Discussion¶
Related Claims¶
- Peer outcomes following a district suspension reform varied with school-level implementation — related
- Many Philadelphia schools did not comply with the policy change prohibiting out-of-school suspension for low-level offenses — a narrower finding that bears on this claim
- In schools that did not fully implement the district-level suspension reform, peer math achievement declined and attendance decreased — a narrower finding that bears on this claim
