q2 · i? · causal · r?

The report's summary reports positive effects on "probability of graduating" as part of the same finding covering ACT scores and college entry. This is described as the first report to examine charter effects on long-term attainment including high-school graduation. No effect sizes are printed.

"The authors find that Chicago's multi-grade charter high schools (those that include grades 6-12, 7-12, or K-12) appear to produce substantial positive effects on ACT scores, probability of graduating, and probability of enrolling in college."
