What is GBEN?

The Greater Boston Evaluation Network (GBEN) is a collective of evaluators and other professionals doing evaluation-related work in and around the Greater Boston, Massachusetts, region. We are an official local affiliate of the American Evaluation Association. 

We have members who represent disciplines including K-12 Education, Public Health, Social and Economic Policy, and Government and Public Sector Services. We are a strong mix of nonprofit professionals, internal and external evaluators, self-employed evaluation consultants, researchers, and university students. Our members have experience ranging from "just getting started" to over 20 years in the field!

Each year, GBEN hosts regular "Roundtable" meetings to share best practices, resources, and problems of practice in a range of evaluation and data topics. GBEN also hosts quarterly social events and is looking to expand programming to include more events to meet the needs of members.
