Introducing the program
Home of the Statewide Longitudinal Data System
The Oregon Longitudinal Data Collaborative (OLDC) links data about students as they move through school and the workforce. The purpose of the OLDC is to provide actionable data-supported policy recommendations that impact student learning, training, and workforce opportunities.
Longitudinal data allows policy makers to clearly identify outcomes of programs across student populations and geographic regions. This helps the state pinpoint and address areas of inequities so it can better direct resources and funding to programs that are helping students succeed. OLDC manages Oregon’s Statewide Longitudinal Data System (SLDS) which brings together data from K-12, Postsecondary, and Workforce.
Learn more about our data sources
OLDC is a collaboration governed by the state agencies who provide data,
including the Higher Education Coordinating Commission, Oregon Department of
Education, the Oregon Employment Department, and Teacher Standards and
Practices Commission. These data partner agencies determine what data is provided to the OLDC, what reports and research studies OLDC will use the data for, and how that data is securely stored and used. The OLDC partner agencies collect student data and the OLDC staff, housed in the Higher Education Coordinating Commission (HECC), act as a central hub where the data can be linked and analyzed. The OLDC conducts studies and provide data reports to state agencies based upon the research agenda, a plan developed annually.
Learn about how we protect your data
The OLDC works with the data partner agencies to ensure that the student and individual-level data is secured in the system and used appropriately. The Statewide Longitudinal Data System (SLDS), which houses all of the data, is secured by the state’s data center, follows agency-identified policies and protocols to utilize the data safely, and follows best practices in data security and privacy. In addition, every project that OLDC undertakes is reviewed and approved by a governance committee which is made up of representatives from data partner agencies, and the results are reviewed prior to publication.
