About Ed Impact Lab

Mathematica established the Educator Impact Laboratory in 2016 to expand our collaborations with state and local education agencies around the challenging task of measuring the impact that teachers, principals, and schools have on their students and using this information to improve outcomes. The lab’s expert team of staff and affiliates is committed to supporting education leaders in this work by sharing resources like free value added code and evaluation tools, writing blog posts and publications on the latest policy issues and research, and working directly with agencies through our offerings.
