Research

​​Featured Reports of the Oregon Longitudinal Data Collaborative 

Each year, OLDC engages in a variety of data reporting and research projects as determined by the research agenda. Below is a summary of recent public reports and research. OLDC also provides matched data to the agencies for their own reporting and research needs.

Reports and Research from the 2021-22 Research Ag​enda​

SLDS Overview   

Description: This high-level look at the data to show the number of records, data connections, and the overlap between the data sources. 

Report Type: Infographic with descriptive statistics.

Goal: Inform about the data sources available in Statewide Longitudinal Data System (SLDS). 

Reporting Limitations: This report provides the counts of records from each data source and the number of connections found between the data sources. The SLDS does not receive wage data from jobs that do not report unemployment insurance, such as self-employed or contracted positions.


Educational Pathways in Oregon   

Description: This report follows the pathway of students who entered high school in 2006-07 and looks at their postsecondary and workforce outcomes. This report looks at K-12 student outcomes and sets some initial benchmarks for postsecondary enrollment, achievement, and workforce participation. 

Report Type: Infographic with descriptive statistics. 

Goal: Provide high-level metrics to demonstrate the capabilities of the SLDS for policy makers and the public in order to identify areas of interest for future studies.

Key Notes for Interpretation:
  • The outcomes and metrics in this report include data through 2019 at which point students were approximately 27 years old. 
  • In the “High school students in this report include” section, there was a change in the 2013-14 school year to how ODE calculates graduation data. All numbers are within 1% of ODE’s published numbers.
  • In the first section, “High school students in this report include”, the number of students that Did not complete is at 21 percent. However, the “Highest Credential Earned” shows 20 percent does not have any credential.  The difference is the number of individuals who earned their diploma or equivalent after 7 years of entering high school, which is beyond the reporting window. 
  • For wage data, the median (the ordered middle) is used instead of the mean (an average) because the upper and lower ends of data skew the average. 
  • The wage data is calculated per individual, not per family. 
  • The ‘Years in workforce’ data is the approximate years students could be in the workforce factoring in the average length of time each credentials takes to earn.
Reporting Limitations: 
  • In the “Highest Credential Earned” section, the total does not equal 100 percent because of rounding. 
  • The SLDS does not receive wage data from jobs that do not report unemployment insurance, such as self-employed or contracted positions.​
