q1 i? The report's method compares dropouts to all eighth-grade graduates and allows five years to graduate, so its systemwide percentages are somewhat smaller than CPS's. → Shazia Rafiullah Miller 1999

Shazia Rafiullah Miller, Stuart Luppescu, Robert M. Gladden, John Q. Easton. (1999). How Do Barton Graduates Perform in CPS High Schools? Consortium on Chicago School Research. https://consortium.uchicago.edu/publications/how-do-barton-graduates-perform-cps-high-schools

q1 · i? · associational · r1

Methodological statement in the report's introduction explaining that it uses a baseline of all students graduating from eighth grade (including those who left CPS) and allows five years to graduate, whereas the board compares dropouts only to graduates and allows four years. No effect size applies.

"Therefore, our cal- culations of the percent of dropouts and graduates in the school system are some- what smaller than CPS’s numbers."
