Summary of simulation findings: raising cumulative GPA by 0.4 points closes nearly half the CPS-national graduation gap and exceeds the effect of raising ACT scores for all students.

"Increasing GPA by 0.4 points makes up almost one-half of the difference between the CPS and national four-year college graduation rates, and has a larger impact on college graduation than increasing ACT scores for all students."

Related Claims¶

• Almost one-half of between-school differences in college graduation rates among similarly-qualified CPS students is attributable to the colleges to which high schools send their students — related
• CPS graduates' academic qualifications improved steadily from 2003 to 2015, with districtwide ACT rising from 16.97 to 18.81 and GPA from 2.16 to 2.56 — related
• Graduates' academic qualifications improved alongside graduation rates, with ACT scores rising from 16.7 to 18.6 between 2003 and 2014 — related
• Evidence on RJ's impact on academic outcomes is limited and mixed, with graduation-rate gains in one study and no GPA change in another — related
• Four-year college graduation rates rose from 56.0 to 59.4 percent between 2003 and 2013, with larger gains at public institutions (4.9 points) than private nonprofits (2.3 points) — related
• HSGPA has a strong, positive relationship with college graduation that does not vary significantly in its linear slope across high schools — related
• Only CPS graduates with access to very selective colleges (above 3.3 GPA and ACT 26+) have four-year college graduation prospects exceeding 50 percent — related
