How does CT compare nationally?

The National Assessment of Educational Progress (NAEP) is the only test given the same way to students in every state — making it the benchmark for state-to-state academic comparison. Below, this state's 8th-grade averages and where it sits on the 50-state distribution.

8th-grade math

280

+7 vs national avg (273)

8th-grade reading

268

+8 vs national avg (260)

Each dot is one state's 2024 NAEP 8th-grade averages. CT is highlighted in gold. Dashed lines mark national averages — being upper-right of both = above national in both subjects. Source: NAEP State Snapshot Reports. NAEP doesn't produce per-school scores — this is state-level context.

Sources: Public — NCES Common Core of Data via the Urban Institute API; "HS enrollment" = grades 9–12 (so K–12/combined records aren't inflated by their elementary grades); trend 2021–2024. Private — NCES Private School Universe Survey (PSS); enrollment is total students (PSS has no grade detail); trend 2018→2022 (biennial). "High school" = offers grade 12. Winners/losers shown for public only (comparable annual span) and exclude very small/near-closure schools.
