In the quest to achieve better academic outcomes for all students, the focus in education has shifted to a model of accountability. The most recent trend in the accountability movement is a focus on the effect of teachers in promoting student achievement. Research has found that teachers have the most significant school level impact on student achievement, and increases in teacher effectiveness could have major implications for the learning outcomes of students across the nation. Much of the current focus in teacher evaluation reform centers on methods through which teachers can be more accurately evaluated based on their contributions to student learning. In the push towards greater accountability for teachers, the development of measures that are both fair for teachers and lead to stronger outcomes for students are critical to seeing long-term improvements in the education system. This report explores variability and stability of value-added measures over time by looking in depth at the methods, assumptions, limitations, and implementation of the most commonly used value-added models across the country and the research about the correlations of these measures over time. This research is followed by a case study of a de-identified large urban school district implementing a teacher evaluation system that uses both a commercially produced value-added measure and an alternative student-growth measure to make high stakes decisions about teacher effectiveness. The findings from this case study show correlations that do not differ significantly from the prior research on the year-to-year variability in teacher value-added measures, but urge for continued evaluation of these measures over time, especially in high-stakes decisions. Ultimately, value-added measures are only as useful as their effectiveness in influencing the core outcomes of teaching and learning, and therefore these measures must be carefully integrated into and validated against holistic assessments of teacher effectiveness in order to truly impact student outcomes. / text

While teacher quality is recognized as a critical component in school reform, and the pursuit of new teacher evaluation systems has gained national attention, the question of whether proposed teacher assessment models meet the needs of special education teachers has gone largely unnoticed. Current efforts to design teacher evaluation processes that accurately distinguish between effective and ineffective teachers must take into account the difficulties of using new, innovative evaluation systems to appraise teachers who serve students with disabilities. Important differences in the roles, expertise, and circumstances in which special education teachers carry out their responsibilities result in challenges related to the use of observation protocols in evaluating instructional practices, obtaining valid measures of student progress, and understanding the relevance of teacher credentials (i.e., degrees earned and certification) in the special education setting. Through this qualitative research dissertation, the researcher sought to gain insight into the perceptions and experiences of special education teachers and administrators to better understand (a) the relationship between teacher evaluation and teacher effectiveness; (b) the ways in which educators approach the challenges of applying teacher evaluation systems for special education teachers; and (c) the ways in which teacher evaluation processes support the professional growth and development of special education teachers. / text

The purpose of this study was to analyze the relationship that exists among instructional practice scores, value-added measures, and learning gains for the Large Urban School District (LUSD) among reading teachers in Grades 6-12 for the 2012-2013 school year. In addition, this study was also conducted to address the perceptions of secondary school principals and assistant principals regarding the relationship of the three variables and their relevance in making personnel decisions. Quantitative data were obtained from school district databases for observation scores, value-added measures, and standardized assessment achievement data to determine the relationship among the variables. In addition, a perception survey was completed by secondary school principals and assistant principals. With a sample size of 138, the survey yielded a return rate of 84%. The data were analyzed to determine actual relationships among instructional practice scores, value-added measures, and learning gains, as well as how the participants perceived each variable in isolation. The literature review supported the findings regarding the inflation of observation scores by school administrators. The only significant relationship (.48) existed between value-added measures and learning gains. Likewise, school leaders in the LUSD believed that their observations were important in analyzing the needs of their teachers and should be included in summative evaluations. Learning gains were supported by the participants more than instructional practice scores and value-added measures as evidence of effective instruction. The literature review revealed past program evaluation studies regarding the Florida Comprehensive Achievement Test (FCAT) as a valid measure for assessing grade level benchmarks. The information in this study is valuable and suggests that continued professional learning for school leaders regarding classroom observations to improve inter-rater reliability is needed. Likewise, school leaders would benefit from understanding the relationships that exist among instructional practice scores, value-added measures, and learning gains to drive conversations with teachers regarding rigorous instruction.
