Research & Evaluation

You have questions. DSG gets the answers.

In keeping with our mission of Science in the Service of People, the dozens of scientists and support staff who make up DSG’s Research and Evaluation Division help clients and consumers alike make evidence-based decisions about behavioral health, justice, and education policies, programs, practices, and interventions.
