About Ed Impact Lab

For more than two decades, Mathematica has worked with education leaders at the federal, state, and local levels to measure the performance of teachers, examine the distribution of effective teaching, and understand the factors that help educators have a greater impact on the students they serve. Some research has been done on a large scale, through national evaluations and other multisite studies, but the work of educators happens at the local level. In our one-on-one collaborations with state and local education agencies, we see that many districts have similar needs for rigorous evidence but limited capacity for original research and no desire to reinvent the wheel.

Mathematica established the Educator Impact Laboratory in 2016 to expand our collaborations with state and local education agencies—and leading academic researchers—in which we develop and apply innovative methods and tools to estimate the impacts that educators have on their students. The Ed Impact Lab builds on this work measuring educator impact by translating findings into context, to ensure that education leaders can use those findings to improve education.

The Educator Impact Laboratory equips education leaders to make better decisions by:

Demystifying the statistics behind using value-added and student growth models as part of teacher evaluations

Creating interactive data visualization tools to support real-life decision-making

Weighing in on important debates through a blog about education concepts related to standardized testing, use of test scores to measure teacher and principal performance, and research methods

Building a network of academic affiliates representing the most cutting edge research on educator impact

Convening events to present research, working papers, and academic publications

Sharing data analytic tools, including a repository of free, open-source programmer code for statistical analysis
