Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? ICCB data showed immediate two-year enrollment for 21.9 percent of 2012 CPS graduates versus 20.5 percent in NSC data, and the two datasets matched on enrollment outcome for around 96 percent of students. → Jenny Nagaoka and Shelby Mahaffie 2020

q2 · i? · associational · r2
Student-level alignment analysis of immediate two-year enrollment for 19,209 2012 CPS graduates with records in both datasets. The datasets agreed for about 96 percent of students; 274 students (1.4 percent) had enrollment in NSC only and 553 (2.9 percent) in ICCB only.
"While the ICCB data showed an immediate enrollment for 21.9 percent of the students, the NSC data showed an immediate enrollment for only 20.5 percent of the students."
Discussion¶
Related Claims¶
- Linking CPS, ISBE, and ICCB records through the CDDA ID matched 97 percent of the 2012 CPS graduating class to ICCB data — related
- 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 — related
- Full-time immediate two-year enrollment rates differ substantially between ICCB and NSC data, suggesting limited reliability of the NSC full-time status field — related
- NSC and ICCB data agree on any-credential completion within four years for 96 percent of immediate two-year enrollees — related
