Five things to know

The district at a glance

Every answer links to the underlying measure. Reporting years stay attached to the data.

01Comparable nationwide

Student outcomes

How are students doing?

Four views answer different questions. State test percentages show grade-level expectations; the national research trend shows change over time; graduation and dropout measures describe high-school outcomes.

State proficiency standards differ and should not be used for cross-state rankings. Graduation ranges and privacy protections are preserved exactly. The academic trend uses Stanford Education Data Archive estimates and is not a state proficiency percentage.

Data status

8 of 8 national data layers are matched to this NCES district ID. Identity and school counts use NCES records. Academic estimates use SEDA, attendance uses EDFacts, finance uses NCES F-33, staffing and enrollment use 2023–24 NCES CCD where available, teacher certification, preschool and policy fields use the 2021–22 CRDC, and community poverty context uses Census SAIPE. Four-year graduation rates use 2022–23 EDFacts. Every detailed view preserves its reporting year.
