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.
Connecticut state report card
Outcomes reported directly by Connecticut’s education agency — often more current than the federal series above. Because each state uses its own tests, definitions, and reporting windows, these figures are not comparable state-to-state; each row notes how Connecticut measures it.

College enrollment rate How Connecticut measures thisPostsecondary entrance rate: CT Next Generation Accountability Indicator 10 - share of the graduating class enrolling in a 2- or 4-year postsecondary institution (National Student Clearinghouse match), All Students, statewide; StateTot row, 0-1 decimal converted x100. The FallOfYear N accountability file is mapped to the Class of N (graduates of the prior school year), matching Indicator 8's verified one-year lag. | 67.0% | 2023–24 | |
Math proficiency (state test) How Connecticut measures thisSmarter Balanced Math, grades 3-8 combined ('All Grades Combined'), % of students with scored tests at Level 3 (Met) or Level 4 (Exceeded); N-weighted statewide aggregate computed by summing Level 3&4 counts and scored-test counts across 187 districts with published data. Denominator = 'Total Number with Scored Tests'. Participation rate ~99%. | 45.9% | 2024–25 | |
Reading / ELA proficiency (state test) How Connecticut measures thisSmarter Balanced ELA, grades 3-8 combined ('All Grades Combined'), % of students with scored tests at Level 3 (Met) or Level 4 (Exceeded); N-weighted statewide aggregate computed by summing Level 3&4 counts and scored-test counts across 185 districts with published data. Denominator = 'Total Number with Scored Tests'. Participation rate ~99%. | 50.3% | 2024–25 | |
Chronic absenteeism (recent) How Connecticut measures thisChronic absenteeism rate: % of students who missed 10% or more of enrolled school days (K-12), All Students, statewide; CT Next Generation Accountability Indicator 4, StateTot row.

Source: ConnecticutDepartment 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.
