From the press release:
Certificate recipients in Oregon ages 29 or younger reap sizable earnings gains, in some cases more than doubling their pay, as they build their skills and enter the workforce, according to a new analysis of community college programs in the state. The Georgetown University Center on Education and the Workforce (Georgetown Center) report, Certificates in Oregon: A Model for Workers to Jump-Start or Reboot Careers, highlights the role of certificates for people seeking to enter the labor market, an issue that has drawn increasing attention from policymakers in Washington, DC and across the nation.
The new analysis is based on state-level data that sheds light on their labor market value by field of study and their impact on both college-age students entering the labor market and adults established in the workforce. It also shows the importance of major national and state investments in data systems that have allowed states like Oregon to track the earnings returns of particular credentials.
