispositive weight in evaluations. [This statement was Approved by AERA Council, June 2015.]
