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.

Methodological analysis in the report's introduction comparing rate-calculation approaches. The brief states the ISBE method "overestimates the graduation rate" where transfers are frequent; the report's cohort method is presented as producing the actual rate the ISBE method intends to estimate.
"the method used by the Illinois State Board of Education (ISBE) overestimates the graduation rate when large numbers of students transfer between schools, as is the case in Chicago"
Discussion¶
Related Claims¶
- Graduation rates differ largely across Chicago schools, with many new charter and magnet schools and several neighborhood high schools showing exceptionally high rates beyond what incoming freshman characteristics would predict — related
- CPS graduation rates increased by 22.4 percentage points over 16 years, from 52.4 percent among students who turned 19 in 1998 to 74.8 percent in 2014 — related
- The report's dropout and graduate percentages are calculated differently from CPS's and are therefore somewhat smaller than CPS numbers — related
- Over 40 percent of Chicago Public Schools students drop out by age 19, with a slight downward trend across the 1991–1994 cohorts — related
