Panel or grouped data are often used to allow for unobserved individual heterogeneity in econometric models via fixed effects. In this paper, we discuss identification of a panel data model in which the unobserved heterogeneity both enters additively and interacts with treatment variables. We present identification and estimation methods for…

This action research study examined the relationship between teacher performance and student achievement in reading language arts and mathematics. The study sought to determine if teacher evaluation methods used to determine teacher performance, had a relationship in improving student achievement. The researcher investigated the topic using…

This publication summarizes the key discussion from experts in the field of measuring student growth during a convening held February 2015. Experts heard about two emerging approaches to measuring growth: Portfolios of student work samples and unit value-added models that provide teachers with timely and actionable feedback that they can use to…

In response to the recession that began in 2007, the U.S. Congress passed, and President Barack Obama signed into law, the American Recovery and Reinvestment Act of 2009 (Pub. Law 111-5). At an estimated cost of $831 billion, this economic stimulus package sought to save and create jobs, provide temporary relief to those adversely affected by the…

In a provocative and influential paper, Jesse Rothstein (2010) finds that standard value-added models (VAMs) suggest implausible future teacher effects on past student achievement, a finding that obviously cannot be viewed as causal. This is the basis of a falsification test (the Rothstein falsification test) that appears to indicate bias in VAM…

There is currently little consensus on how special education teachers should be evaluated in a way that is effective, fair and responsive to their unique teaching responsibilities. In this paper, we explain several of the current approaches to teacher evaluation under consideration, and then provide an overview of the challenges associated with…

Policymakers appear increasingly inclined to utilize measures of student achievement, often state assessment results, to inform high-stakes teacher personnel decisions. This has been spurred on by the federal government's Teacher Incentive Fund (TIF) and Race to the Top (RttT) grant programs, each of which urge states and localities to tie teacher…

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)…
