Description¶
A statewide administrative dataset maintained by the Illinois Community College Board and accessed through the Illinois Longitudinal Data System, containing enrollment, credential, program, and credit records for students at Illinois public two-year colleges.
Components¶
- Illinois Community College Board (ICCB) data via the Illinois Longitudinal Data System: ICCB data, accessed through the ILDS, is a state administrative dataset covering all public two-year colleges in Illinois. The article states that "Students cannot opt out of the data, making it a more comprehensive source of information on CPS graduates who enroll in two-year colleges than NSC data." It classifies credentials as associate degrees, short-term certificates, or long-term certificates, and includes program types, credits attempted and earned, and early college enrollment. Records link across state agencies via the CDDA ID without transferring personal identifying information. (Jenny Nagaoka et al. (2020))
Claims¶
- Linking CPS, ISBE, and ICCB records through the CDDA ID matched 97 percent of the 2012 CPS graduating class to ICCB data [+W]
- NSC data cannot be used alone to calculate two-year credential-type completion rates because 57.5 percent of completion records have a blank credential name field [+W]
- Full-time immediate two-year enrollment rates differ substantially between ICCB and NSC data, suggesting limited reliability of the NSC full-time status field [+W]
- NSC and ICCB data agree on any-credential completion within four years for 96 percent of immediate two-year enrollees [+W]
- NSC and ICCB data agree on immediate two-year college enrollment for about 96 percent of students, with ICCB showing a slightly higher enrollment rate [+W]
