The research does not necessarily reflect the views of ACT.  \nWill Courts Shape Value-Added Methods for Teacher Evaluation?  \nAbstract: As more states begin to adopt teacher evaluation systems based on value-added measures, legal challenges have been filed both seeing to limit the use of value-added measures (Cook v. Stewart) and others seeking to require more robust evaluation systems (Vergara v. California) . This study reviews existing teacher evaluation systems and examines validity evidence supporting the use value-added scores as part of the teacher evaluation. We discuss key aspects of ongoing teacher evaluation lawsuits in California and Florida and assess issues for evaluating the legality of teacher evaluation systems.  \nKeywords: teacher value-added, legal issues in education, teacher evaluation  \nIntroduction  \nTeacher evaluation has traditionally relied on occasional, brief classroom observations by school principals or other administrators. Nearly all teachers received the highest ranking, irrespective of the academic progress of their students (Weisberg et al., 2009) . In the past decade, researchers have pioneered so-called value-added assessment methods that delineate teacher effectiveness in terms of their success at improving student academic outcomes in their classroom for one grade to the next (Rivkin, Hanushek, and Kain, 2005; Gordon, Kane, and Staiger, 2006; Harris and Sass, 2006; Aaronson, Barrow, and Sander, 2007; Clotfelter, Ladd, Vigdor, 2007; Koedel and Betts, 2007; Jacob and Lefgren, 2008; Kane and Staiger, 2008; Kane, Rockoff, and Staiger, 2008; Buddin and Zamarro, 2009; McCaffrey, Sass, Lockwood, and Mihaly, 2009; Kane, McCaffrey, Miller, and Staiger, 2013) . These studies have found large variation in teacher effectiveness using value-added assessment methods and have suggested that teacher quality could be enhanced by using value-added scores as an element of teacher evaluation. However, the use of teacher value-added measures in personnel decisions remains contentious. Opponents argue that the scores from student achievement tests were not designed to measure teacher performance and the chance of misclassification is too great (Rothstein, et al., 2010) . Proponents contend that misclassification is no greater than in other professions and that value-added methods are better able to differentiate among teachers than existing measures (Glazerman, et al., 2010; Goldhaber & Loeb, 2013) .  \nThe U.S. Department of Education (U.S. DOE) has sided with the proponents, and through the Race to the Top competition and the ESEA Flexibility Waiver program has prompted states to  \nuse teacher value-added methods as a portion of teacher evaluation systems. According to the ESEA Flexibility timeline, nearly half of states plan to begin using teacher evaluation systems that include teacher value-added methods to inform their personnel decisions (13 states in 2014- 2015, 9 states in 2015-2016, and 2 states in 2016-2017) (U.S. Department of Education, 2013) . Most recently, Secretary Duncan announced that states may delay implementation until no later than 2016-2017 so that states have more time to implement college readiness standards and incorporate data from implementation of these standards into the value-added assessments. Thus, the majority of states will be using some type of teacher value-added methodology in personnel decisions in the next few years. The efficacy of these reforms will depend on the ability of states and district agencies to design and implement new and complex management systems that incorporate value-added assessments of teachers.  \nWithin this context, the legality of such systems is an important conside","cbCaim6rXD7dYt4s","https://ap.wps.com/l/cbCaim6rXD7dYt4s","pdf",529321,25,"English","# Abstract\n# Introduction\n## Background on teacher evaluation systems\n## Value-added assessment methods\n## Legal challenges: Cook v.
