Elias Walsh specializes in education policy, with a focus on the design and evaluation of value-added measures of educator effectiveness.
Walsh has provided technical assistance to states and districts on developing value-added models to measure teacher and school effectiveness. Currently, he provides support to the Oklahoma State Department of Education on developing value-added measures of educator effectiveness for its educator evaluation system. He has also developed value-added models and examined the relationships between value added and other educator evaluation components for the District of Columbia (DC) and the state of Pennsylvania. He led Mathematica’s effort to evaluate the impact of school reform in DC with the DC Education Consortium for Research and Evaluation. In addition, he directed an investigation of the impact of new principals on student achievement in DC. Walsh has also co-authored many Mathematica reports and working papers, including methodological papers on value-added models.
Before joining Mathematica in 2011, Walsh was a Teach For America math teacher in the Chicago Public Schools. He is a reviewer for Educational Researcher and Economics of Education Review and holds a Ph.D. in economics and public policy from the University of Michigan.
Pennsylvania Teacher and Principal Evaluation Pilot
We examined practices of teachers who make larger contributions to student achievement growth, reviewed plans for an overall effectiveness measure, described variation in professional practice scores, and examined practices strongly correlated with contributions to student achievement growth.
The Impact of Replacing Principals on Student Achievement in DC Public Schools
The Public Education Reform Amendment Act led to numerous reforms that changed nearly every aspect of DC public schools. In this project, we focus on one consequence of the reforms by examining the impact of principal replacements that began in 2007 on student achievement.
Value-Added Analysis Services for the State of Oklahoma
Mathematica is providing support to the Oklahoma State Department of Education on developing value-added measures of educator effectiveness for its educator evaluation system. The system was piloted in the 2013-14 school year with full implementation in the 2015–16 school year.
Impact of 2007 DC School Reforms
As a contributor to the DC Education Consortium for Research and Evaluation, we are providing descriptive statistics about the retention of effective teachers, the distribution of teacher quality across schools and wards, and the experience and tenure of principals.
