This brief describes the experiences of Ohio as a state partner of the Coleridge Initiative. The Coleridge Initiative is a nonprofit organization that collaborates with federal, state, and local government agencies to build capacity to improve research and policy by providing a platform to securely link confidential microdata within and across states and agencies, and by offering training classes to agency staff. This is the first of three briefs on the experiences of the Coleridge Initiative and its partners. Ohio was one of the Coleridge Initiative’s early state partners, and one of the most important benefits of training was the relationships it established across agencies within Ohio and with other states. Using the Coleridge Initiative’s secure microdata linking platform, Ohio has collaborated with neighboring states to understand labor market outcomes for its college graduates who move out of state.
