Not every statistic is collected every year — each row shows its most recent available school year (amber when older than 2024–25). Blank/absent means not collected or below reliability floors, never zero. Some universal-meals states no longer report free/reduced-price lunch — school poverty (MEPS) is the better lens there. A 0% charter share in a state without a charter-school law is a true zero.

Source: DelawareDepartment of Education (public reporting), 2026 collection. Not comparable across states — proficiency reflects different assessments and cut scores; graduation, dropout, and college-going use each state’s own cohort definitions and windows. Absent rows mean the state doesn’t publish that measure in a comparable file.
