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? 17.6 percent of students attempted at least 12 credit hours in fall 2012 per ICCB records, while NSC data contained full-time enrollment for only 12.9 percent of students. → Jenny Nagaoka and Shelby Mahaffie 2020

q2 · i? · associational · r2
Alignment analysis of full-time immediate two-year enrollment definitions between ICCB (at least twelve credit hours attempted) and NSC (college-reported full-time status) for the same 19,209-student cohort. The authors suggest full-time status "is being determined at different points in the term in the two different datasets."
"There was a larger difference between the full-time immediate enrollment rates: 17.6 percent of students attempted at least 12 credit hours in the fall 2012 according to their ICCB records, while the NSC data contained full-time enrollment for only 12.9 percent of the students."
Discussion¶
Related Claims¶
- NSC and ICCB data agree on any-credential completion within four years for 96 percent of immediate two-year enrollees — related
- 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 — 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
- Linking CPS, ISBE, and ICCB records through the CDDA ID matched 97 percent of the 2012 CPS graduating class to ICCB data — related
