Effective teachers have an enormous impact on the lives of their students. Great teachers can help students who are behind academically catch up to grade-level expectations. By accelerating student performance, they can help close the opportunity and achievement gaps that cut short the college and career dreams of so many low-income students and…

At the request of Pittsburgh Public Schools (PPS) and the Pittsburgh Federation of Teachers (PFT), Mathematica is developing value-added models (VAMs) that aim to estimate the contributions of individual teachers, teams of teachers, and schools to the achievement growth of their students. The analyses described in this report are intended as an…

Teacher preparation programs (TPPs) are where prospective teachers gain a foundation of knowledge about pedagogy and subject matter, as well as early exposure to practical classroom experience. Although competence in teaching, as in all professions, is shaped significantly by on-the-job experiences and continuous learning, the programs that…

This report describes the value-added models used as part of teacher evaluation systems in the District of Columbia Public Schools (DCPS) and in eligible DC charter schools participating in "Race to the Top." The authors estimated: (1) teacher effectiveness in DCPS and eligible DC charter schools during the 2011-2012 school year; and (2)…

One of the most important things school systems can do to promote student achievement is to ensure that all students have effective teachers. Effective teachers may be particularly important for the most disadvantaged students. The U.S. Department of Education commissioned the American Institutes for Research (AIR) to create this report as a…

The Louisiana Board of Regents is currently outpacing the nation in its ability to inform the public about the effectiveness of redesigned teacher preparation programs in preparing new teachers to teach grades 4-9 students in the areas of mathematics, science, social studies, reading, and language arts. Through the use of Louisiana's Value-Added…

There is often confusion about distinctions between growth models and value-added models. The first half of this paper attempts to dispel some of these confusions by clarifying terminology and illustrating by example how the results from a large-scale assessment can and will be used to make inferences about student growth and the value-added…

In this report, the authors describe the value-added models used as part of teacher evaluation systems in the District of Columbia Public Schools (DCPS) and in eligible DC charter schools participating in Race to the Top. They estimated (1) teacher effectiveness in DCPS and eligible DC charter schools during the 2011-2012 school year; and (2)…

The WAC director, composition director, director of Institutional Assessment (OIA), and WAC/OIA liaison describe the programmatic "needs" and "wants" they balanced in the plan they collaboratively designed to respond to a state mandate for "value-added" writing assessment. To satisfy this mandate, as they explain,…

This paper reports on a study conducted to investigate the consistency of the results between 2 approaches to estimating school effectiveness through value-added modeling. Estimates of school effects from the layered model employing item response theory (IRT) scaled data are compared to estimates derived from a discrete growth model based on the…

The Secretary of Education's Commission on the Future of Higher Education emphasizes accountability in higher education as one of the key areas of interest. The Voluntary System of Accountability (VSA) was developed to evaluate the effectiveness of general public college education. This study examines how student progress in college, indicated by…

Higher education in Louisiana is leading the nation in linking growth of student learning to teacher preparation programs that prepare new teachers. The Louisiana Board of Regents is currently implementing a Value Added Teacher Preparation Assessment. The model examines the degree to which the educational attainment of students taught by recent…

The Louisiana Board of Regents is the first in the nation to publicly use a performance model based upon the achievement of students in grades 4-9 as one of several measures to examine the effectiveness of teacher preparation programs. The State has supported the development and implementation of a Value Added Teacher Preparation Assessment Model…

This study examined the value added to standard textbook-based instruction of plant biodiversity by the use of the exemplary interactive CD-ROM, "Conserving Earth's Biodiversity." This CD-ROM features renowned conservation figure E.O. Wilson. The setting of the research was an introductory biology course in a rural public community…

This study uses the state report cards published by the Tennessee Department of Education to compare the academic achievement grades to the value-added grades to determine if there is a relationship between the two grading systems. The data used for this study are from the 2001, 2002, and the 2003 state report cards published for each school using…
