q2 · i? · qualitative · r2

Descriptive before-and-after evidence from the case study's culture section: pre-turnaround, "one out of four students were suspended" with roughly 1,200 hours of lost instructional time; the report later notes the school's proudest accomplishments included not suspending a single student.

"In the year prior to turnaround, one out of four students were suspended at Perry Street, losing roughly 1,200 hours of instructional time due to suspensions alone."
